Drupal version 6 was introduced in February 2008, while Drupal version 7 was introduced in January 2011.

Drupal is a content management framework or a CMS that allows users to build a website from the ground up without having to understand the programming language. However, Drupal is a bit complicated and does require extensive time to understand the workings of the system. It has a steeper learning curve, which means creating a website will take time. Drupal is best suited for complex or large-scale websites.

Drupal is a free and open-source content management framework (CMF) that is written in PHP language. It is used for blogging websites as well as for political and government websites. Wikipedia states that the standard release of Drupal, known as Drupal core offers features such as “user account registration and maintenance, menu management, RSS feeds, page layout customization, and system administration.” It can be used as a brochureware website, a single- or multi-user blog, an Internet forum, or a community website providing for user-generated content. Drupal does not require any programming skills from a developer for basic installation and administration. Drupal was initially written by Dries Buytaert on a message board, which further became an open source project. Drupal is derived from Dutch word ‘druppel’, which means "drop".
