Advantages of ASP.NET - .NET Framework

What is ASP.NET?

ASP.NET is a server side scripting technology that enables scripts (embedded in web pages) to be executed by an Internet server.

* ASP.NET is a Microsoft Technology
* ASP stands for Active Server Pages
* ASP.NET is a program that runs inside IIS
* IIS (Internet Information Services) is Microsoft's Internet server
* IIS comes as a free component with Windows servers
* IIS is also a part of Windows 2000 and XP Professional

ASP.NET is a web application framework developed and marketed by Microsoft to allow programmers to build dynamic web sites, web applications and web services. It was first released in January 2002 with version 1.0 of the .NET Framework, and is the successor to Microsoft's Active Server Pages (ASP) technology. ASP.NET is built on the Common Language Runtime (CLR), allowing programmers to write ASP.NET code using any supported .NET language. The ASP.NET SOAP extension framework allows ASP.NET components to process SOAP messages.

ASP.NET has emerged as an answer to the problems that the developers used to face with the classic ASP. Since ASP has an extensive use, however, Microsoft ensured that ASP scripts perform without modification on a machine with the .NET Framework (the ASP engine, ASP.DLL, is not customized when installing the .NET Framework). Thus, IIS can accommodate both ASP and ASP.NET scripts on the same machine.

Advantages of ASP.NET

1.Division of Code from HTML:

To make a clean sweep, with ASP.NET you have the capability to completely detach layout and business logic. This makes it much simple for the programmers and designers to collaborate efficiently. There is also a high level of efficiency achieved through this.

2.Support for compiled languages:

The developer can use VB.NET and access those vital things like strong typing and object-oriented programming. Using compiled languages signifies that ASP.NET pages do not have the similar performance penalties which are all linked with interpreted code. ASP.NET pages are precompiled to byte-code and Just In Time (JIT) compiled when it is requested. All the requests henceforth made are directed to the fully compiled code, which is cached until the source changes.

3.Use services provided by the .NET Framework:

The .NET Framework offers class libraries that are usable by your application. Some of the chief classes help you with input/output, access to operating system services, data access, or even debugging.

4. Graphical Development Environment:

Visual Studio .NET offers a potential development environment for Web developers. It is feasible to drag and drop controls and set properties the way you do in Visual Basic 6. There is a full IntelliSense support, not only for your code, but also for HTML and XML.

5. State Management:

In answer to the problems which developers faced ASP.NET provides solutions for session and application state management. State information can, can be confined in memory or stored in a database. It is also sharable across Web farms, and state information can be recovered, in case the server fails or the connection breaks down.

6. Update files while the server is running!

You can update the components of your application while the server is online and clients are connected. The Framework will use the new files
at the same moment that they are copied to the application. The files which have become old and needs to be removed are still in use are kept in memory until the clients have completed.

7. XML-Based Configuration Files:

Configuration settings in ASP.NET can be kept in XML files that are easily readable and can be edited. It is also easy to copy these to another server, along with the other files that include your application.

ROR Open Source Web Application Framework

Ruby on Rails is an open source web application framework coded in Ruby that follows the Model View Controller (MVC) architecture. Ruby is an object oriented scripting language. Rails is a Model-View-Controller (MVC) framework based on Ruby and used for developing web applications. The Rails framework supports MySQL, PostgreSQL, SQL Server, DB2 and Oracle databases.
Ruby on Rails is separated into various packages, namely ActiveRecord (an object-relational mapping system for database access), ActiveResource (provides web services), ActionPack, ActiveSupport and ActionMailer. Prior to version 2.0, Rails also included the Action Web Service package that is now replaced by Active Resource. Apart from standard packages, developers can make plugins to extend existing packages.
A content management system provides the foundation for an easy to maintain a website. A key factor in deciding which CMS to use should be the customization factor. When I say customization factor, I mean the how difficult it is to develop custom functionality particular to your project. Some CMS systems make this easy while others present more of a challenge.

A minor phenomenon has swept the Web world in the last few years. Like many things in the realm of software, it was over hyped. I'm talking about the open-source Web development framework called Ruby on Rails. The RoR market is more than ready for anything that gives them visibility into their applications, whether that is on the developer's desktop or the running production application.

Ruby on Rails, also known as RoR, is an open source web programming application framework meant for faster web applications. The Ruby programming is a free program and is constantly improved by Ruby on Rails Programmers to make it more better and user friendly. Ruby on Rails development comes with features such as Model View Controller architecture that separates data from logic i.e. presentation layer and helps in organizing application program. RoR database access library simplifies data handling. Rails framework has an extensive AJAX library which it uses to generate AJAX code and the required Java script is automatically generated.

Benefits of Ruby on Rails include:

1. Rails works well with various web servers and databases as it is really easy to deploy web solutions using Rails.

2. With Ruby on Rails work is done faster otherwise before web applications which were using languages such as PHP, Java, ASP, could take ages to complete and in the end you may just have a large stack of unmentionable codes.

3. Rails provide fast and easy development with quality results.

4. With Ruby programming language you need to write few lines of code in comparison to other programming language to reach the same result.

