Introduction to PostgreSQL

PostgreSQL is a powerful, open-source object-relational database system. It was first released in 1986, and since then, it has remained one of the most advanced database management systems. A strong developer community has actively maintained it for over 30 years. It’s known for its reliability, feature robustness, and performance. It’s available under the terms of the PostgreSQL License, a liberal open-source license.

PostgreSQL, being an object-relational database, can store data in objects. This allows data to be related to each other through relationships between objects rather than just through common fields. It supports both SQL for relational data and JSON for non-relational data. PostgreSQL is ACID compliant, meaning it supports transactions and maintains data integrity.
