Hi, is it true that multiple Mediawiki websites must share the same database in order to share the same software? I have been combing the internet and this seems to be the case.
Nope.
Wikimedia's sites for instance use several distinct clusters of database servers, each of which includes master & slave servers for one or more wikis' individual databases.
In that particular configuration, some of those are also shared in that some wikis can slurp information from each other directly (Commons files) or indirectly (CentralAuth's central user database supplements the individual wikis' own user tables), but none of it's required. Most importantly, *NONE* of them are in the same database. Each wiki has its own database. (Actually, I'm not sure the cross-wiki communication stuff works at all if you do put them in the same database with different prefixes.)
