Paul Larson | Justin Levandoski. Microsoft. 9/9/2016. MM-DB Tutorial VLDB 2016. 1. Tutorial Overview. Main-memory database research has been going on for a long time. Only recently do we have a number of general-purpose commercial main-memory databases. Managed jointly by CPU hardware and the operating system (OS). Programs share main memory.
