PostgreSQL is the World’s most advanced open source relational database. It has a strong reputation for its reliability, data integrity and robustness. Because of this, PostgreSQL is one of the most popular and widely used database systems in the world. Companies who use PostgreSQL include Apple, Cisco, Spotify, Fujitsu, Skype, Netflix and IMDb.

A 2024 survey of stackoverflow developers reported that one third of developers used PostgreSQL on a daily basis in their professional lives, up from 25% in 2023. In 2024 PostgreSQL was the fastest growing database for the fifth year in a row. PostgreSQL experience really is a desired skill in the tech industry.

Although this course uses PostgreSQL, the database, SQL and data analysis skills you learn will be applicable to other relational database systems such as MySQL, SQL Server and Oracle.
