PostgresSql

PostgreSQL is the world’s most advanced open source database. Developed over 25 years by a vibrant and independent open source community, PostgreSQL was born from the same research as Oracle and DB2 and contains comparable enterprise class features such as full ACID compliance for outstanding transaction reliability and Multi-Version Concurrency Control for supporting high concurrent loads.
 
PostgreSQL supports standards such as ANSI SQL and SQL/MED (including foreign data wrappers for Oracle, MySQL, MongoDB and many others) and yet is highly extensible with support for over 12 procedural languages, GIN and GIST Indexes, Spatial data support, and multiple NoSQL like features for document (JSON) or key-value based applications.
