Drupal is an open-source, free content management system programmed in PHP. It is cross-platform, supports multiple databases, and has become very popular as a web development framework among professional programmers and designers. Drupal started as a message board, but it was first released as an open source project in 2001. The name, Drupal, is an anglicized version of the Dutch word “druppel”, which means “drop”, which is where the iconic water-drop mascot came from.
