multi-version concurrency control

Computing Dictionary

Multi-Version Concurrency Control definition

database
(MVCC) An advanced technique for improving multi-user database performance.
The main difference between multiversion and lock models is that in MVCC locks acquired for querying (reading) data don't conflict with locks acquired for writing data and so reading never blocks writing and writing never blocks reading.
This technique is used in the free software database PostgreSQL.
