A content management system (CMS) allows you to edit and change your own content.  This is a great way for you to be able to perform updates to your own website (Website Content Management WCM) without having to purchase expensive software.

Joomla! won the Packt Publishing best PHP Open Source Content Management System Award in both 2006 and 2007.  Joomla came second in 2008.

The core Joomla framework enables developers to quickly and easily build:

* Inventory control systems
* Data reporting tools
* Application bridges
* Custom product catalogs
* Integrated e-commerce systems
* Complex business directories
* Reservation systems
* Communication tools

Since Joomla is based on PHP and MySQL, you can build powerful applications on an open platform anyone can use, share, and support.
