DB2
Big Blue puts the big into data centers with DB2. DB2 runs on Linux, UNIX, Windows and mainframes. IBM pits its DB2 9.7 system squarely in competition with Oracle's 11g, via the International Technology Group, and shows significant cost savings for those that migrate to DB2 from Oracle. How significant? How does 34 percent to 39 percent for comparative installations over a three-year period sound?
