PostgresQL is an object-relational database management system (ORDBMS) based on version 4.2 of POSTGRES developed by the Department of Computer Science at the University of California, Berkeley. It has now been renamed to PostgreSQL. PostgreSQL supports most SQL standards and provides many other modern features: complex queries, foreign keys, triggers, views, transaction integrity, MVCC. Similarly, PostgreSQL can be extended in many ways, for example, by adding new data types, functions, operators, aggregate functions, and indexes. Use, modify, and distribute PostgreSQL for free, whether it is for private, commercial, or academic research.
