PostgreSQL is an advanced, enterprise class open source Object-Relational Database Management System (ORDBMS). Its is a relational database that supports both SQL (relational) and JSON (non-relational) querying.

PostgreSQL possesses robust feature sets including Multi-Version Concurrency Control (MVCC), point in time recovery, granular access controls, tablespaces, asynchronous replication, nested transactions, online/hot backups, a refined query planner/optimizer, and write ahead logging. It supports international character sets, multi-byte character encodings, Unicode, and it is locale-aware for sorting, case-sensitivity, and formatting. PostgreSQL is highly scalable both in the quantity of data it can manage and in the number of concurrent users it can accommodate.
