Joomla is a free and open-source content management system (CMS) for publishing web content, developed by Open Source Matters, Inc. 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 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, search, and support for language internationalization.
Over 8,000 free and commercial extensions are available from the official Joomla Extensions Directory, and more are available from other sources. As of 2019, it was estimated to be the fourth most used content management system on the Internet, after WordPress and Drupal.
What’s a content management system (CMS)?
The definition of a CMS is an application (web-based), that provides capabilities for multiple users with different permission levels to manage (all or a section of) content, data or information of a website project, or intranet application.
Managing content refers to creating, editing, archiving, publishing, collaborating on, reporting, distributing website content, data and information.
