Let me start by saying that the Kimball Group is widely respected as being the best there is when it comes to dimensional modelling. The book gets off to an excellent start and I found myself smiling in acknowledgement as the authors shared some of their experiences. The Kimball model is widely referenced throughout the book and this makes complete sense. It really does encapsulate what the subject is about.
So why then just two stars? Let me illustrate by defining how to connect a hosepipe! I would suggest:
1. You'll need a supply of water, hose pipe and tap
2. Connect the pipe to the tap
3. Turn on water
The Kimball way:
1. You'll need water (refer to step 2), hosepipe(refer to step 3) and tap (refer to step 4)
2. Refer to diagram 1 to determine if your water pressure is correct. You'll need to also reference this to your geography as the water may be too hard (in which case you will need to add a softener) or too soft (in which case you'll also need one of a variety of available additives). This is discussed in detail in chapter 2.
3. The hosepipe must be of a sturdy material- we recommend (insert list of long technical names here), given the environmental constraints and delimiters (insert as much nonsense jargon here as possible) that you face on your project. You'll also need to consider how wide and how long your hosepipe is- as this can drastically affect pressure/ flow rate. Please refer to Chapter 3 for a detailed discussion.
4......and so on and on and on and on.
As a consequence the book (and I would suggest the whole Kimball approach) becomes an impractical and unneccessary technical bore.
A hugely disappointing book on a subject that I feel passionately about. This book encapsulates why Business Intelligence still has so far to go to win over hearts and minds.