5. The Ruby on rails framework software also supports MySQL, SQL, SQL Server, DB2 and Oracle.

6. ROR CMS provides very flexible solutions, final output depends on user choice no pre-format is mandatory, image cropping, resizing, multi-language support, excellent usability, sort able tree-based admin interface, layout editor, scaffold template is created.

7. Rails applications are Tailor made to perfection for an individual or an enterprise and best fit for all kind of web application. Rails architecture is used and most preferred for development of cms, e-commerce, portals, collaboration, and community.

The new performance management and profiling tools are important additions to the RoR development community as RoR moves from being a hobbyist development language to a bona fide enterprise development framework. Most of our attention now is moving over to the general rails environment and ecosystem creating tools and environments for development and production so that people can work better with and on their rails applications.

Flex Application - Powerful Tool For Developing

Have you planed to make rich and interactive application? It is little bit difficult for developing good and interactive applications. Flex makes it easy and fast to build applications. This is especially due to the many standard components. Much can be modified in Flex, such as colors and properties such as shadows and corners. The most common approach building software appliances, is to build it with the standard components and skin it later on. This not only affects the design, but also does not involve the end user in the process. Flex is a powerful tool for developing rich internet applications but for beginners, Flex may be a bit overwhelming. Perhaps you understand the basics of Flex and what it can do for you, namely some of the beneficial features like cross compatibility, but you lack a concrete understanding of the ins-and-outs of the platform. This article will suggest some methods for familiarizing yourself with Flex as well as methods for laying out applications, making code changes, repeating components, and managing data.

Sample Applications are Great Learning Tools

Unless you're an expert, you might find it beneficial to do some practice with Flex before you start developing applications. There are a number of sample applications that you can manipulate in order to familiarize yourself with Flex and exactly what it can do. Flex can be utilized to create simple applications that feature the basic building blocks of application development, but also gives developers the power to create complex, interactive applications. Many of the major features in flex can be surveyed using Flex Explorer. Quickly learn about these major features as well as the kind of control that Flex gives to developers.

Using Containers and Controls to Lay out Applications

In simpler terms, containers are the components of a user interface that allow you to control the layout of your application. Child sizing, positioning, and navigation are examples of features that are controlled by containers. Buttons, Text Area, and Combo Boxes are examples of controls that are components of the user interface. MXML tags are used to bring containers and controls to your application but developers can also use ActionScript to add them at runtime.

Enhancing Performance with Code Changes

There are a number of facts that developers should consider when creating their applications. The smooth operation of applications is vital to their success and as such understanding code changes can be crucial for enhancing performance. For example, start up times for applications are slowed drastically when you have too many levels of nested containers. Similarly, applications can be slowed by Macromedia Flash Debut Player and by the use of trace statements. Slowed performance is a considerable annoyance to the end user and as such you should always be sure to test your application in both Flash Player and Flash Debug Player to ensure smooth running.

A container’s creation policy property can help you determine when you should create components at runtime. Applications can create components at various stages: at start up, when users navigate to a container, or even because of user interaction. Therefore, you should configure an application so that it is laid out incrementally at start up. Likewise, the position, width, and height of components are customizable so that start up time can be enhanced. Moreover, performance can be improved with the Grid container but only when controls are required to line up horizontally and vertically. As you can see, the developer has a number of tools and resources to improve performance at every stage of the development process.

Repeating Components

Developers are always looking for the best way to dynamically repeat components. In Flex, you have a choice between the Repeater object, Horizontal List, Tile List, or List control. Better performance can be achieved by replacing layouts as is appropriate. For example, during the Flex 1.0 timeframe, you can replace layouts created using Repeater with a combination of a Horizontal List or Tile List and a cell renderer.

If you want to repeat a small number of simple user interface components, you can use the Repeater object. Examples of this layout include Radio Button controls or other controls that are used in Form containers. On the other hand, if you want to display more than a few repeated objects, you can use the Horizontal List, Tile List or List control.

To display data horizontally, much like an HBox container, you can use the Horizontal List. Items are always displayed from left to right when using the Horizontal List while the Tile List displays items in a tile layout, as you would expect from the Tile container. Therefore, Tile List provides the direction property that decides whether the next item is down or to the right. The List displays items in a single column and all these controls, Horizontal List, Tile List, and List, instantiate all objects that can be seen in the list.

Data Management

Finally, Flex provides a number of resources and tools for managing data. Using MXML tags you have a number of options for data management. You can send data to server-side data sources using HTTP Post and GET commands, Java objects or other web services. You can also receive data from these server-side data sources and even share data between client-side items in your application. Furthermore, data can easily be stored in client-side objects. Moreover, data can be manipulated before it is used or displayed; for example, you can format data before it is displayed in the user interface and you can validate your data before it is used as well.

As one of the most versatile developer platforms, Flex has quite the reputation to live up to. Developers choose Flex because of the range of control they experience and also because of the design and style elements of Flex. Whether you’re looking to build a very simple application or you want to create a uniquely rich internet application that features all the bells and whistles of modern RIA, Flex gives you the tools you need.

