Well, it is a fairly standard SQL database. (open source). What were you specifically looking for? Some folks prefer Postgresql (pronounced Post - Gress - QL) it over MySql (My Sequel) on the right platform. Official Postgresql site [postgresql.org]. I don't think it runs on win 9x where MySql will.
