PostgreSQL
<database> /'post-gres-kyu-el/ An enhancement of the
POSTGRES database system.
PostgreSQL is an advanced
relational database management system with some object oriented approaches.
PostgreSQL is developed and distributed as
free software, and while retaining its freedom it remains technically and featurewise a worthy competitor to even the most advanced commercial alternatives.
It was also one of the first databases to offer
MVCC as opposed to
row-level locking or
table locking, thereby greatly improving multi-user performance.
PostgreSQL implements an extended subset of
ANSI SQL and runs on many platforms.
It also has interfaces to many different programming languages and database protocols, like
ODBC and
JDBC.
