I chose this book, because I needed to get some background on BI fairly quickly. It satisfied that need very well. It is quite well-written and some parts read more like a story, which is quite the opposite of the "just the facts, ma'am" approach of Kimball and his associates. (That is not a stab at Kimball. I am a big fan and I believe they have so much to say that they don't really have the space to make it story-like. Kimball has a completely different goal with his books -- but this is not a Kimball-review.)
At the start, the book introduces us to the Director of Imports at a gift and novelty wholesale company. Her initiative of selling a certain item didn't work so well, and we get to know the steps she has taken to analyze the data to find out what happened. Along the way, we are introduced to many Data Warehousing / Business Intelligence (DW/BI) concepts.
After the story, some basic DW/BI terms are explained in more detail. The authors explain quite well where they fit in the process of getting from mounds of static data, to a useable set of data for analytical purposes, which they call the BI Roadmap.
The book contains five case studies of a few pages each, which help fix the process of implementation.
If you know nothing about DW/BI and you quickly need a framework on which to hang whatever knowledge you gain elsewhere, I'd say this is a great start. Also, if you've implemented a DW/BI system and failed, this may help get you back to your roots. However, if you've read a lot of in-depth material and maybe have an implementation or two (successful) under your belt, this will only serve as a relaxing read; you won't gain much new knowledge from it.
I give it 5 stars, because it does what I think it attempts to do. It gives you background knowledge and a framework; it does not attempt to be an encyclopaedic work and desk reference, like Kimball's books are. Therefore it reads in a fraction of the time it would take to read Kimball. If background is what you're looking for, enjoy.
