Linux grew the fastest of all the RDBMS platforms (84 percent), driven primarily by Oracle, and the maturation and user acceptance of the Linux platform as a mission-critical DBMS platform. RDBMS on the mainframe platform continued to show strength, growing faster than the Unix platform, and even beating the overall growth rate.

Gartner analysts said the worldwide RDBMS market is poised for continued growth through 2010 as data management and integration take on a strategic importance in an increasing number of organizations
