Since MariaDB is a fork of MySQL, the database structure and indexes of MariaDB are the same as MySQL. This allows you to switch from MySQL to MariaDB without having to alter your applications since the data and data structures will not need to change.
This DBMS is an improved version of MySQL. It comes with numerous inbuilt powerful features and many usabilities, security and performance improvements that you cannot find in MySQL.
It is released with the Business Source License, which allows for all the code to be entirely open and usage under three servers to be free. When usage goes over three servers, the company using it must pay for that usage.
