PostgreSQL Tutorial
PostgreSQL is one of the most advanced general-purpose object-relational database management systems, and it is open-source. Being open-source software, its source code is available under PostgreSQL license, a liberal open source license. Anyone with the right skills is free to use, modify, and distribute PostgreSQL in any form.
Contemporary relational databases like MySQL, MariaDB, Apache Hive, etc all operate on the similar principle of establishing relationships among data, but PostgreSQL has additional features like table inheritance and function overloading as PostgreSQL supports the concept of Data objects.
