Query: Must read for anyone working with SQL 7 DW

This is an excellent book. It has three detailed chapters on MDX, good descriptions on how to build data warehouses with SQL 7, a discussion on DTS, and includes an introductory chapter on OLAP for those not familiar with it. Great chapter on optimizing a SQL DW, too. My only negative comment is that I found chapter 9 wasn't that useful, and read it after I read the other chapters. I also skipped the code sample in the appendix. Everything else in the book is good. I highly recommend the book.
