Category:DBMS content extensions

The  category contains articles on extensions that embed data stored in arbitrary databases. It also includes non-wiki article related data that is stored in the database backing a MediaWiki installation. Extensions that supplement the core MediaWiki database with tables linked via foreign key to page, user, or revision tables are not listed here. For information on these extensions, please see Category:Page content extensions and Category:User content extensions.
