At Oracle OpenWorld yesterday I spoke to an attendee from a global enterprise. His company is a big IBM customer and would like to standardise on DB2. To some extent it does, but there is still around 30% Oracle and significant usage of Microsoft SQL Server. Why three database platforms when they would prefer to settle on one? Applications, which in many cases are only certified for a specific database manager.
I was at MySQL Sunday earlier in the day, and asked whether he had any interest in Oracle’s open source database product. As you would expect, he said it was enough trouble maintaining three different systems; the last thing he wanted was a fourth.
