Oracle Corp.'s lead in the database software market shrank last year, as International Business Machines Corp. and Microsoft Corp. boosted sales, market researcher IDC said.
Oracle's share of the $13 billion market declined to 39.4 percent last year from 41.7 percent in 2001, IDC said. IBM's portion increased to 33.6 percent from 31 percent, and Microsoft's rose to 11.1 percent from 9.7 percent.
IBM and Microsoft gained on Oracle by charging less and by selling database software for smaller tasks or to small and medium- size businesses, IDC analyst Carl Olofson wrote in a report. Some Oracle clients have licenses bought two years ago that they haven't used yet, hurting the company's sales, Olofson wrote.
Microsoft is the world's largest software maker, IBM is second biggest, and Oracle is third.
