Let get this straight if you are a absolute beginner to reporting services, databases and SQL this is not the book for you, but then the words `designing expert reports' in the title should hint at that.
However if you work in Management Information or with Reporting Services, get this book. Everything from Dashboards, Dynamics & Cubes to making simple lists look good.
This book goes though realistic example of where you may need a report and how to create it, with clear recipes it is easy to either work through the examples or adapt to your real world need as you go. The choice of chapters and recipes in the book make it easy to dip in and out of as you need, but is well reading though to get ideas of what you can do.
One great illustration that this book is written from a real world perspective is the acknowledgement that you may want to do something that is a bad idea i.e. updating data from a report, talking about why you would want to, what power this gives you, what the risks are and how to best to go about it. At last someone who lives in the real world!
My only gripe and it is a small one really is though this book covers Custom Report Items (CRIs), it only covers how to add existing 3rd party CRIs. Which is fine be I would love to see a clearly worked recipe of how to create one and then add that to your report.
If your still not sure check out the authors, bang "Paul Turley Reporting Services" or "Robert M. Bruckner" into your search engine of choice.
