Debugging advanced applications

Debugging have become increasingly complex in web applications as there are too many elements taking part.

Common components
Let's start by inspecting the common components:

1. Database server
2. Web server
3. PHP
4. Framework
5. Application
6. Browser
7. JS
8. CSS
9. XML



The real problem with Rich Clients is that they hide information from us, the data comes in one of many formats "behind the curtains" making access to data very complicated.

It's important to notice that to debug these applications many times you will need good understanding of HTML, CSS, JS, PHP, XML and AJAX. If you don't feel confident about your abilities on some, request help from your peers or your project manager after you have pinpointed the problem.