Open Source - Php Application Development

Open source describes practices in production and development that promote access to the end product's source materials. Some consider open source a philosophy, others consider it a pragmatic methodology. Before the term open source became widely adopted, developers and producers used a variety of phrases to describe the concept; open source gained hold with the rise of the Internet, and the attendant need for massive retooling of the computing source code. Opening the source code enabled a self-enhancing diversity of production models, communication paths, and interactive communities. Subsequently, a new, three-word phrase "open source software" was born to describe the environment that the new copyright, licensing, domain, and consumer issues created.

PHP is a powerful tool for making dynamic and interactive Web pages. PHP is open source, meaning that everyone has free access to the source code and can use it for own development purposes. PHP provides high compatibility with leading operating systems and web servers such as thereby enabling it to be easily deployed across several different platforms. PHP extensions include support for features such as XML parsing, compression utilities, dynamic generation of images, translation functions etc.

Here are some advantages why use PHP?

* Easy integration
* Flexibility
* Free Open Source
* PHP l run on any platform
* PHP is extendible
* Better performance and reliability
* Can be easily embedded into HTML cod
* Compatible with servers like Apache and IIS
* PHP programming syntax is similar to C and C++ thus easy understandable by programmers.
* The most recent version of PHP is very stable.
* Easy Availability of resources

PHP have full objected oriented support and huge capability to build any sort of application which can run in web browser. PHP is an open source language and hence free access to the source code is available for your development. It can be easily installed and we do not require paying thousands of dollars for registration. The most recent version of PHP is PHP5 which is really very programmer friendly and completely object oriented. PHP extensions include support for features such as XML parsing, compression utilities, dynamic generation of images, translation functions etc.

The Security of PHP and MySql

This article provides a basis for understanding secure programming with PHP and gives a broader view of the subject. You should keep in mind that these guidelines identify only the most common threats and how to avoid them, reducing the risk of security compromise at the same time. The basic rule for writing a secure application is: never trust user input. Poorly validated user input constitutes the most severe security vulnerabilities in any web application. In other words, input data should be considered guilty unless proven innocent. Choosing php and mysql as programming language for a website is not enough. With open source coding being one of the inherent properties of php mysql development, securing your codes becomes essential. So when one allows the users to upload files on the website, then security is definitely at stake.

PHP Programming Protection

While it is not entirely possible to protect your site, yet there are few precautions that you can incorporate for better protection of PHP programming. Some of these are:

• You should check the referrer, for being sure that the information sent is from your website and not an outside source. Since, there are maximum chances of the information being fake.

• Restriction of the type of extension files being uploaded on the website is yet another method of security check.

• Renaming files is another way in which the program can be secured. This procedure involves the checking of double-barreld extensions like yourfile.php.gif.

• Changing the permission command for the upload folder so that files within it are not executable.

• All the alterations created by the user should be allowed only when they ‘Login’ into the database. On the other hand the owner of the site should always keep a close watch on all files being uploaded and then make them live.

Mysql Programming Security

Another aspect in php and mysql web development is the protection of the mysql libraries. Therefore, the most important aspect involved in protecting the mysql program is the security of the entire server host.

Securing MySQL is very essential for the smooth running of the website. This is based on Access Control Lists and SSL-encrypted connections, for protecting the php mysql web development program from random users visiting the website.

Some of the vital things to be considered for online site protection are:

• Accessing of the mysql database should not be allowed for any and everyone.

• Privileges to the users should always be accompanied with some restriction. If one can easily connect to the server without any ‘login’ then the security level code of the MySQL server should be rechecked.

• The MySQL database should be void of plain-text passwords. Use programs like MD5 (), SHA1(), or some hashing function for complete protection.

• Do not choose passwords from dictionaries, since they can be hacked easily. Use programs that break the passwords.

Therefore, the successful development of a website through php and mysql web development is complete only when the site owner consults a professional programmer. They expertise in the optimization of the MySql hosting database. This program is dynamic in nature and is an effective tool in the creation of browser-based applications.

Ajax Applications For Your Websites

AJAX enables you to write interactive applications while reducing the amount of data interchanged between the web browser and web server. This results in shorter processing times so you can give your user the ultimate web experience.
AJAX. Asynchronous JavaScript and XML, if you must know what it stands for. Don't let that put you off. Even if it is comprised of technical words and yet another acronym, more importantly, what is it, and why do you need it?
Why to use Ajax?

Mainly to build a fast, dynamic website, but also to save resources.

For improving sharing of resources, it is better to use the power of all the client computers rather than just an unique server and network. Ajax allows to perform processing on client computer (in JavaScript) with data taken from the server.

The processing of web page formerly was only server-side, using web services or PHP scripts, before the whole page was sent within the network.

But Ajax can selectively modify a part of a page displayed by the browser, and update it without the need to reload the whole document with all images, menus, etc...

For example, fields of forms, choices of user, may be processed and the result displayed immediately into the same page.

Remember the internet up until recently? Virtually all web pages were lifeless objects, similar to pages in a magazine, with no intelligence. In order to get a response from a website, you would click a link or press a submit button, and your computer would send a message to the computer hosting the site that it needs to send you back the next page. A little bit like turning to a new colourful but lifeless page in your magazine.

