1.  What Is PostgreSQL? #

+ PostgreSQL is an object-relational + database management system (ORDBMS) based on + + POSTGRES, Version 4.2, + developed at the University of California at Berkeley Computer Science + Department. POSTGRES pioneered many concepts that only became + available in some commercial database systems much later. +

+ PostgreSQL is an open-source descendant + of this original Berkeley code. It supports a large part of the SQL + standard and offers many modern features: + +

  • complex queries
  • foreign keys
  • triggers
  • updatable views
  • transactional integrity
  • multiversion concurrency control

+ + Also, PostgreSQL can be extended by the + user in many ways, for example by adding new + +

  • data types
  • functions
  • operators
  • aggregate functions
  • index methods
  • procedural languages

+

+ And because of the liberal license, + PostgreSQL can be used, modified, and + distributed by anyone free of charge for any purpose, be it + private, commercial, or academic. +
