I had a pleasure to spend more than a hour installing SQLServer for evaluation purposes. Installed SQLServer 2008 for the first time. I have now 180 days to do test with AdventureWorks databases.
A couple weeks ago I went to see a presentation about SQLServer 2008 to Oracle specialists mainly presented by Marko Hotti. Nice overview about the product. There was a question from the audience about isolation levels in SQLServer. There is still a common understanding among Oracle specialist that readers block writers. There exists snapshot isolation level in SQLServer. It was presented allready in version 2005.
