Is there a comparison study/article on the popular BI tools - Business Objects, Microstrategy, Cognos, Crystal and Brio?
Les Barbusinski’s Answer: Yes. There was an excellent survey published in July 2001 that is still very relevant. It was titled "The OLAP Survey" and was authored by Nigel Pendse. You can purchase it directly on the Web at http://www.survey.com/reports/olap or call the market research company, Survey.com, directly at (408) 907-0001.
The article contrasts ROLAP vs. MOLAP vs. DOLAP tools and ranks most of the major BI tools for a variety of characteristics such as market penetration, suitability to task, Web deployments, percentage of purchases that end up as shelfware, customer loyalty to the product, success rates, problems encountered, etc. The only weaknesses in the article is that it did not survey Informatica’s new BI offering (it was released after the study) and the incomplete results on Microsoft’s BI offering (because it was released just as the survey started).
