Database schema diagram of MediaWiki

Datenbankschema ansehen →

Das aktuelle MySQL-Diagramm für jede MediaWiki-Version—mit ausführlichen Kommentaren—kann in der maintenance/tables.sql Datei gefunden werden. Sehen Sie sich die neueste Version aus SVN: maintenance/tables.sql an. Bei Verwendung von Postgres, sollte stattdessen die maintenance/postgres/tables.sql betrachtet werden. Die wichtigsten Tabellen sind wahrscheinlich page, revision, pagelinks und text.

Since MediaWiki 1.35, the appropriate file is in the maintenance/tables.json source file, which is then transformed into maintenance/tables-generated.sql. In these versions maintenance/tables.sql is less relevant, though some tables are still in there that haven't been migrated yet.

The most important tables are probably page , revision , text and user .

Versionsgeschichte

Die folgende Tabelle zeigt die Bandbreite der MediaWiki-Versionen, über die jede Tabelle im Diagramm existierte. Rote Reihen zeigen Tabellen, die in einer bestimmten Version gelöscht wurden. Beachten Sie, Tabellenüberschriften werden alle 10 Zeilen für Klarheit wiederholt. 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.

Database management systems

In MediaWiki master, tables.sql is currently being migrated to maintenance/tables.json, and documenting comments should be found there instead of the resultant SQL files.

See the latest MariaDB/MySQL-compatible versions from Git: maintenance/tables.sql, maintenance/tables-generated.sql.

If using SQLite , the file maintenance/sqlite/tables-generated.sql and the unmigrated MySQL tables in maintenance/tables.sql should be viewed instead.

If using PostgreSQL , the files maintenance/postgres/tables.sql and maintenance/postgres/tables-generated.sql should be viewed instead.

If using Microsoft SQL Server, see maintenance/mssql/tables.sql. (entfernt in 1.34)

If using Oracle, see maintenance/oracle/tables.sql. (entfernt in 1.34)
