Facebook, Ebay, Amazon, Twitter, Wikipedia and Google. These are just some of the major sites where MySQL, the world’s most widely used open source relational database, is used. At our Cleveland website design firm, our developers love MySQL for its high-speed performance, strong data protection and strength under pressure. MySQL is open source, meaning no pricey licensing fees and an unrivaled depth of public information on the platform. It is the logical choice to power most website databases.
