Yesterday I was presenting an internet banking solution to a potential client management. My offer is based on using MS SQL Server 2008 RDBMS.
One of the client's officers mentioned, that Oracle's RDBMS has some "specific" features that allow a security department to ensure that no sensitive data is visible to an admin, that MS SQL doesn't have.
For me it is hard to imagine how can this be mitigated, unless preventing access to some tables in a DB.
My question - is there really a "know-how" in Oracle RDBM when it comes to security tuning, that MS SQL does not implement?
