Books on Data Warehouse and Data Mining

The Data Warehouse Toolkit: The Complete Guild to Dimensional Modeling (Second Edition)
Ralph Kimball and Margy Ross
Wiley, 2004
If you only want to own a single book on data warehousing, this book should be it.  It is written by Ralph Kimball who is really the person behind dimensional modeling.  In my opinion, dimensional modeling is really the only cost-effective approach for any organization that wants to build reusable components that can be used to build data marts.  The book is an excellent overview for project managers, business analysis or data architects that are new to data warehouse development.  The first several chapters are essential to building a shared vocabulary in a data warehouse team.
