This book is an excellent learning material to learn the MDX language. It takes you from the elementary to intermediate/advanced level.
You might have challenges installing the sample database as is common with installing some databases included in study materials.
Please follow the instructions as stated in the book BUT DELETE THE .LDF FILE FROM THE LOCATION YOU ARE ATTACHING THE DATABASE FROM. The installation process will create a new .LDF file and you should be fine from then on.
Lazy, incompetent and stupid would be the best way to describe this book. The authors/publishers are too lazy, stupid, sleazy and incompetent to even bother providing the sample databases etc. in a workable state. I have spent an entire frustrating day trying to get what these sleazy incompetents put in the book to work to even bother going any further. Don't waste your money buying this book - the online solutions do not work and they do not give a monkeys that you have spent £25 on their pathetic rubbish. DO NOT BUY!!! BUYER BEWARE - SLEAZY MICROSOFT SCAM!!!
