Joomla is an open-source content management system (CMS), which means that its source code is freely accessible and modifiable by anyone.
Considered one of the world's most popular CMS, Joomla is a software platform that lets you create, manage and publish content on a website without the need for advanced technical programming skills. Whether you want to create a blog, a corporate site, an e-commerce site, a community site or even a government site, Joomla offers the flexibility and extensibility you need to set up almost any type of website.
Written in PHP, Joomla uses a database (usually MySQL) to store site content. It offers a user-friendly interface for administrators, enabling them to easily create and modify site content, manage users, categories, menus and much more.
Joomla is also known for its large community of active users, developers and contributors. This dynamic community creates additional extensions and plugins that extend Joomla's core functionality and add site-specific features.
