Gartner Says Worldwide Relational Database Market Grew 10 Percent in 2004
STAMFORD, Conn., May 19, 2005 — Worldwide relational database management systems
(RDBMS) new license sales totaled $7.8 billion in 2004, a 10.3 percent increase
from 2003 revenue, according to Gartner, Inc.
IBM and Oracle were in a virtual tie for the top position based on new license revenue
(see Table 1). Gartner analysts said the difference between the two vendors was
less than $30 million, so statistically it is too close to identify a clear leader.
"Much of IBM's growth was generated by its DB2 on the zSeries platform, and IBM's
DB2 sales on the Unix platform performed well with nearly 9 percent growth," Colleen
Graham, principal analyst at Gartner. "Oracle saw strong growth of nearly 15 percent,
much of it coming from its performance on the Linux platform."

RDBMS on the Windows server platform totaled $3.1 billion in 2004, a 10 percent
increase from 2003. Microsoft extended its lead in this segment, as it accounted
for 50.9 percent of new license revenue.
RDBMS on the Unix platform declined 0.7 percent, however much of this decline was
attributed to Oracle's strong performance in the Linux segment. Oracle accounted
for 55.9 percent of RDBMS new license revenue.
The Linux RDBMS was still relatively small with new license revenue of $654.8 million
in 2004, but this segment showed the largest growth rate. Linux RDBMS new license
sales increased 118.4 percent from 2003 revenue of $299.8 million. Oracle was the
clear market leader in this space, as it accounted for 80.5 percent of new license
sales. Its revenue increased 154.8 percent.
Gartner defines RDBMS as a database management system that incorporates the relational
data model, normally including a Structured Query Language (SQL) application programming
interface. It is a DBMS in which the database is organized and accessed according
to the relationships between data items. In a relational database, relationships
between data items are expressed by means of tables. Interdependencies among these
tables are expressed by data values rather than by pointers. This allows a high
degree of data independence.
