Gartner released it’s 2011 Magic Quadrant for Business Intelligence Platforms, and Oracle apparently is sponsoring it for the public.
We have to obvious suspects in the leaders quadrant: Oracle, IBM, Microsoft and SAP, as well as a few smaller folks. Most of the remaining vendors are in the niche players quadrant, there are no visionaries and just two in the challengers quadrant.
The market according to Gartner appears to be mature, and most vendors have found a good (or should I say: boring?) balance between vision and execution.
