MySQL is an open-source relational database management system (RDBMS) used to store and manage data in the form of tables, rows, and columns. It is based on SQL (Structured Query Language), which is used to interact with the database. MySQL is widely used for web applications and software development due to its speed, reliability, and ease of use. It helps in tasks like retrieving, inserting, updating, and deleting data. MySQL supports complex queries, indexing, transactions, and security features, making it suitable for both small and large-scale applications. It is often used with programming languages like PHP, Python, and Java.
