Mastering Data Warehouse Aggregates: Solutions for Star Schema Performance

Acknowledgments

Thank you to everyone who read my first book, Data Warehouse Design Solutions, which I wrote with Mike Venerable. The positive feedback we received from around the world was unexpected, and most appreciated. Without your warm reception, I doubt that the current volume would have come to pass.

This book would not have been possible without Ralph Kimball. The value of his contribution to the data warehousing world cannot be understated. He has established a practical and powerful approach to data warehousing and provided terminology and principles for dimensional modeling that are used throughout the industry. I am deeply grateful for Ralph's continued support and encouragement, without which neither this nor my previous book would have been written.

I thank everyone at Wiley who contributed to this effort. Bob Elliott was a pleasure to work with and provided constructive criticism that was instrumental in shaping this book. Brian Herrmann made the writing process as painless as possible. I also thank the anonymous reviewers of my original outline, whose comments made this a better book.

Thanks also to Jim Hadley, who put in long hours reviewing drafts of this book. Through his detailed comments and advice, he made a substantial contribution to this effort. His continuing encouragement got me through several rough spots.

I am grateful to the customers and colleagues with whom I have worked over the years. The opportunity to learn from one another enriches us all. ...
