With well over 10 million installations, MySQL is probably the most popular database management system for web servers. Developed in the mid-1990s, it’s now a mature technology that powers many of today’s most-visited Internet destinations.One reason for its success must be the fact that, like PHP, it’s free to use.

advantages, which we will explore in detail.
