This is the book you must read if you want to master MDX, a language specifically designed to develop applications based on OLAP databases (particularly Microsoft Analysis Server).
And this is the book to keep as a reference guide on your desk when designing Olap solutions, as I do.
No other books go so deep into MDX, and his author is really "the MDX Guru".
However, this book is not for the total beginner, to whom "Microsoft SQL Server 2000 - Analysis Server Step by Step" by Jacobson could provide a smoother introduction to the subject. To get conceptual fundamentals for Olap I suggest Erik Thomsen's "Olap Solutions" (a new edition is coming...), and cube design techniques with Microsoft Olap can be found in "Microsoft Olap Solutions" by Spofford, Thomsen and Chase (together with some chapters on MDX which have been reworked and updated in "MDX Solutions")
