Gartner Inc. recently analyzed major business intelligence vendors, including Oracle, IBM, and Microsoft and declared its findings at the Business Intelligence Summit. Oracles business intelligence platform is strongly integrated with its database management system, which most of the conference attendees used. "Oracle has one of the most complete stacks, I think, that integrates well from applications, now all the way down to the disk drive," as one Gartner analyst said. Oracle also clearly has a stronghold on the DBMS market and continues to fill out its data warehouse offerings.
SQL Server was also mentioned as a pro for Microsoft, as business intelligence capabilities such as reporting and online analytical-processing data mining are being incorporated into it. However, nothing was mentioned about DB2 in the analysts report on IBM.
