Selected hosting plans provide database features. MySQL and PostgreSQL are lightweight database engines designed to provide fast access to stored data. In most instances, knowledge of web development / programming is needed to implement a fully functional web-to-database interface.
You can create new databases and database credentials in your account cPanel.
StartUp and Pro plans support lightweight database usage (Start Up: 5 or less tables; Pro: 10 or less tables) while Corp and higher plans support more intensive use (Corp: 20 or less tables; higher custom server solutions: unlimited tables).
