MySQL
MySQL is an open-source relational database management system (RDBMS) originally developed by MySQL AB, founded in 1995 by David Axmark, Allan Larsson, and Michael Widenius.
Profile
MySQL provides an open-source relational database management system used for storing, organizing, and retrieving data in web applications, enterprise software, and cloud services.
MySQL is an open-source relational database management system (RDBMS) originally developed by MySQL AB, founded in 1995 by David Axmark, Allan Larsson, and Michael Widenius. It was acquired by Sun Microsystems in 2008 for approximately $1 billion, and subsequently became part of Oracle Corporation when Oracle acquired Sun in 2010. MySQL remains one of the most widely deployed database engines globally, powering a significant portion of the web, including high-traffic sites like Facebook, Twitter, and YouTube.
The product portfolio includes the MySQL Server (the core database), MySQL Cluster, MySQL Router, MySQL Shell, and various connectors and tools. MySQL is dual-licensed under the GPLv2 and a commercial license, with Oracle offering paid support and enterprise features. The project is maintained on GitHub (github.com/mysql/mysql-server), where the trunk branch shows active development with frequent commits, including recent work on MySQL 8.4 and 9.7 branches.
As of Oracle's fiscal Q3 2026 (ending February 2026), the company reported total revenue of $17.2 billion, up 22% year-over-year, with cloud database revenue growing 35% and multicloud database revenue surging 531% year-over-year. However, Oracle's overall financial results do not break out MySQL-specific revenue. In March 2026, Oracle reportedly laid off 20,000 to 30,000 employees globally, on top of 10,000 cuts the prior year, raising concerns about the long-term investment in MySQL development.
The MySQL community has also seen fragmentation with forks like MariaDB (led by original MySQL founder Michael Widenius) and Percona Server gaining traction. Despite this, MySQL remains the default choice for many LAMP-stack applications and is deeply embedded in enterprise and cloud environments, including Oracle's own MySQL HeatWave cloud service.
Who buys this
- Web application developers and startups using LAMP/LEMP stacks
- Enterprise IT departments running transactional workloads (e-commerce, CRM, ERP)
- Cloud platform providers offering managed database services (AWS RDS, Google Cloud SQL, Azure Database for MySQL)
- SaaS companies needing a scalable, ACID-compliant database for multi-tenant architectures
- Telecommunications and media companies handling high-volume read/write operations
Strengths and what to watch
Strengths
- Massive installed base and ecosystem: MySQL is the default database for millions of web applications, with extensive documentation, community support, and third-party tooling.
- Strong performance and reliability for OLTP workloads, particularly with InnoDB storage engine, supporting ACID transactions, row-level locking, and crash recovery.
- Oracle's continued investment in MySQL HeatWave, a cloud-native service that integrates in-memory query acceleration, machine learning, and auto-scaling, driving 35% year-over-year cloud database revenue growth in Q3 FY2026.
Watch for
- Oracle's massive layoffs (20,000–30,000 jobs in March 2026) could reduce MySQL engineering headcount and slow down feature development and bug fixes, as seen in past Oracle acquisitions.
- Growing competition from forks like MariaDB and Percona Server, as well as from cloud-native databases like Amazon Aurora and Google Spanner, which offer better scalability and lower operational overhead.
- MySQL's licensing complexity and Oracle's dual-license model can create friction for open-source contributors and commercial users, particularly around GPL compliance and patent protection.

Frequently Asked Questions
What is MySQL and what is it used for?
MySQL is an open-source relational database management system (RDBMS) used for storing, organizing, and retrieving data in web applications, enterprise software, and cloud services. It powers many high-traffic sites like Facebook and YouTube.
Who owns MySQL and how did Oracle acquire it?
MySQL was originally developed by MySQL AB, founded in 1995. Sun Microsystems acquired MySQL AB in 2008 for about $1 billion. Oracle then acquired Sun Microsystems in 2010, making MySQL part of Oracle's product portfolio.
What are the main features of MySQL database?
MySQL offers ACID compliance, row-level locking, and crash recovery through the InnoDB storage engine. It includes tools like MySQL Server, MySQL Cluster, MySQL Router, and MySQL Shell. It is dual-licensed under GPLv2 and a commercial license.
Is MySQL still a good choice for web applications in 2026?
MySQL remains the default database for millions of LAMP-stack web applications. However, Oracle's massive layoffs in March 2026 and growing competition from forks like MariaDB and cloud-native databases raise concerns about future development and support.
What is MySQL HeatWave and how does it perform?
MySQL HeatWave is Oracle's cloud-native service that integrates in-memory query acceleration, machine learning, and auto-scaling. In Oracle's fiscal Q3 2026, cloud database revenue grew 35% year-over-year, driven partly by HeatWave adoption.
How do MySQL forks like MariaDB compare to the original?
MariaDB, led by original MySQL founder Michael Widenius, and Percona Server are popular forks that offer similar functionality. They have gained traction due to concerns about Oracle's stewardship, licensing complexity, and potential slowdown in MySQL development after layoffs.
