Why choose Postgresql

PostgreSQL is one of the world's most advanced open-source relational database management systems (RDBMS). It is designed to handle a wide range of workloads, from single machines to data warehouses or Web services with countless concurrent users. The main reasons for choosing PostgreSQL as your database solution are as follows:

High Compliance with SQL​

PostgreSQL is one of the best RDBMSs for ensuring compliance with the SQL standard. It includes many advanced features that other open-source RDBMSs do not support. This high compliance makes PostgreSQL interoperable, simple to migrate to, and easy to use.

Extensibility​

PostgreSQL is designed to be highly extensible. It allows custom functions to be written in various programming languages such as C++, Python, Java, etc. It also supports a variety of extensions that can add functionality like PostGIS for geospatial analysis, and hstore for key-value storage.

Robustness and Data Integrity​

PostgreSQL is known for its robustness and assurance of data integrity. It includes features like atomicity, consistency, isolation, and durability (ACID) properties, and supports multi-version concurrency control (MVCC). These features ensure that your data is always accurate and consistent, even in high-traffic applications.

Performance​

PostgreSQL offers high performance for a wide range of workloads. It includes optimization features like advanced indexing, full-text search, and more. It also includes support for parallel query, enabling it to execute queries more quickly by using multiple CPU cores.

Security​

PostgreSQL has a reputation for strong security. It supports a wide range of authentication methods, including Kerberos, SCRAM-SHA-256, and more. It also includes robust access controls, view-based row-level security, and mandatory access controls.

Community Support​

PostgreSQL has a vibrant and active community of developers and users. Many resources are available for support, including mailing lists, forums, and more. The community also ensures that PostgreSQL continues to evolve and improve.

In conclusion, PostgreSQL is a powerful, open-source RDBMS that offers a high degree of SQL compliance, extensibility, robustness, performance, and security. With its active community support, it continues to improve and evolve, making it an excellent choice for a wide range of applications.
