Main memory database

From Wikipedia, the free encyclopedia

A main memory database system is a database management system that mainly relies on main memory for data storage. Due to the characteristics of random access memory, these databases can offer a significant performance advantage over hard drive-based databases. However, main memory database systems only guarantee ACID properties as long as a stable power supply is present, as they generally rely on volatile memory devices, which lose all stored information during power drops.
