PostgreSQL, also called PostgreSQL, is one of the most popular SQL database management systems (DBMS) ever.
It is Open Source, free for personal and commercial use, and it has a long history that started in 1996, building on top of other software that dates back to the 1980’s.
PostgreSQL is a really complete and full-featured general purpose relational database.
It provides support for most of the SQL standard, and also builds on top of it its unique set of features, to provide us a great tool.
You can find the project homepage at https://www.postgresql.org.
We can interact with a PostgreSQL database using many different programming languages. Internally, being a relational database we’ll use SQL to insert, query and manipulate the data.
