This is the new Gartner magic quadrant for operational (transnational, OLTP) DBMS (Oct., 2015). It appears that Microsoft’s hard work and licensing structure pay off to beat Oracle. I was hoping to see the rankings of big data vendors, such as MapR, Cloudera, Hortonworks, and others, to be a lot higher but they are not. Maybe, big data applications are still limited to a few big name companies such as Google, Amazon, or Netflix, but not the majority of businesses. And, those big data businesses are more related to streaming and internet searches, less about point-of-sales and logistics operations. Or, maybe, traditional DBMS is already sufficient to meet most business needs with reasonable cost.
