Does anyone know what type of database system is used for online games such as EverQuest? What about Search Engines? I can''t imagine mssql being used. Oracle could probably do the trick for Online games such as EverQuest, but what about Search Engines? You''d think a Search Engine is more highly intensive on the database side of things. Do they use a custom propriatery database that isn''t an off-the-shelf product?
