MySQL is an open source database management system. It is based on SQL, which is used for adding, removing, and modifying information in the database. A website that uses MySQL may include web pages that access information from a database. These pages are often referred to as "dynamic," meaning the content of each page is generated from a database as the page loads. Many database-driven websites that use MySQL use web scripting like PHP to access information from database. Below you will find the best MySQL web hosting companies on the internet tried and true.
