OEMs (Original Equipment Manufacturers), ISVs (Independent Software Vendors), VARs (Value Added Resellers) and other distributors that combine and distribute commercially licensed software with MySQL software and do not market the source code of the commercially licensed software under version 2 of the GNU General Public License (the “LPG”) must enter into a commercial licensing agreement with Oracle. OEMs, SSOs and VARs can acquire commercial licenses. To purchase commercial licenses and support, please visit the control area of our website at order.mysql.com/. If you have specific licensing requirements or have limited access to the Internet, please contact our sales agents at sales@mysql.com. The MySQL software is published under the GNU General Public License (GPL), which is probably the best known open source license. The formal terms of the GPL license are available in www.gnu.org/licenses/. See also www.gnu.org/licenses/gpl-faq.html and www.gnu.org/philosophy/enforcing-gpl.html. If you need a license, you need it for every installation of MySQL software. This covers any number of processors on a computer, and there is no artificial limit for the number of customers who connect to the server in one way or another. The GPL license is contagious in that if a program is linked to a GPL program, the resulting product must also be released under GPL so as not to violate the license conditions and lose your right to fully use the GPL program. If you want to support the development of the MySQL database, even if you don`t need a commercial license formally. Buying support directly from MySQL AB is another great way to contribute to the development of MySQL software, with immediate benefits for you.

See section 1.4.1. MySQL was founded by a Swedish company, MySQL AB, founded by David Axmark, Allan Larsson and Michael “Monty” Widenius. The initial development of MySQL by Widenius and Axmark began in 1994. [22] The first version of MySQL appeared on May 23, 1995. It was originally created for personal use of mSQL based on the low-level LANGUAGE ISAM, which creators considered too slow and inflexible. They created a new SQL interface, while retaining the same API as mSQL. By keeping the API consistent with the mSQL system, many developers were able to use MySQL instead of the mSQL predecessor (duly authorized). [23] Check Out Section 1.4.3 for more information on how MySQL licenses work. See also section 1.4.4. If you use MySQL database software in conjunction with a web server, you will not need a commercial license. This is also the case when you use a commercial web server using a MySQL server, because you don`t sell an integrated version of MySQL yourself.

In this case, however, we would like you to acquire MySQL support, as MySQL software helps your business. Note that even if it does not have a commercial license for MySQL servers, an ISP should at least give its customers read access to the source of the MySQL installation, so that customers can verify that they are properly patched. The MySQL server software itself and client libraries use the distribution of dual licenses. They are offered under version 2 of GPL or a proprietary license. [18] If you distribute copies of MySQL software without providing the source code according to the GPL license. The GNU getopt library is covered by the GNU General Public License. See www.mysql.com/doc/L/G/LGPL-license.html. In October 2005, Oracle Corporation acquired OY, the Finnish company that developed the InnoDB storage engine from a third-party provider, which enables MySQL to provide features such as foreign transactions and keys. Following the acquisition, a press release from Oracle stated that contracts that supply the company`s software to mySQL AB would be renewed (and likely renegotiated) in 2006. [62] At the MySQL Users Conference in April 2006, MySQL AB issued a press release confirming that MySQL AB and Innobase OY have agreed to a “multi-year” extension of their licensing agreement.

[63] In April 2009, Oracle Corporation entered into an agreement to purchase Sun Microsystems[67] at the time a right-holder
