The BI Survey provides a detailed quantitative analysis of why customers buy BI tools, what they use them for, how successful they are and why they eventually abandon them. It is based on the analysis of actual experiences of some 1900 users worldwide. This year's Survey also includes analyses of how vendor, user and consultant perceptions vary. As such, it is the largest and most thorough fact-based analysis of the growing BI market. The BI Survey 7 benefits from the experience of the six previous editions of The OLAP Survey and the ability to analyze trends based on seven data sets.
