Table name prefix. If you only have access to a single database and wish to install more than one version of MediaWiki, or have other applications that also use the database, you can give the table names a unique prefix to stop any naming conflicts or confusion.
For example, if you use the prefix 'wiki_' then the table 'page' will be named 'wiki_page' instead.
You need to set this at the time of initial configuration, or manually change the table names at a later date. Changing this setting does not automatically update the names of the tables in your database.
