If there were a way to give 0 stars, that's what I'd rate this book. I found the previous version rather spotty in its coverage and thought that the depth was uneven from chapter to chapter. But it did contain some useful information, and I expected the same from this edition. To my considerable disappointment, this is simply the 6.5 book with search and replace of 6 with 7 and 2K with 8K. The author does not discuss the new optimizer or disk storage structures, but does include material on database devices (not a part of 7.0 storage architecture) and mirroring (not available in 7.0). The discussion of query plans is about 6.x. I am surprised that a respectable publisher like Prentice-Hall even let this out their doors (guess they needed the money) and I am even more surprised that a reputable author like Jeff Garbus lent his name to this "fleece the tourists" work.
