MySQL

Market position

MySQL is described as the world's most popular open source database in its own repository metadata and is widely used across web applications and major websites including Facebook, Flickr, MediaWiki, Twitter and YouTube, as well as CMS platforms such as Drupal, Joomla, phpBB and WordPress [3][7]. In 2006 MySQL was estimated to hold about a 33% share of the database market by install base but only about 0.2% by revenue, in a market then worth roughly $15 billion; Oracle CEO Larry Ellison at the time characterized MySQL as "a tiny company" with revenue between $30 million and $40 million against Oracle's $15 billion [6]. Direct competition includes MariaDB, the fork created by co-founder Widenius, which Oracle addresses with migration material [5][7][0].

Public sources cite MySQL's combination of open-source availability under the GPL with commercial licensing and enterprise support, its breadth of supported operating systems, and its long-standing position in the LAMP stack and among large web properties [7][2]. Reviewers quoted by Wikipedia describe it as performing "extremely well in the average case", with strong developer interfaces and documentation, and as a fast, stable, multi-user, multi-threaded SQL server [7]. Third-party teaching material characterizes it as fast, reliable, scalable and easy to use for both small and large applications [4]. Current Oracle positioning emphasizes integrated generative AI, machine learning and vector search inside the database, and a single service (HeatWave) spanning transactions and lakehouse-scale analytics [0][2].

Technology

MySQL is an RDBMS written in C and C++, using a yacc-based SQL parser with a home-brewed lexical analyzer, and supports a broad set of operating systems including Linux, macOS, Windows, FreeBSD, Solaris, IBM AIX, HP-UX, IBM i, NetBSD, OpenBSD, OS/2 Warp, QNX and others, with an OpenVMS port [7]. It offers pluggable storage engines, historically including InnoDB from Innobase and Berkeley DB from Sleepycat [6]. MySQL 5 added stored procedures, triggers, views, cursors, distributed transactions and federated storage engines [6]. Current capabilities include MySQL NDB Cluster, a real-time transactional clustered database, and HeatWave features for query acceleration, lakehouse querying over object storage, AutoML pipelines and generative AI, plus vector search in MySQL AI [2][0]. The source tree, hosted at github.com/mysql/mysql-server, contains components for the SQL layer, storage engines, replication/binlog libraries, a router, and vector components [3].

Go-to-market

Distribution combines free open-source downloads of the Community Edition (and Early Access builds) with commercial channels: customer downloads via My Oracle Support, trials via Oracle eDelivery and developer downloads via Oracle OTN, supported by regional sales phone lines and an online contact process [2]. Developer-facing marketing includes webinars, white papers (e.g., reference architectures for security and high availability, MySQL Enterprise Edition for Government, MariaDB-to-MySQL migration), a newsletter, and free access to Enterprise Edition features for learning, development and prototyping [0][2]. Historically, MySQL AB relied first on OEM dual-licensing and then shifted toward direct enterprise subscriptions [6].

Web and application developers, open-source communities, and enterprises requiring commercial support, security and high availability, including government users [0][2][7]. A distinct segment is OEM/ISV/VAR customers embedding MySQL in products, hardware and appliances — over 2,000 such organizations according to the company site [0][1]. Historically customer counts grew from 1,000 paying customers in 2002 to 3,400 in 2005 [6].

Geography

The project originated in Sweden and Finland; MySQL AB was founded in Sweden in 1995 and added US headquarters in 2002, and by 2006 had 320 employees across 25 countries with roughly 70% working remotely [6][7]. Today MySQL is distributed by Oracle with sales contact numbers listed for the USA, Canada, Germany, France, Italy, the UK, Japan, China and India among other countries, and HeatWave is offered across multiple cloud providers [2][0].

History

The MySQL project was started in 1995 by Michael "Monty" Widenius, David Axmark and Allan Larsson, with development having begun in 1994; the first version appeared on 23 May 1995 and for its first six years the project was commercially represented by TCX, a company owned by one of the founders [6][7]. MySQL AB was founded in Sweden in 1995 [6]. The software was released under the GPL in 2000, cutting revenue sharply in the short term [6]. Mårten Mickos became CEO in 2001, US headquarters were added in 2002, and the company raised venture capital in 2001, 2003 and 2006 while growing revenue from $6.5M (2002) to $75M (2007) [6]. Oracle acquired two suppliers of MySQL storage engines — Innobase (InnoDB) in 2005 and Sleepycat (Berkeley DB) in 2006 — and Mickos confirmed in 2006 that Oracle had approached MySQL about an acquisition [6]. In January 2008, Sun Microsystems acquired MySQL AB for approximately $1 billion; Widenius and Axmark left Sun shortly afterward [5][6][7]. Widenius left in February 2009, formed Monty Program Ab, lobbied the European Commission over Oracle's pending acquisition of Sun, and forked MySQL into MariaDB [5][7]. Oracle's agreement to acquire Sun (~$7.4 billion, $9.50 per share) was announced in 2009, placing MySQL under Oracle Corporation, which continues to develop it [6][7].

Risks & controversies

MySQL AB and its founders were sued by Progress/NuSphere in 2001, and MySQL AB countersued alleging a GPL violation [6]. The 2000 move to the GPL caused an 80% revenue drop that took about a year to recover [6]. Oracle's acquisitions of Innobase (InnoDB) in 2005 and Sleepycat (Berkeley DB) in 2006 placed key MySQL storage engines under a competitor's control [6]. Oracle's pending acquisition of Sun prompted co-founder Michael Widenius in December 2009 to ask MySQL customers to lobby the European Commission over concerns about Oracle controlling MySQL, spawning a "Save MySQL" petition campaign; he subsequently forked the project into MariaDB, creating an ongoing competing distribution [5][7]. Departures of key leaders — Widenius and Axmark after the Sun deal, and CEO Mårten Mickos in 2009 — were characterized by one commentator as Sun losing the business and spiritual leaders behind MySQL's success [6]. Early Access community builds are explicitly unsupported and may contain bugs, performance issues or security vulnerabilities [2].
