PostgreSQL is a powerful and fully-featured database management system with which business owners can create object relational tables. It is an open source project that can be acquired for free and heavily focuses on elements such as extensibility and strict standard compliance. PostgreSQL is a flexible server system that can manage large workloads that are being contributed and accessed from a wide range of locations such as in a network, as well as small-scale projects like a single machine or user.

Some technical details of interest about PostgreSQL include:

  • Its MVCC (Multi-inversion concurrency control) allows fluid changes to be made to the system without cumbersome roadblocks, while maintaining the optimal level of ACID.
  • Replication, built-in binary replication is available from the 9.0 version and later.
  • It offers a wide range of indexing capabilities, including B-tree and hash indexes, as well as GIN and GiST (generalized inverted indexes and generalized search trees).
  • It uses procedural languages that make it easier for developers to expand the database.
