Drupal is one of the world's leading website content management systems (CMS). The system is similar in many ways to the easier to use Joomla CMS but has better membership management built into the core system. The content management area (admin area) is more difficult for non-experts to get to grips with but the system has many merits.

Drupal is often used in the following website types: 

• Community web portals
• Discussion sites
• Corporate web sites
• Intranet applications
• Personal web sites or blogs
• Aficionado sites
• E-commerce applications
• Resource directories
• Social Networking sites

Building a strong e-commerce presence is often better achieved by using the Joomla content management system.
