Joomla

Joomla is a free and open source content management system (CMS) for publishing content on the World Wide Web and intranets and a model–view–controller (MVC) Web application framework that can also be used independently.

Joomla is written in PHP, uses object-oriented programming (OOP) techniques and software design patterns, stores data in a MySQL or MS SQL database, and includes features such as page caching, RSS feeds, printable versions of pages, news flashes, blogs, polls, search, and support for language internationalization.
