Multi-model database managers | DBMS 2 : DataBase Management System Services

From a timely Curt Monash DBMS reality check

"Multi-model database management has been around for decades. Marketers who say otherwise are being ridiculous.
Thus, “multi-model”-centric marketing is the last refuge of the incompetent. Vendors who say “We have a great DBMS, and by the way it’s multi-model (now/too)” are being smart. Vendors who say “You need a multi-model DBMS, and that’s the reason you should buy from us” are being pathetic.
Multi-logical-model data management and multi-latency-assumption data management are greatly intertwined."
