This book drove me nuts. What I wanted was a technically-minded overview of SSAS; what I got was a mash-up of management-level metaphors and step-by-step walkthroughs of the IDE for building cubes.
...Which, to be fair, is probably what I should have expected, at least in the second part. It may be that this is a perfectly enlightening book for people who aren't already DBAs. (I'll keep it around in case it comes in handy as a tutorial someday.) For others out there who are DBAs, at the moment I'd recommend the book I picked up when I gave up on this one -- it's twice as long but more than twice as engaging, and unlike this "Step by Step" book is written so that familiar sections can be easily skimmed.
