What is MySQL?

MySQL is a multi-threaded SQL database server that supports multiple simultaneous users. SQL (Structured Query Language) is the most popular database language today. MySQL is a client / server application that consists of a server (mysqld) and many different client applications.

MySQL is available under the GNU General Public License (GPL). Different browser-based applications like phpMyAdmin and MySQL AB's own Query Browser provides a user interface that makes it easier to update MySQL without knowledge of SQL.

MySQL is built around different databases on a server, where each user typically has access to a database. In MySQL, that is a relational database, you can create tables.
