< 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 .
