Oracle maintained its dominance of the database market last year, despite fast growth by Microsoft's SQL Server, preliminary figures from analyst IDC have shown.
Oracle Database generated $7.3bn (£3.65bn) in sales in 2006, giving the vendor 44.4% of the $16.5bn (£8.3bn) global market. "Oracle continued to glide along in first place, bolstered by apparently broad acceptance of the 10g R2 release and the success of key options," a report by IDC analyst Carl Olofson says.
IBM, primarily through its DB2 database, generated $3.5bn (£1.75bn) in sales. While that was up 11.9% from 2005, IBM failed to keep pace with Oracle's 14.7% growth, which also outpaced the overall market's 14.3% rate of year on year growth. IBM's market share fell slightly, from 21.6% in 2005 to 21.2% last year.
Microsoft, in third place, enjoyed the fastest rate of growth, 25%, giving it a total of $3.1bn (£1.55bn) in sales. It held 18.6% of the market at the end of the year.
Fourth placed Sybase and fifth placed NCR Teradata also grew, albeit at a pace slower than the market as a whole.
Other vendors, including MySQL, PostGreSQL and Ingres rang up $1.6bn (£800m) in sales last year but saw their collective share of the market fall from 10.7% to 9.9%.
IDC noted that the revenue figures include core products but not the features vendors sell as separate options, making like-for-like comparisons difficult.
