MySQL is a globally established relational database management system (RDBMS), which is available as open source software and enables the management and organization of data through the structured query language SQL. The original development began in 1994 by Michael Widenius, David Axmark and Allan Larsson, and the first version was released on May 23, 1995. The name „MySQL“ is made up of the first name „My“ (the daughter of one of the co-founders) and the acronym „SQL“. Since 2010, MySQL has been owned by Oracle Corporation, which continues to develop it further and offers it both as an open source version under the GNU General Public License and in proprietary enterprise versions.
Architecture and functionality
MySQL is based on a client-server architecture. A client, which can be an application or a user, sends SQL queries to the MySQL server via a network. The server processes these queries, manages the databases and returns the results. The central communication language is SQL (Structured Query Language), which is used to create, read, update and delete data (CRUD operations) and define database structures.
A characteristic feature of MySQL is the support of different storage engines, which can be adapted to specific requirements. InnoDB has been the standard engine since MySQL 5.5. It offers high transaction security (ACID conformity), row-level locking and supports foreign keys. Alternatively, there is MyISAM, for example, which often enables faster read operations but does not support transactions. Choosing the right engine is crucial for the performance and data integrity of an application.
Advantages and versatile areas of application
The popularity of MySQL is based on several core advantages: It is high-performance, reliable and scalable, which is confirmed by almost 30 years of intensive use and testing in a wide variety of scenarios. The robust security architecture with differentiated user rights and support for Secure Shell (SSH) protects data effectively. MySQL is also cross-platform compatible and runs on operating systems such as Linux, macOS and Windows. The software can be used very flexibly due to its open nature and support from a large global community as well as numerous development tools and interfaces to programming languages such as PHP, Python and Java.
MySQL is an integral part of the so-called LAMP stack (Linux, Apache, MySQL, PHP/Python/Perl) and thus a mainstay of many Web applications. It serves as the primary database solution for Content management systems (CMS) like WordPress, Joomla, Drupal and TYPO3 as well as for E-commerce platforms like Magento. Numerous large online services and social networks, including Facebook, Flickr, Twitter and YouTube, use MySQL to store and manage their large amounts of data. It is also used in enterprise applications, SaaS solutions, online gaming and IoT monitoring systems.
