MySQL AB was aSwedish software company founded in 1995. It was acquired bySun Microsystems in 2008,^[1] Sun was in turn acquired byOracle Corporation in 2010. MySQL AB is the creator ofMySQL, arelational database management system, as well as related products such asMySQL Cluster. The company was dually headquartered inUppsala,Sweden, andCupertino,California, with offices in other countries (France (Paris),Germany (Munich),Ireland (Dublin),Italy (Milan), andJapan (Tokyo)).

MySQLAB had 400 employees in 25 countries,^[2] andOpen-source model companies. Around 70% of the employees wereremote workers.^[3]

Together withLinux,Apache, andPHP, the MySQL Server forms one of the building blocks of theLAMP technology stack. The company claimed over 5 million MySQL installations and over 10 million product downloads in 2004.

MySQL AB representatives are commonly cited as champions of what they claim to be a "second generation" of open source companies.^{[citation needed]} The revenues of both first and second generation open source companies usually derive from selling support, consulting services, and training for their products. What generally distinguishes this "second generation" of companies, such as MySQL AB andTrolltech, from earlier "open source"business models isdual licensing — the software is supplied under an open source license, but traditional software licences are also sold by the company that owns the software. As an example, MySQL AB makes MySQL available under theGPL at no charge, but sells it under other more traditional licenses to clients who do not find the GPL to be ideal for their purposes, such as inclusion of MySQL AB technology in a closed source product.

Other sources of revenue for MySQL AB were providing support and consulting, as well as training and certification for MySQL Server. Together with some additional services, MySQL also provided a subscription-based product calledMySQL Enterprise, which is also resold by other companies such asDell,HP, andNovell.
