Introduction

MySQL and MariaDB are very similar, but there are important differences developers should know. Both are popular open-source relational database management systems widely used in PHP applications, WordPress websites, and enterprise environments.

MariaDB was created as a community-driven fork of MySQL after Oracle acquired MySQL, with the goal of remaining fully open-source while improving performance and adding advanced features.

Although MySQL and MariaDB share the same core structure and syntax, they differ in licensing, storage engines, speed, and long-term development direction. Choosing the right database can impact performance, scalability, and compatibility of your application.
