What is MySQL?

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.
