The Visibooks Guide to MySQL Basics
MySQL is the world's most popular open-source database program. MySQL is more like Microsoft SQL Server (a server-based database program) than Access (mainly for desktop users). With MySQL running on a server, you can easily use it for business systems or database-driven websites. Easy to use and configure, MySQL is also capable of industrial-strength applications. Depending on the computer it’s installed on, MySQL can hold several terabytes of information per table.
