Drupal

Drupal is a free and open source content management system (CMS) written in PHP and distributed under the GNU General Public License. It is used as a back-end system for many different types of websites, ranging from small personal blogs to large corporate and political sites, including whitehouse.gov and data.gov.uk. It is also used for knowledge management and business collaboration.

Drupal was also designed to allow new features and custom behavior to be added to extend Drupal's core capabilities. This is done via installation of plug-in modules (known as contrib modules) created and contributed to the project by open source community members. For this reason, Drupal is sometimes described as a content management framework. Drupal is also described as a web application framework, as it meets the generally accepted feature requirements for such frameworks.

Drupal can run on any computing platform that supports both a web server capable of running PHP version 4.3.5+ (including Apache, IIS, Lighttpd, and nginx) and a database (such as MySQL or PostgreSQL) to store content and settings.
