--- SQL to create the initial tables for the MediaWiki database.
--- This is read and executed by the install script; you should
--- not have to run it by itself unless doing a manual install.
-
---
--- General notes:
---
--- If possible, create tables as InnoDB to benefit from the
--- superior resiliency against crashes and ability to read
--- during writes (and write during reads!)
---
--- Only the 'searchindex' table requires MyISAM due to the
--- requirement for fulltext index support, which is missing
--- from InnoDB.
---
---
--- The MySQL table backend for MediaWiki currently uses
--- 14-character CHAR or VARCHAR fields to store timestamps.
--- The format is YYYYMMDDHHMMSS, which is derived from the
--- text format of MySQL's TIMESTAMP fields.
---
--- Historically TIMESTAMP fields were used, but abandoned
--- in early 2002 after a lot of trouble with the fields
--- auto-updating.
---
--- The Postgres backend uses DATETIME fields for timestamps,
--- and we will migrate the MySQL definitions at some point as
--- well.
---
---
--- The /*$wgDBprefix*/ comments in this and other files are
--- replaced with the defined table prefix by the installer
--- and updater scripts. If you are installing or running
--- updates manually, you will need to manually insert the
--- table prefix if any when running these scripts.

---
--- The user table contains basic account information,
--- authentication keys, etc.
---
--- Some multi-wiki sites may share a single central user table
--- between separate wikis using the $wgSharedDB setting.
---
--- Note that when a external authentication plugin is used,
--- user table entries still need to be created to store
--- preferences and to key tracking information in the other
--- tables.
