PostgreSQL is a full-featured free software Object-Relational Database Management System (ORDBMS).
PostgreSQL supports most SQL standards and offers many other modern features: complex queries, foreign keys, triggers, views, transaction integrity, and multi-version concurrency control. Also, PostgreSQL can be extended in many ways, such as by adding new Data Types, functions, operators, aggregation functions, indexing methods, and procedural languages. And because the license is flexible, anyone can freely use, modify, and distribute PostgreSQL for any purpose, whether for private, commercial, or academic research.
