After seven years of running and collecting 2 Petabytes of physics data, PHENIX experiment at the Relativistic Heavy Ion Collider (RHIC) has gained a lot of experience with database management systems ( DBMS ). Serving all of the experiment's operations - data taking, production and analysis - databases provide 24/7 access to calibrations and book-keeping information for hundreds of users at several computing centers worldwide and face the following challenges: - Simultaneous data taking, production and analysis result in hundreds of concurrent database connections and heavy server I/O load. - Online data production at remote sites requires a high degree of Master-Slave server synchronization. - Database size ( presently 100GB with half of data added in the last few months ) raises scalability concerns. - Long life of modern HENP experiments and fast development of database technologies make prediction of the best DBMS provider 5-10 years down the road difficult and require investments in design and support of good APIs. In this talk PHENIX solutions to the above problems will be presented and the trade-offs discussed.