Sure, there were some really great new technologies that came along to make the internet more interesting. Animated images, Flash animations, small embedded applications, and scripts downloaded with the page certainly made the pages a lot more interesting. Yet, when compared to the highly responsive environment of your desktop computer, a web page really could not compete. Click anywhere in your local pc environment and you get an immediate and logical, virtually instantaneous response from the object you clicked, without your entire screen flashing blank and reappearing again from scratch. Do the same on a web page until recently, and usually at best you would have to wait a few seconds for a completely new page to reappear, a newly turned page in your virtual magazine.

Until Ajax. Technically Ajax is actually not a new technology, but a clever grouping of a few existing technologies. What has made Ajax a workable solution is that most people have started using browsers capable of supporting these technologies, often without even realising that their browser wields these dormant superpowers.

Ajax allows your internet page to respond to a user very similarly to the way your local computer desktop environment would. In a well-developed Ajax-based site, when you click on a page object, it responds almost immediately. Any changes to the page happen there and then, without the page disappearing and a new one replacing it. The result? A much more pleasant user experience. Once more, computers are becoming more interactive and responsive.

The concept can be a bit difficult to grasp initially, so here's a simple example from the RealmSurfer website to demonstrate the concept: Ajax example: search page. At first glance this looks like any other search page. Notice that advanced search link underneath the search box? When you click it, notice that you instantly get a whole lot more functionality inserted into the page -- no page refresh. Click the link again and the process reverses itself.

This is just a very simple example of the benefits of building Ajax functionality into your site. To get a look at some really powerful applications, have a look at a few popular Ajax-enabled websites:

Flickr -- one of the first sites to popularise the Ajax phenomenon, it's still one of the best ways to share pictures with your friends and family online. Yahoo was quick to realise the potential, and purchased the company a while back.

Protopage -- create your own customised, interactive home page. From the moment you land on the site, you can move objects around the page as if they are windows on your desktop, and interact with them just as easily.

There are plenty more Ajax-powered sites, and every day a whole lot more become available. What makes this technology so special? Here are a few good contributers:

* It uses relatively well established browser technology -- no plugins are needed, and most browsers these days are fully capable of supporting Ajax-enhanced pages.
* For the most part pages are still recognisable by search engines, meaning that unlike technologies like Flash, search engines will still understand what your page is about.
* It's economical. Instead of downloading a whole page when all you want to know is the weather, a well designed Ajax-based site will only download the information you need, leaving everything else perfectly intact.
* It's fast and responsive. Because much of the programming code that makes an Ajax-based page so useful is downloaded onto your local computer, much of your functionality is very fast and responsive, the same as any locally installed program.
* It's non-proprietary technology. Ajax is a combination of established web standards. You will never have to pay to use it, and neither will the people who program it for you.

Providing tips for what to consider when choosing a web developer:

Look for Specialization

Many web developers claim that they can do it all. The truth is that most web developers are primarily either graphic designers or programmers. The fields of graphic design and programming are fairly specialized and it is uncommon to find people who are able to do both well. When looking for a web developer, we suggest asking the professionals to designate who will be designing your web site and who will be doing any custom programming. If it is the same person doing both pieces, we advise paying even closer attention to their portfolio.

Look for a Strong Portfolio

The sites that a web developer has worked on are typically strong indications of the type of work that you can expect from them for your own web site. When reviewing a developer's portfolio, keep an eye out for aspects that you want incorporated into your own site. If you are looking for a bleeding edge design, then look for those types of designs in their portfolio. If on the other hand you are looking for complex programming, make sure you tell the developer that you would like examples of those types of sites.

Expect a Focus on Marketing

In the early days of the Internet, simply having a web site was enough because not every company had one. Today however, a web site is an important aspect of marketing for small businesses. Make sure that your web developer will perform search engine optimization on your web site and that they will help you increase your rankings in search engines.

Understand Who Will Host Your Web Site

How a web development company hosts the web sites that they create is an important but often overlooked aspect of choosing a web developer. Many web development firms simply act as a reseller for a company that performs the hosting. The danger with this is that if you experience problems with your web site or email it sometimes isn't clear who is responsible for fixing the issue. This can result in finger pointing between the web developer and the company involved in hosting the site when a problem occurs. This can be especially problematic with complex web sites that perform e-commerce or other custom functionality. Make sure that you understand who is responsible for assisting you with any hosting or email issues that you have before signing on with a web developer.

Think Long Term

There are several long term considerations that should be considered in your decision of which web developer to use. Make sure that you understand how ongoing maintenance will be charged and at what point your initial project ends and the maintenance phase of your relationship begins. It is also important to make sure that if your web developer will register a domain on your behalf that they put it in your name or the name of your business. This ensures that you can gain complete control over your domain in the event that you need to make a change to your hosting without the assistance of your web developer. Additionally, make sure that you have a copy of your web site. We're always surprised at the number of people who spend many thousands of dollars on a web site but don't have a copy of it in their own hands.

Request References and Actually Call Them

Once you reach the point where you have a web developer that you want to use, we recommend that you request references and actually call them. This will be one of your best indications of how the developer maintains and manages client relationships and it provides one last measure of safety before you begin your project.

Java Mobile Programmers - What is a Mobile Application?

