MySQL AB

From Free net encyclopedia

Template:Infobox Company

MySQL AB (founded 1995) is dual headquartered in Uppsala, Sweden and Cupertino, California, USA. The company is the creator and owner of MySQL, a relational database management system.

With over 300 employees in over 25 countries (figures from January 2005), MySQL AB is one of the largest open source companies worldwide. Other known open source companies are Red Hat and JBoss Group.

Together with Linux, Apache and PHP/Perl/Python, MySQL forms one of the building blocks of the LAMP technology stack. The company claims a user base of over 5 million MySQL installations worldwide, 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. 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" consisting of companies like MySQL AB and Trolltech from earlier "open source" business models is dual licensing: while the software may be made available under the provisions of some open source license, the software is in fact owned by the for-profit companies who seek to derive revenues from selling traditional software licenses.

For instance, MySQL AB makes MySQL available under the GPL 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 (e.g. - inclusion of MySQL AB technology in a closed-source product).
