MySQL is an open-source relational database management system (RDBMS) widely used for building web-based applications. It was first released in 1995 and is now owned by Oracle Corporation. It is written in the C and C++ programming languages and is available for various platforms, including Windows, Linux, macOS, and Unix-like systems.

MySQL is a popular database management system because it is reliable, scalable, and easy to use. It supports the SQL (Structured Query Language) standard and provides a range of features for managing and manipulating data, including data types, indexes, triggers, stored procedures, and views. MySQL is also highly customizable, supporting multiple storage engines, including InnoDB, MyISAM, and Memory.

This system is widely used in web-based applications, including content management systems, e-commerce sites, and social networking sites. It is also used in many enterprise applications, including financial, healthcare, and telecommunications systems. MySQL is available in both Community and Enterprise editions, with the Community edition being free and open-source. In contrast, the Enterprise edition provides a fee for additional features and support services.
