$49.99 Erik Thomsen's highly informed guide to OLAP theory and practice takes the reader on an in-depth tour of
multidimensional information systems. The Forward is an extraordinarily gripping read conveying insight into the need for OLAP tools. The ``airplane conversation" in particular, fuels
excitement with the contemplation of far reaching business intelligence solutions to be realized. The text is full of such moments. Large, complex concepts are aptly explored and described
in the first section of the book discussing functional requirements of OLAP systems. The section concludes with close and relentless attention to the limitations of spreadsheets and SQL, two
tools relied upon heavily by analysts today. Not only do we see that OLAP tools are worthy successors but they represent an exceedingly bright future for the business intelligence marketplace.
Few threadbare clichés are employed in the straight forward and plain explanation of multidimensional features and concepts. The reader grasps the point of OLAP through stark but pointed
insights offered by Thomsen's analysis of multidimensional benefits. A CD accompanies the hands-on case studies. This provides the opportunity to play with OLAP software currently available
today and includes business scenarios that are expertly plotted. Of course, this just serves to ignite more burning questions about what else is available and what future tools will provide.
Zealous observations continue through the investigation of dimensional modeling where comprehensive guidelines for OLAP products are listed. Each appendix is valuable to the readers'
comprehension of OLAP terms and standards. Particularly beneficial is a review of Codd's 18 rules or features and the OLAP Council's API. This book on OLAP theory is a perfect textbook, if there
ever was one, and is a high-energy experience requiring brains engaged. Jan Ortiz
