Drupal is an open source framework that publishers and developers can use to manage content. The primary purpose of Drupal is to manage content for websites. Drupal provides the structure so that website developers can design and develop sites without extensive backend programming. Programmers and developers can use a base code in Drupal, which uses PHP, for application development as well. Drupal provides themes and frameworks that developers can then use to customize sites and publish content online for their employer or personal website.
