A main memory database system (MMDB) is a database management system that primarily stores data/records on main memory (RAM). In case of disk based database system, data is stored on the secondary storage devices like disk. Main memory databases are more than 10 times faster than disk based databases because the MMDB does not have to perform disk I/O to update or query its data.
