I order a steak not a hamburger! I immediately associated with the conceptual - high level portion - of the book which covered: building the data warehouse team, managing the data warehouse project, the data warehouse design (very important chapters outlining usage of the star schema), and implementation of the data mart. I found the first half of the book to make alot of sense. Having a Masters of Oracle DBA, I found the physical database chapters on (partitioning and tuning valuable). However, OLAP chapters seemed too sketchy. I would have preferred an in depth discussion of installing and running the Oracle Express Server (Multidimensional database) , integrating express objects with Visual Basic or Forms, and connecting Discoverer to the Multidimensional Database, as subject matter. I found the OLAP section discussing Oracle Discoverer to narrow. The chapters covering Oracle Discoverer administration significantly less through than the Oracle Tutorial Documentation. Here my questions to the author: What about building item hierarchies, creating cross-tables, or cross-table master detail reports, introduction to Discover filters, and security -> Oracle Book explaining Oracle Products. Bottom line, I think the author missed the boat by igoring the significance of multidimensional databases and how to interface with them using oracle products.
