MySQL is a widely used open-source relational database management system, and is a popular choice of database for use in web applications.
A relational database stores data in separate tables rather than putting all the data in one area. These tables are linked by defined relations, making it possible to combine data from several tables upon request, without having to access all the data each time you make a request.
Using a relational database management system (or RDMS) means that you can add, access, and process the data stored in your database easily. MySQL uses SQL – Structured Query Language – to access the data inside its tables.
MySQL is an essential aspect of many content management systems and other web-based applications, such as WordPress, Joomla!, phpBB, and osCommerce. MySQL is also an open source database solution, meaning that it is possible for anyone to use and modify the software as needed.
