SAP and BW Data Warehousing

5 stars (A very comprehensive publication) - This book covers SAP's transaction system and its Business Warehouse data warehouse. The SAP part, Part A, covers 32% of the book (pages 1-134). Part B, which is 68% of the book, covers BW from pages 135 through 419. While it includes a wealth of general information about both the transaction and data warehouse systems, it also contains technical information that provides very good information. In Chapter B12 (72 pages from pg 250-322), Creating and Loading InfoCubes, the step-by-step procedure is shown via screenshots. Chapter 14 (31 pages), Creating Queries with BEx, shows the step-by-step procedure for creating a query. These two chapters, covering 103 pages, alone constitute 24.5% of the whole book (and 36% of the BW part of the book). The book also covers the planning and design, which is something I found very useful. Ideally, the book should be divided into two books.

I would not suggest this book to someone, though, who might think that this book will enable one to develop into a BW developer, for which more extensive training is required. 2 stars (Basic BW Book) - This book gives some information about BW. 80% of the content is about background and peripheral information. What is ERP? How project team should be formulated, etc. 20% information is about BW. This information is very basic. It is not complete. You may want to buy electronic version. Information may be worth $6. But I would not recommend buying the "paper" book. Very ordinary book with elementary content. 5 stars (Best BW treatise available on the market today) - I jumped ahead to read Part 2 on the BW, since I am the lead for a BW implementation and that section is of utmost interest to me.
