MySQL is a widely used software application for database management. It is an open-source relational database management system (RDBMS) that allows users to store, retrieve, and manage data effectively. MySQL supports structured query language (SQL) for querying and manipulating data, making it versatile across various applications. Its robustness and scalability make it an ideal choice for both small and large enterprises. Additionally, MySQL is often paired with web applications, and it is a crucial component in many software stacks, including MERN and LAMP.
