There's more to data warehousing than you think, so start right here!
You don't need a forklift to work with a data warehouse, but you do need a hefty load of know-how to make wise decisions when setting one up. Data is probably your company's most important asset, so your data warehouse should serve your needs. Here's how to understand, develop, implement, and use data warehouses, plus a sneak peek into their future.

The intelligent view — see how business intelligence and data warehousing work together
Ask the right questions — explore data mining and learn to find what you need

Keep the user in mind — involve your users in defining business needs through testing, and learn how to get valuable feedback
Fix or replace? — learn how to review and upgrade existing data storage to make it serve your needs
Buyer beware — be prepared when dealing with data warehousing product vendors

You will get introduced to the nuts and bolts of the Data Warehouse-concept, and a strategy from decision to implementation and maintenance.
The book will introduce you to several DW-vendors, but does not go into a specific vendors products.
After this book I read Business Intelligence for Dummies, and I was afraid there would be a lot of overlap between the two, but I was happily surprised that wasn't the case. I can recommend both of them for anyone who is looking for a fast-track introduction to DW and BI.
As other reviewers has pointed out, this book isn't the end of the line, but we already knew that. If you start from scratch you will have plenty of information to keep and reading other books, getting your feet wet. If you start from zero (or even beyond that) I can promise you'll find lot of interesting information in this book.
RECOMMENDATIONS: If you are a business person trying to understand what your computer people are talking about re data warehouses, data marts or business intelligence, this is a good starting point.
But, if you are an IT/IS/computer person, skip this book and read Ralph Kimball's "Data Warehouse Toolkit", then graduate to his "Data Warehouse Lifecycle Toolkit" (covers many more aspects), and Bill Inmon's "Corp Information Factory". These 3 books, and a DBMS specific book (e.g. "Oracle 8i Data Warehousing") will be all you need for your first few projects.
This book reads like a series of columns about data warehousing. Most of the discussions are okay but somewhat on the superficial side. The author is at his best when he discusses the people side of data warehousing - especially the political issues.
If you do not want to get deeply involved in the technical aspects of the subject, W.H. Inmon and Vidette Poe provide more easily read and more penetrating introductions to data warehousing.
