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.
