The Core Database

Much of the data we see in Joomla! is stored in the database. A base installation has over thirty tables. Some of these are related to core extensions and others to the inner workings of Joomla!.

There is an official database schema, which describes the tables created during the installation. For more information, please refer to: http://dev.joomla.org/component/option,com_jd-wiki/Itemid,31/id,guidelines:database/.