Most mobile applications use the Java Micro Edition (Java ME) platform, which was developed for small devices like mobile phones, but is now used on a wide variety of devices. Java ME uses scaled down subsets of Java SE components, virtual machines and APIs. It also defines APIs that are specifically targeted at consumer mobile and embedded devices. One of the major and the most popular cell phone application software program is java.
Java is a programming language originally developed by James Gosling at Sun Microsystems (which is now a subsidiary of Oracle Corporation) and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities. Java applications are typically compiled to bytecode (class file) that can run on any Java Virtual Machine (JVM) regardless of computer architecture. Java is general-purpose, concurrent, class-based, and object-oriented, and is specifically designed to have as few implementation dependencies as possible. It is intended to let application developers "write once, run anywhere". Java is considered by many as one of the most influential programming languages of the 20th century, and widely used from application software to web application.

It is not just an application and is considered as a programming language for the most part. Java micro edition is the program which is incorporated within a cell phone and it facilitate a cell phone in a whole new way. It’s an efficient process through which development of small applications and devices gets simple and less complicated because most of the time these methods are advanced and rather complex to be completed. Incorporation of java within cell phone can only be done by professional java mobile programmers and for this reason; they bear lot of importance when it comes to the java incorporation within a cellular phone.

Every time you go on to purchase a cell phone or any other scientific device, you mainly focus on the kinds of applications it involves and features it has to offer. The games, softwares and specifications of a mobile phone make it different from many others and this is probably the reason why there is a gradual price range alteration in the market. There are a lot of complex procedures and phenomenons are followed in order to create these cell phones and micro applications. The person responsible for carrying out the complex procedures of programming a cell phone are known as mobile programmers.

These java mobile programmers are highly skilled individuals and are completely aware of the basics and complex procedures of java language. Incorporation of java within cellular phone is very much beneficial for cellular users because with java, they can now enjoy different games, software and applications.

Now let’s discuss some of the complex procedures which these java mobile programmers follow in order to incorporate java within the cellular phone, in the very beginning, these java mobile programmers focus on the small or micro applications which they would be using for the incorporation of complete java application within the cellular phones. CLDC and MIDP are the micro applications which are incorporated within the cellular phone to ensure that proper working of java application within the cellular phone. After this, with the help of wireless toolkits, java mobile programmers complete the coding, compiling and testing of the java application with the help of various techniques. After following these complex procedures, professional java mobile programmers incorporate java within the cellular phone which makes sure that cellular user enjoy latest technology within their palms.

Web Development Frame Work - Ruby on Rails

In the last four years, we have seen how Ruby on Rails (RoR) built on, and accelerated the wider acceptance of, the object-oriented Ruby language.
With Ruby on Rails hype in IT industry we have seen proportionate increase in performance and scalability problems. Ruby on Rails was extracted from Basecamp by David Heinemeier Hansson, is a framework for web application. Ruby on Rails development India offers Ruby on Rails offshore outsourcing web development and is based on open source web platform, LAMP. Ruby is object oriented programming language, it is blend of different languages – it has taken concept from Smalltalk, ease to use from Python and reality and flow from Pearl.
Ruby on rails is largely gaining grounds in the web development world, due to its ‘instant-web development’ concept. In absolute synergy with times, the ROR developers have been consistently gaining extra edge over other developers, given the optimal utilization of its single, yet highly effective speedy web development strategy. The embrace of this winning feature leads to a Win-Win situation for the clients and the company alike.

Ruby on Rail is a free web application framework, which intends to increase the speed and straightforwardness with which database-driven web sites can be created and offers skeleton code frameworks from the outset. Often shortened to Rails, or ROR, Ruby On Rails is an project written in the Ruby programming language and applications using the Rails framework are developed using the Rails framework are developed using the Model-View-Controller Design Pattern.

Rails is a full-stack framework for developing database-backed web applications according to the Model-View-Control pattern. From the Ajax in the view, to the request and response in the controller, to the domain model wrapping the database, Rails gives you a pure-Ruby development environment. To go live, all you need to add is a database and a web server.

The fundamental Ruby on Rails Web Development includes

The fundamental Ruby on Rails principles includes Convention over Configuration (CoC) and Don't repeat yourself (DRY).

"Don't repeat yourself" means that information is located in a single unambiguous place For example, using Active Record, the developer does not need to specify database column names in class definitions. Instead, Ruby can retrieve this information from the database.

"Convention over Configuration" means a developer only needs to specify unconventional aspects of the application. For example, if there's a class Sale in the model, the corresponding table in the database is called sales by default. It is only if one deviates from this convention, such as calling the table "products sold” that one needs to write code regarding these names. Because of these strict defaults, Rails is often referred to as "opinionated software", which has been a point of contention for many critics of Rails.

Follow up professional development sessions with small study groups that meet weekly, allowing participants to develop the shared language and common understanding necessary for acquiring new knowledge and skills. Larger study groups from different schools can hold monthly meetings-face-to-face or virtually-focusing on shared interests or projects.
Don't rush online learning. Working entirely online is new and uncomfortable for most of us. Online communities will dissolve if there is nobody to facilitate them and to help build the feeling of community. Combine online learning and face-to-face meetings, especially at first, so that people can get to know one another and build a mutual set of goals.
Create summer learning experiences. Provide summer institutes, when teachers have the time for hands-on experiences, and encourage sharing, playing, experimenting, and learning.

