# PostgreSQL

This database management system shares its popularity with MySQL. This is an object-relational DBMS where user-defined objects and table approaches are combined to build more complex data structures. Besides that, PostgreSQL has a lot of similarities with MySQL. It’s aimed at strengthening the standards of compliance and extensibility.

Consequently, it can process any workload, for both single-machine products and complex applications. Owned and developed by PostgreSQL Global Development Group, it still remains completely open-source. This DBMS is available for use with such platform systems as Microsoft, iOS, Android, and many more.
