The Birth of MySQL

• Year: 1995
• Created By: Michael Widenius, David Axmark, and Allan Larsson
• Organization: MySQL AB (Sweden/Finland)

MySQL was initially developed to fill the need for a fast and lightweight SQL-based database that could work efficiently for web applications and embedded systems. The name “MySQL” is derived from Michael Widenius’ daughter’s name, “My”, and SQL.

MySQL 1.x to 3.x – The Early Days

MySQL quickly gained popularity due to its performance and ease of use, making it a staple for developers working with PHP and the LAMP stack.

MySQL 4.x to 5.x – Enter the Enterprise World

MySQL 4.0 (2003)

• Query caching, SSL support, binary logs for replication
• Widely adopted in early enterprise applications

MySQL 4.1 (2004)

• Added subqueries, UNION, collations, and prepared statements

MySQL 5.0 (2005)

MySQL 5.x was a turning point—making the database more enterprise-capable and powerful.

Sun & Oracle Take Over

☀️ Sun Microsystems Acquisition (2008)

• Sun Microsystems acquired MySQL AB for $1 billion
• Sun promised to continue MySQL’s development as open source

Oracle Acquisition (2010)

• Oracle Corporation acquired Sun Microsystems, and thus, MySQL
• Concerns rose over MySQL’s future due to Oracle’s competing product (Oracle Database)
• This led to the birth of community forks like MariaDB and Percona
