Joomla is an open source platform on which Web sites and applications can be created. It is a content management system (CMS) which connects your site to a MySQLi, MySQL, or PostgreSQL database in order to make content management and delivery easier on both the site manager and visitor.
Drupal is free, open source software that can be used by individuals or groups of users -- even those lacking technical skills -- to easily create and manage many types of Web sites. The application includes a content management platform and a development framework.
