Is SQL2K8 Really a dot Release

  • Article

Over the past year or so the question "is Katmai really a dot release" has come up numerous times. Some people have also refered to it as the equivalent of a Windows Server R2 release (sort of like a super Service Pack). The justification for this characterization is often the same: they use the delta of features between SQL2K and SQL2K5 as the basis for earning the title major release. And the delta between SQL2K5 and SQL2K8 isn't as big. Is this the correct criteria? I think not.

If you remember back to when SQL2K5 was under development there was constant criticism about the time it was taking to release the product as well as criticism that there were too many features in the release. People clamored for us to cut features and get the product out the door. They said the product was simply too big and too complex. Furthermore they said nobody could possibly use all of the new features and that it created very complex upgrade scenarios.

When we set out working on what would become SQL2K8 we knew that we wanted to hit a release date under three years from the release date of SQL2K5. There was a lot of speculation and theories for why this timeline. The bottom line is the team had to prove that we knew how to develop software on a given timeline. This also meant that we had to be very deliberate in the feature set. We had to find the perfect balance between the feature set and the risk to the schedule.

A mail recently when out to the Group/Lead Program Managers containing the final rough feature list.  And let me tell you there's no doubt my mind the bump in the major version number is well deserved. Is the list as big as the SQL2K5 list? No. Nor should it be. Here's a little taste of what's in SQL2K8:

  • Policy-Based Management
