Dini saves the accounts in scripfiles whereas in MySQL everything is online. The most important advantage of MySQL is that you can create UCP for the server as fetching the data dynamically from MySQL is easy. No load on scriptfiles as everything is online. You can edit a user data from anywhere, no need to be in the script folder. There is a lot more you can do with the users in MySQL.
And Dini cant access Offline users while Mysql can
The other thing I like of MySQL server is that you can make a system that allows you to register from the fourm/website, no need to go in game for registering. So MySQL is the best!
And also Dini is outdated use Sqllite or MySql
