Acknowledgments

I'd like to thank all the various employers and customers for whom I've had the pleasure of working on their data warehousing projects, most notably Citicorp, Tele-Check, Electronic Data Systems (EDS), and 7-Eleven. I'd also like to thank the numerous people in data warehousing that I've either met and/or learned from, including Ralph Kimball and Gary Dodge. I also owe much to the other DBAs with whom I've worked on data warehousing projects, including Ted Chiang, Keith Carmichael, Terry Porter, and Gerald Townsend. Finally, I owe a lot to Paul Whitworth, the best data warehousing project manager I ever worked for. Paul, more than anyone else, permitted me the time and freedom to develop into an expert on data warehousing.

Additionally, I offer special thanks to all the people at Prentice Hall for bearing with my busy schedule and special needs for time off while writing this book.
