MariaDB Tutorial

MariaDB is an open-source relational database technology. It is a great alternative or drop-in replacement for MySQL.

Our tutorial will start with the basics of MariaDB such as how to retrieve and manipulate data. Then we will move to the more advanced topics such as how to create tables, functions, procedures, and triggers. We will conclude with a review of the functions that are proprietary to MariaDB.

With this tutorial, you should be on your way to becoming proficient in MariaDB and its programming language.
