Multi-Version Concurrency Control
CONCURRENCY CONTROL METHOD COMMONLY USED BY DATABASE MANAGEMENT SYSTEMS
Multi-Version Concurrency Control
<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.
