Joomla is a flexible and powerful platform, whether you are building a small site for yourself or a huge site with hundreds of thousands of visitors. Joomla is open source, which means you can make it work just the way you want it to.
Beginners
Introducing easy JavaScript data access
So you want to rapidly prototype a really cool Web 2.0 JavaScript application, but you don't want to spend all your time writing the wiring code to get to the database? Traditionally, to get data all the way from the database to the front end, you need to write a class for each table in the database with all the create, read, update, and delete (CRUD) methods. Then you need to put some marshalling code atop that to provide an access layer to the front end. Then you put JavaScript libraries on top of that to access the back end. What a pain!
This article presents an alternative method in which you use a single database class to wrap multiple database tables. A single driver script connects the front end to the back end, and another wrapper class on the front end gives you access to all the tables you need.Figure 1 shows the complete stack.
Upgraders
If you are an experienced Joomla! 1.5 user, this Joomla site will seem very familiar. There are new templates and improved user interfaces, but most functionality is the same. The biggest changes are improved access control (ACL) and nested categories. This release of Joomla has strong continuity with Joomla! 1.7 while adding enhancements.
Professionals
Joomla! 2.5 continues development of the Joomla Framework and CMS as a powerful and flexible way to bring your vision of the web to reality. With the administrator now fully MVC, the ability to control its look and the management of extensions is now complete.
