Good and Bad  2007-09-12
This book is a good introduction to data warehousing. However, the style is remarkably bad. It is very repetitious, poorly organized overall, occasionally self-contradictory, and jam-packed with cartoon-like line drawings that seldom add clarity to the discussion. The book easily could be reduced from 500 pages to 200 pages without losing any information, and with an improvement in readability.
BI for smarties  2007-08-23
In my opinion Kimball vs Inmon is not a war of religion, they both have pro and cons in different situation. I believe people seriously interested in BI should read the book and take several advices from it. There are situation in which an Inmon design is good, there are some in which it isn't BUT to be able to judge you need to know both an be able to decide based on the customer's necessity.
The pictures in the book are really ugly and useless, nevertheless the concepts are clearly stated and easily understandable. If I have to say something wrong about it is that you need to already know what a BI system is in order to get the most out of the book. It is not for newcomers but it is definetely a good book on BI.
Review of Data Warehouse Tools  2006-11-02
Received in a timely manner, in good condition, and it is very useful. Thx.
The (im)practical approach to DW design  2005-08-28
If you work for a large corporation which has millions of $ to spend on DW projects, maybe you should look at this book and even consider some of the ideas that it contains.
But if you need to develop a data warehouse using limited resources and within a certain timeframe, your time will better used reading other books, because following the Inmon approach will lead you to an unnecessary complicated and expensive design.
I found that the arguments used by Inmon to demonstrate the limits of the dimensional approach are not convincing at all. For example, at page 142 he says "Because there is a different data structure for each data mart, making any data mart into a data warehouse doesn't make sense."
Having personally implemented several data warehouses using the "conformed dimensions" approach, I can guarantee that it worked and produced a very elegant and clean data model.
Everything you wanted to know about building a Data Warehouse 2005-08-02
An extremely well written book that not only is wide in scope but also tells the story - shows how and why the data warehouse evolved. The author details the subject thoroughly, points out the pitfalls, explains the proper methodology for success. The illustrations are terrific! This is a must have for anyone involved in Data Warehousing projects.
