MySQL is an open-source relational database management system. Its name is a combination of 'My', the name of co-founder Michael Widenius's daughter, and 'SQL', the abbreviation for Structured Query Language. MySQL is developed, distributed, and supported by Oracle Corporation. MySQL's relational model is based on tables consisting of rows and columns, with support for foreign keys, transactions, and stored procedures. It supports various storage engines including InnoDB, MyISAM, and MEMORY, allowing developers to optimize their database for different use cases. MySQL is widely used for web development, e-commerce, content management, and business intelligence applications. It is known for its reliability, performance, and ease of use, making it a popular choice for both small businesses and large enterprises. MySQL is used by millions of developers worldwide and is part of the LAMP stack, along with Linux, Apache, and PHP/Python/Perl, for building dynamic web applications.
