MySQL is an open-source database system that uses structured query language (SQL) to manage and manipulate connected databases. It is often used for web applications, data storage systems, and as a backend database. It is widely used for its reliability, speed, and ease of use.
MySQL allows for a user to build relational databases, linking tables and information to each other. This makes it easy to handle large amounts of data. MySQL is free to use and modify, making it extremely popular and creating a large community of users and developers. It can handle projects large and small, and is compatible with various operating systems. This flexibility also contributes to its popularity among developers.
