What is Postgre SQL?
PostgreSQL, often referred to as Postgres, is an open-source, advanced relational database management system (RDBMS). It supports SQL for querying and managing data and also provides support for JSON and other non-relational data types. Known for its scalability, reliability, and extensibility, PostgreSQL is widely used for both small applications and large-scale enterprise systems. It includes features like advanced indexing, full-text search, and transactional support with ACID compliance. PostgreSQL is highly customizable and compatible with various platforms, making it popular among developers and organizations globally.
Key Features of PostgreSQL
PostgreSQL is a fully open-source database system, free to use, with a strong community supporting its development and updates.
