Introduction

When it comes to choosing a database management system (DBMS) for your Linux server, you may have come across two popular options: MySQL and MariaDB. Both are open-source relational databases that have gained widespread acceptance in the industry. However, they have distinct differences in terms of their features, performance, and compatibility. In this article, we will delve into the world of MySQL and MariaDB, exploring their history, key features, and use cases to help you make an informed decision for your Linux server.

History of MySQL and MariaDB

MySQL

MySQL is a popular open-source relational database management system that was first released in 1995 by a Swedish company called MySQL AB. It was founded by David Axmark, Allan Larsson, and Michael Widenius, who are still involved in the project today. MySQL gained rapid popularity in the early 2000s due to its ease of use, high performance, and support for multiple platforms. In 2008, Sun Microsystems acquired MySQL AB, and in 2010, Oracle Corporation acquired Sun Microsystems. Today, MySQL is one of the most widely used DBMS in the world, with a large community of developers and users.

MariaDB

MariaDB is a fork of MySQL that was created in 2009 by Monty Program AB, a company founded by Michael Widenius, one of the original creators of MySQL. The fork was created due to concerns about the direction of MySQL under Oracle's ownership. MariaDB aims to provide a more open and community-driven alternative to MySQL, with a focus on innovation and compatibility. Today, MariaDB is a popular choice for many organizations, including Facebook, Google, and Wikipedia.
