Reader Reviews
This review is from: OLAP Solutions: Building Multidimensional Information Systems (Paperback)
Even though I had been familiar with OLAP concepts before I bought this book, I enjoyed reading it and recommend it to anyone seriously interested in OLAP. You will learn the history of OLAP and why traditional tools like SQL and spreadsheets are not very well suited for analysis that multidimensional tools are capable of performing. There are two comprehensive chapters on basic multidimensional features like dimensions, hierarchies, attributes and so on for those who are not familiar with them yet. There are more chapters describing some advanced features like joining cubes, visualization, formulas. Sparsity problems are taken into consideration as well as storage options for multidimensional data. There are several business cases for OLAP application, but, unfortunately, as other reviewers have already noticed the software which goes with the book does not work properly, so I just skimmed throuth the chapters where the use of the software was described. For me it was not the main part because I had already had some experience with OLAP tools before. The author destinguishes clearly between data warehousing and OLAP which some people sometimes fail to do. I liked also the last chapter where the author gives some guidelines on how to evaliate OLAP tools, which may be very helpful for those who have not made their minds yet about what tool to use in their project. Although there is some outdated material in the book, it without a doubt deserves its five stars.
