Query: Excellent book out of the Toronto Lab

This book is the best book published on DB2 out of the Toronto Lab. Although it doesn't have the flair you can get with a book written by a consultant, The authors provide much more useful information that what you usually find in a book out of the developemnt lab. Usually, they just tell the party line. The authors have broken that mold and have done a really excellent job on new SQL snapshot functions. I'm building my snapshot repository as I write this. I use this book and Gunning's for all my DB2 needs. Boy and I a happy camper with these two books on my deskstop. I have to keep them from disappearing. I rated this 4 stars as it still had the company line to some extent. Great book though.
