Whats the difference between The OLAP Report and The BI Survey?
The OLAP Report is based on analyst opinion delivering detailed product reviews, analyses and case studies which help you to understand the products in-depth. On the other hand, The BI Survey is based on large numbers of user experiences and focuses on how products were used in the real-world and whether they were successful. The OLAP Report and The BI Survey 8 do not contain the same information. Anyone embarking on a major BI project should buy both.
