According to Gartner, Inc., worldwide new license sales for relational database management systems (RDBMS) grew 10.3 percent in 2004 for a total of $7.8 billion. As far as new license revenue, Oracle and IBM landed in a virtual tie.
IBM’s DB2 had nearly 9 percent growth in sales on the Z Series and Unix platforms, whereas Oracle saw nearly 15 percent growth, largely due to its performance on the Linux platform. Although the new license revenue for Linux RDBMS was still a relatively small segment, this is where sales showed the most substantial rate of growth. Oracle is the clear leader in the Linux space, with 80.5 percent of new license sales.
