Drupal is an open-source content-management framework written in PHP used as a back-end framework for websites and is also used for knowledge management and business collaboration. The standard release of Drupal contains basic features common to content management systems, including user account registration and maintenance, menu management, RSS feeds, taxonomy, page layout customization, and system administration. Drupal runs on any computing platform that supports both a Web server capable of running PHP and a database to store content and configuration.
