I've been looking a lot at the MSDN SSAS forums lately and noticed a lot of questions about processing, partitioning, and perspectives. I discuss some of these topics at the end of the my 90 minute presentation Introduction to SQL Server Analysis Services 2008 OLAP that I gave back in July to the OKC SQL Server Developers Group. These topics begin at minute 64:30.
I have given this presentation several times since, however, this is the only presentation that was video-taped. In addition, with many presentation slots being only 60-75 minutes, the July meeting was the only time where I had time to discuss the aforementioned topics.
I hope you find this video helpful in getting up to speed with the basics of SSAS 2008 OLAP. If you have any questions, feel free to post a comment here or go to the aforementioned MSDN SSAS forums.