If you have your own web site, then you may be the right person to tell the world about the advantages of having one. Yes, a web site is not just about selling and promoting products and services, it’s also about creating one’s brand image in front of the entire world. The internet has the widest mass appeal, and hence through a well-designed and neatly presented website, one can easily brand his/her product thus brining decent business sense to his/her endeavor. Web sites development is one of the crucial factors that highly influence the business environment of anyone. Using the most innovative and advanced website development programs, anyone can get that edge in his/her mission, that too, at affordable process.

The look and feel of your web site has the capability to influence many visitors in their maiden visit to you. As a smart business maker, you need to be able to catch their fancy for long and a neatly designed web site can do that for you.

Ajax Programming - Ajax Development Services

Are you using AJAX to create interactive web applications?
Ajax is a group of interrelated web development techniques used on the client-side to create interactive web applications. Like DHTML and LAMP, Ajax is not a technology in itself, but a group of technologies. Ajax uses a combination of HTML and CSS to mark up and style information. With Ajax, web applications can retrieve data from the server asynchronously in the background without interfering with the display and behavior of the existing page. The use of Ajax techniques has led to an increase in interactive or dynamic interfaces on web pages. The technology is advancing at a lightening fast pace and making way to more innovations which have made a difference in today’s world. One such revolution that has dramatically transformed the virtual web world is Asynchronous JavaScript and XML or AJAX. If you have heard a lot about this word and are curious to explore as to what sort of profit it will incur to your website, this is the right article for you to acquaint yourself with this technology. This application has made Google Maps, an instant hit with the users, thanks to its quick page loading which allowed the users to scroll down the maps very conveniently without waiting the page to get loaded. This has resulted in the increase of the AJAX development service waiting to cater to the needs of the website owners.

Ajax will give you a respite by allowing your webpage to load in fraction of a second, a very less time for those whose heavy websites take ages to upload. And this has been a phenomenal hit amongst the users. However, you must realise the Ajax services only gives parity to the users. There are websites like eBay and Amazon, which are minting money without the usage of Ajax application development and still going strong with each passing day. The benefit of this application is that it gives the users an extra level of advancement that makes it easier for all users to use and thus admire it. Big players like Yahoo Maps and MapQuests have also shifted to Ajax thus giving way to better navigated websites.

At the face value, Ajax may look a very user friendly application. However, you must be careful in implementing this into your website. The Ajax development companies may go gaga about the benefits of this application, but it has its own disadvantages. The application might make your website more confusing, forcing the visitors leave the website without exploring it. The Ajax would not use the back button feature as a user might expect. Also the bookmark feature also doesn’t work very well with this application.

So, the usage of Ajax application should be done under caution. If you are doubly sure about its pros and cons and convinced about its usage, only then you should use this application.

Database Management - Understanding Database Management

A Database Management System is an application that manages the creation and access of databases. Database management enables a structured way of storing and accessing data for different users and softwares. It requests data from a specific application and tells the computer's operating system to appropriately transfer that data. Having a Database Management System makes it easy for an organization to change its information systems easily as the organization itself grows and its requirements for storing data change. The existing system of managing the organization's database will remain the same even when new categories are added.


If you feel that you need a new association management system in order to improve your marketing abilities, well it’s not true in the most cases. You can simply improve your database and it will be helpful for your organisation. You must realise that managing a database is not just an event, but it is a process. Let us look into the three most important facets of a database management. They are

Collection- where you find new prospects, and sales transactions are done Active Management- where the data is reviewed and its accuracy is ensured Query and Reporting- the data here is used for reporting, communicating and marketing

If you understand these three broad categories, this will help you troubleshoot at the times of problem. Every user database has these broad categories and that can help us determine as to why we have this problem. Let is study these in detail

Collection – the question that we should ask ourselves is that are we actually collecting the right data that will help us with our marketing? If we are writing down the details of the clients, we need to ensure that the details are relevant enough. If required, more information should be added in the database so that there is adequate amount of information.

Active management- this is the second set of questions that we should be looking at. That is- is the data given in your database management system accurate and updated? Are all the details filled in the database correct? For example the addresses or the updated emails IDs of the clients? If not, then you should work out on those details.

Querying and Reporting- we have ensured that we have the most correct data and the information is fully updated. We should see if the data can be easily pulled out of the database if the need be. If this is what gives you problem, you need to work on this step.

So, these are the three broad steps of an effective data management. You need to ask your database manager about these steps before you jump on to concluding that your database is not effective useful.

Kill Session In Oracle Using Command

What is a means or method to kill inactive sesions? Our database sessions do not end and remain in inactive status even if the users log out from the application and we are required to kill it manually. One of the most common mistakes that I see are DBA's killing the wrong session. When killing a session, carefully review the session, process and SQL associated with the offensive task. Before killing the session, the DBA may decide to view the SQL being executed by the session. This can be obtained by using the TID above (300) in the following SQL statement:

select
b.username,
a.sql_text
from
v$sqltext_with_newlines a,
v$session b,
v$process c
where
c.spid = to_number('300', 'xxx')
and
c.addr = b.paddr
and
b.sql_address = a.address;


In various critical situations Oracle DBA has to decide to kill existing session or kill the background process of Oracle. At this moment remote Oracle DBA should need to terminate session/process called as murder of session.

