The SQL code that creates the MySQL/MariaDB core tables for any MediaWiki version—with extensive comments—is in the maintenance/tables.sql source file. The most important tables are probably page , revision , text and user .

Version history

The following table depicts the range of MediaWiki versions over which each table has existed in the schema. Red rows indicate tables that are no longer used by the core nor added by the installer as of a particular version. They might however still be used by extensions. Note, table headings are repeated every 10 rows for clarity.
