Joomla!

Joomla! is an open-source content management system (CMS) used to build and manage complex websites and online applications. Initially released in 2007, it is written in PHP and stores data in a MySQL database. It is particularly popular for creating community portals, corporate intranets, and e-commerce sites due to its robust user management capabilities.

Joomla! utilizes a powerful extension system that allows users to add complex features like forums, e-commerce carts, and SEO tools without touching the core code.

This highly modular architecture allows for varying levels of website complexity, from simple blogs to massive corporate portals.