Which situation kill session or process needed:

Then question is raised that in under which type of situation remote dba should need to kill session and process. We are explaining those situations and incidences of database.Some critical situation Oracle DBA should need to take decision to ternminate session.

Kill session needed under following typical and critical circumstances.

1. When blocking lock occurs and other sessions are waiting to acquire a lock on same object. But blocker session doesn't end the transaction. At this moment Remote oracle dba should need to identify blocking session and terminate it for clearing resources for other sessions.

2. When maximum connections reached error occurs. No room available for any new connection or session. At this time Remote Oracle DBA should need to kill some of idle processes from Oracle database.

3. When database found in hang status and shutdown abort command also doesn't work, at same time Remote Dba should need to terminate instance abnormally with murdering background processes.
In above critical situation we need to kill or terminate or murder some session or process using command line or GUI utility like OEM, TOAD etc. But command line is more easy and helpful to solve such critical situation in remote DBA support services.

How to kill session using command line of Oracle:

Using SQL*Plus (kill session with alter system command): It is very simple way to kill session using SQL command. Just check serial no and sid (system identifier) from v$session view as follows and use "alter system kill session" with sid and serial# command. SQL>select sid,serial# from v$session where machine='GPTWORKGROUP';

SID SERIAL#
--------- ---------
9 171
1 row selected

SQL> alter system kill session '9,171';
System altered.
OR
SQL>alter system kill session '9,171' immediate;
System altered.

And terminated user session will get message in sqlplus that "your session has been killed". We can get output of status as "killed" from v$session for terminated session.

Ruby on Rail Guides - Ruby Development

Ruby is seen as a flexible language, since it allows its users to freely alter its parts. Essential parts of Ruby can be removed or redefined, at will. Existing parts can be added upon. Ruby tries not to restrict the coder. After taking a decision to launch a Web 2.0 project, independent software vendors (ISVs) can get overwhelmed with hundreds of thoughts, concerning the future project and its performance. However, the idea of choosing between various Web technologies available at the moment may bring in some confusion. What would be more beneficial, Adobe Flex, Silverlight, JavaFX, Ruby development, or whatever? In fact, each technology has its peculiarities and, depending on the type of a planned project, you can choose the one that better meets all your requirements. If you are considering Ruby development, there are facts well worth your attention.

Ruby on Rails is a simple, but nonetheless powerful open source Wed development environment. Ruby development entered enterprise market by virtue of its obvious advantages, including less code, integrated testing, flexibility of the Model-View-Controller design pattern, and rapid Web development enabled by this technology. For instance, it takes a Ruby developer around 15 minutes to produce a new blog engine and around five to create a new image search system.

The remarkable thing about Rails is that it has its own philosophy, introduced by David Heinemeier Hansson, who first released Ruby on Rails as open source in July 2004. According to the Ruby development philosophy, two main principles are emphasized:

1. Convention over Configuration (CoC). According to this principle, most part of configuration data can be omitted by implementing practical conventions (conventions can surely be overridden with configuration, when there is a need to do that). 2. Don’t Repeat Yourself (DRY). As for Ruby development, it means that each element of any Web application is specifically located and there's no need to repeat it several times across different files. If a developer uses, for instance, the ActiveRecord module of Rails, there’s no need to specify database column names in class definitions. This information can be retrieved from the database based on the class name. This principle is applied not only in Ruby development, but other technologies, as well.

Some Ruby developers also suggest the third principle to be included, which is

3. Quick Turn-Around Time. When a developer provides an integrated Web server and an integrated language, it is possible to see the results of code changes straightaway. This sufficiently lessens the amount of code-debugging work.

The philosophy of Ruby development has appealed to many Web 2.0 companies and, as a result, became the basis for such well-known projects, as Twitter, Yellowpages, BaseCamp, CrunchBase, etc.

As any other Web application framework, Ruby on Rails has its pros and cons. However, if rapid Web development is what you are looking for, then Rails is a technology to be seriously taken into consideration. After all, its philosophy significantly simplifies Web application development and thus allows energy to be directed at the creative side of Ruby development process, making your project stand out among the rest.

Introduction of Programming with C# Threads -C# Programming

This paper provides an introduction to writing concurrent programs with “threads”. A threads facility allows you to write programs with multiple simultaneous points of execution, synchronizing through shared memory. The paper describes the basic thread and synchronization primitives, then for each primitive provides a tutorial on how to use it. The tutorial sections provide advice on the best ways to use the primitives, give warnings about what can go wrong and offer hints about how to avoid these pitfalls. The paper is aimed at experienced programmers who want to acquire practical expertise in writing concurrent programs. The programming language used is C#, but most of the tutorial applies equally well to other languages with thread support, such as Java.
Almost every modern operating system or programming environment provides support for concurrent programming. The most popular mechanism for this is some provision for allowing multiple lightweight “threads” within a single address space, used from within a single program.
Programming with threads introduces new difficulties even for experienced programmers. Concurrent programming has techniques and pitfalls that do not occur in sequential programming. Many of the techniques are obvious, but some are obvious only with hindsight. Some of the pitfalls are comfortable (for example, deadlock is a pleasant sort of bug—your program stops with all the evidence intact), but some take the form of insidious performance penalties.
The purpose of this paper is to give you an introduction to the programming techniques that work well with threads, and to warn you about techniques or interactions that work out badly. It should provide the experienced sequential programmer with enough hints to be able to build a substantial multi-threaded program that works—correctly, efficiently, and with a minimum of surprises.
This paper is a revision of one that I originally published in 1989 . Over the years that paper has been used extensively in teaching students how to program with threads. But a lot has changed in 14 years, both in language design and in computer hardware design. I hope this revision, while presenting essentially the same ideas as the earlier paper, will make them more accessible and more useful to a contemporary audience.

