i don't know why people here complains about lack of solutions. what's about me, i've found many useful tips & solutions inside that book. especially how to use virtual cubes and make them really 'virtual' with morphing underlying dimensions and measures extremely with mdx. more, these methods work well in the real world.
i think it's worth to spend money for that book. definitely it helped me a lot with mdx and cubes' implementation.

Very poorly written, but advanced book. Author covers wide range of topics, which are a must for anybody serious about learning MDX, but the writing style and explanations are just plain terrible. There are constant references to the topic yet to come in the subsequent chapters. Some sentences take 2-3 passes to understand. Many explanations of functions could really benefit from editor's touch (bold here, cursive there). Try to figure out the meaning of a new function when one sentence contains three words "level" and each one refers to something different. Be sure to read "Fast Track to MDX" to be sure you are ready for this one. Unfortunately this is currently the only advanced MDX book on the market.

I'm just starting to look at MDX and have a minimal background in T-SQL. This is not the book if you're in my shoes. It jumps to advanced topics much too quickly, uses terms that haven't been previously discussed, and doesn't give enough progressive examples. It just doesn't do a good job of building the basics before it starts jumping around and getting advanced.
