Database Server MySQL Introduction
MySQL is an open-source small-scale associated database management system. The developer is MySQL AB in Sweden. Currently, MySQL is widely used in small and medium websites on the Internet. Because of its small size, fast speed, and low total cost of ownership, especially the open source code, many small and medium websites have chosen MySQL as their website database to reduce their total cost of ownership.
