PostgreSQL

PostgreSQL is an open-source relational database management system (RDBMS) that emphasizes extensibility and SQL compliance. It supports a wide range of SQL features, including complex queries, foreign keys, triggers, views, transactional integrity, and multi-version concurrency control (MVCC).

It is used for storing and managing data in various applications, from small-scale projects to large-scale enterprise systems. PostgreSQL is suitable for developers, data architects, and organizations seeking a robust, flexible, and feature-rich database solution.
