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 (since version 1.5[3]) and software design patterns,[4][5] stores data in a MySQL, MS SQL (since version 2.5), or PostgreSQL (since version 3.0) database,[6][7] and includes features such as page caching, RSS feeds, printable versions of pages, news flashes, blogs, polls, search, and support for language internationalization.
