The Kimball Group Reader: Relentlessly Practical Tools for Data Warehousing and Business Intelligence

If you followed kimball articles, you may be interested to have all of them in an organized collection like a book.
Yes, Kimball published a new book based on these articles. I just could say that it is more than a collection of articles. Indeed, they provide a good description and tips about the whole data warehouse lifecycle using these articles.
I just took a look at it, and it was really facinate me to read it.

IBM Cognos 8 Report Studio Cookbook

I received a free copy of this book in order to write my standpoint on it.

I think if you are new to cognos, or if you worked with Microsoft SQL Server Reporting Services, and want to migrate to cognos this book is very nice to follow.

Indeed, it makes the learning of cognos easier by providing lots of examples which are describes with lots of pictures.

Honestly, I think if you are professional in one reporting tools, you don't need any book, and you can just surf the tool and follow the help to overcome its difficulties.

By the way, if you are not a guru on any reporting tools, or if you do not have enough time to spend on the cognos to migrate from SSRS, I strongly recommend this book.

This book is not going to introduce any concept or any sophesticated techniques on reporting. However, it provides easy to follow step by step instructions to get familiar with the IBM Cognos 8 Report Studio.
