Query: Big On Errors And Small On Utility

The architecture overviews are good, but from there on it's full of errors and lacking the detail needed to make it useful. It has what you could loosely call "excercises" that I've gone through (step-by-step) and found many errors with. Errors that require many hours of debugging and fixing on the part of the reader. The writing is very cursory, overly broad and not detailed enough to be useful. The book often mentions that something useful CAN be done with Report Services but doesn't explain HOW to do it. Perhaps a revised edition is in order. One with more detail and with walkthroughs that have been followed, tested and confirmed accurate.
