MySQL is one of the most popular open-source relational database management systems that use SQL. It’s widely used for web applications and is known for its speed, reliability, and ease of use. Many platforms and applications, including WordPress and Facebook, rely on MySQL to manage their data efficiently.

Why Choose MySQL?

• Open Source: Free to use and widely supported.

• High Performance: Optimized for fast query execution.
