what is joomla?

ABOUT  JOOMLA: 

Joomla was released on September 22, 2005. It is one of the most popular free content management systems (CMS) in the world that allows you to easily create and manage a dynamic website. It has an interface to control all the features and functionality this powerful CMS possesses. Furthermore, there are hundreds of free extensions written for Joomla that allows users to extend its functionality and customize it to their own objectives.

It is built on a model–view–controller web application framework that can be used independently of the CMS. Joomla is written in PHP, uses object-oriented programming (OOP) techniques (since version 1.5) and software design patterns. stores data in a MySQL, MS SQL (since version 2.5), or PostgreSQL (since version 3.0) database, and includes features such as page caching, RSS feeds, printable versions of pages, news flashes, blogs, polls, search, and support for language internationalization.

As of 2013, Joomla has been downloaded over 50 million times. Over 7,700 free and commercial extensions are available from the official Joomla! Extension Directory, and more are available from other sources.
