PostgreSQL is an Object Relational Database Management System (ORDBMS) that uses SQL as the main command language to solve complex queries. Originally named Postgres, it is a free RDBMS that also supports JSON for extensibility and SQL compliance. In 1996, the project name was changed from Postgres to PostgreSQL to show its support towards SQL.
It is designed for large and complicated analytical processes and supports various features, including Acid Compliant, Materialized Views Temporary Tables, Geospatial data by means of an extension, Foreign Keys, User Defined Data types and more. The database is compatible with platforms like Windows, Linux, FreeBSD, macOS Server, and OpenBSD. It is flexible and has a strong community base. Also, it the first design that implemented Multi Version Concurrency Control (MVCC) features so it is the perfect solution for online banking software.
PostgreSQL server is popular solution for web projects such as Django, Node.js or Ruby on Rails, and supports PHP language. It supports synchronous and asynchronous replication and makes it easy to distribute the stored data across multiple servers for high resilience and minimal access time to critical data.
