MySQL is an open-source relational database management system (RDBMS) that is based on Structured Query Language (SQL) . MySQL is a client/server system that consists of a multithreaded SQL server that supports different back ends, several different client programs and libraries, administrative tools, and a wide range of application programming interfaces (APIs) . MySQL databases are relational, which means that data is organized into one or more data tables in which data may be related to each other, and these relations help structure the data. SQL is the most common standardized language used to access databases, and it is used to create, modify, and extract data from the relational database, as well as control user access to the database. MySQL is ideal for both small and large applications, and it is very fast, reliable, scalable, and easy to use. MySQL is used by many database-driven websites and applications, including Facebook, Twitter, Netflix, Airbnb, WordPress, Drupal, Joomla, and Magento.
