What are the differences between SQL Server, PostgreSQL, and MySQL?

• SQL Server: Developed by Microsoft, it's known for its strong integration with other

Microsoft products. It’s commonly used in enterprise environments.

• PostgreSQL: An open-source, object-relational database known for its standards

compliance, extensibility, and advanced features like support for complex queries,

JSONB, and custom data types.

• MySQL: An open-source relational database known for its speed and ease of use.

It's often used in web applications (e.g., with PHP) and is less feature-rich than

PostgreSQL but highly reliable.
