To my taste, the most glaring mis-rankings in the 2012 Gartner Magic Quadrant for Data Warehouse Database Management are that it is too positive on Kognitio and too negative on Infobright. Secondarily, it is too negative on HP Vertica, and too positive on ParAccel and Actian/VectorWise.
Some good commentary. Find Gartner’s doc here.
