MySQL is
an open-source database management system that is widely used in many web
applications and other database-driven applications. It is a Structured Query
Language (SQL) database that is most commonly used with the popular
web-scripting languages such as PHP, Perl, and Python. The database engine
enables users to store and retrieve data for their applications, and it is
highly scalable and secure. MySQL is fully transactional and supports a wide
range of storage engines, from the MyISAM storage engine for smaller databases
to the InnoDB storage engine for large, mission critical databases. MySQL is
also designed to be easily managed, making it ideal for use in large scale web
applications. With its robust feature set and low cost, MySQL is an excellent
choice for web developers seeking a powerful yet lightweight relational
database solution.
