Ebook: The Kimball Group Reader: Relentlessly Practical Tools for Data Warehousing and Business Intelligence

As other have stated, this is a compilation of articles written by Dr. Kimball et al spanning from the late 1990's to today. Not only is it a great resource, well organized and complete, but also an interesting history of subtle changes in thinking and approach to dimensional design.

This is the book I was waiting for. It goes much deeper into the thought process, philosphy, and art of dimensional design than any of the previous books. It is a must have for any active practitioner who wishes to gain a better understand of why things are done they way they are done.
