Just want to add, that comparing to postgresql is a very modern view. There were other databases, not popular today, but quite popular back in the day. To name a few: DB2, InterBase, Firebird, Paradox, Access, SQL Server Compact. MySQL was a really shitty database in early 2000s, still THE most popular.