A “thread” is a straightforward concept: a single sequential flow of control. In a high level language you normally program a thread using procedure calls or method calls, where the calls follow the traditional stack discipline. Within a single thread, there is at any instant a single point of execution. The programmer need learn nothing new to use a single thread.
Having “multiple threads” in a program means that at any instant the program has multiple points of execution, one in each of its threads. The programmer can mostly view the threads as executing simultaneously, as if the computer were endowed with as many processors as there are threads. The programmer is required to decide when and where to create multiple threads, or to accept such decisions made for him by implementers of existing library packages or runtime systems. Additionally, the programmer must occasionally be aware that the computer might not in fact execute all his threads simultaneously.


C# is a language developed by Microsoft that is similar to Java. C# Custom Programming has the power of C++ which is combined with the simplicity of C#. This language is supposed to be the best language for Microsoft’s .NET programming for some applications.

Advantages of C# Custom Programming

* The language is similar to C++, C and Java and thus helps to increase the readability.
* Features such as object inheritance and class declarations available with .NET are more advanced and smooth in C#
* C# is a simple and involves less typing as it is less verbose
* As compared to the VB.Net code, C# code executes faster in some cases, which leads to speeding up of the whole application’s performance.
* Unlike VB, C# does not allow un-typed variables, undeclared variables along with un-typed methods.
* As the language is flexible it is preferred by Microsoft
* C# compilers are available in every platform such as Windows, Linux, Mac, Solaris etc.
* C# syntax is cleaner than VB. Net and also allows embedding of blocks of pure C++ code as per requirement.
* As compared to C++, C# Custom Programming is simpler, safer and is more productive.
* As C# has the ability to interoperate with other .NET codes the overall process of development gets a lot easier.
* C# helps in XML documentation that is generated from other source code comments.

Basic Sofware Testing - Basic Experience

Software testing is an investigation conducted to provide stakeholders with information about the quality of the product or service under test. Software Testing also provides an objective, independent view of the software to allow the business to appreciate and understand the risks at implementation of the software. Test techniques include, but are not limited to, the process of executing a program or application with the intent of finding software bugs.

Running software testing projects is far more difficult than people outside of the software testing arena seem to realize. It is not uncommon for senior management, project management and development teams to adversely pressurize the test team to cut corners in order to meet delivery deadlines. Yes, everyone wants to release a quality product, on time and on budget. Believe it or not even the software testing team want to hit the delivery date, with a product that is on budget. Pushing the software testing team to cut corners is not the answer though.

Software Testing is an investigation carried out to provide information about the service or product to the stakeholders. It also provides and independent view to allow people to understand the inherent risks involved in using that software.
Thus it serves as a warning system and prevents possible losses if implemented correctly.

Different users require different softwares. For e.g. a banker would need banking software and a gamer would need gaming software. Hence when a company develops or distributes software, it should be able to judge whether its product is acceptable or not to its end customer and software testing allows it to do that. According to a recent study by NIST, bugs in software costs $60 billion annually to the US economy. A third of this can be avoided by conducting better software testing.

There are various reasons for bugs in software like programming errors, compatibility with earlier / later versions, hardware compatibility, etc. Software testing aims at examining the code and also executing it under test conditions.
Few techniques used for this purpose are:
1) Black box testing,
2) White box testing,
3) Grey box testing,
4) Integration testing,
5) Regression testing,
6) Acceptance testing,
7) Non functional testing and
8) Destructive testing.

As a common practice, an independent testing group does software testing before the product is delivered to the customer. There are many approaches towards software testing. It can be conducted on basic modules or units of the software individually. This is called unit testing. It can also be conducted on the entire software at the same time by putting it through some test cases. This is called system testing. It can be done to check its compatibility with other hardware and software. This is called integration testing. Before the product is dispatched to the client, additional tests called alpha and beta tests are done. Alpha testing includes testing the final version of the product by treating the testers as the end users. Beta testing is done after alpha testing by distributing the product to a select audience outside the testing group for feedback.
Software testing is advantageous as to an extent it can highlight bugs in the code, test the software compatibility with other hardware and software and predict customer response to a product. The limitation of software testing is that it is unable to test under all operating conditions. It can only test the product's failure under limited test conditions.
There are many certification programs that certify professional software testers. However no certification today actually checks the software tester's knowledge and ability in his field. A certification alone is unable to guarantee the tester's capability hence many believe this filed isn't ready for certification yet. However it is a fast emerging field and promises exciting careers for its aspirants.
