Drupal
Used on all our projects, Drupal is one of the most popular open-source Content Management System.
The great interest of Drupal lies in its reliability, its scalability and its wide choice of modules that add many features to a web application.
Drupal relies on a very active worldwide community. The numbers are staggering: 9 million sites worldwide, 30,000 developers actively contributing to the Drupal project, 25,000 modules available on Drupal.org, millions of pages of documentation ...
Unlike other CMS that are content with a "per page" vision, Drupal's reputation has been built on its approach, which is very different from its competitors: entities. Thus, in Drupal, data will be grouped by content type, classified using taxonomies.
This high level of abstraction allows for flexible content management.
