This is a practical tutorial for Analysis Services that shows readers how to solve problems commonly encountered while designing cubes, and explains which features of Analysis Services work well and which should be avoided. The book walks through the whole cube development lifecycle, from building dimensions, cubes and calculations to tuning and moving the cube into production. This book is aimed at Analysis Services developers who already have some experience but who want to go into more detail on advanced topics, and who want to learn best practices for cube design.
A good book for refreshing your memory about SSAS, especially if it has been a while since you've worked with it. Contains also good tips on dimension properties, how to implement SCDs, etc. However, I doubt it's an expert book, maybe advanced at the most.
