※ 引述《richland (百華錯拳)》之銘言：
: AB?
我只是突然很好奇 我幹麼跟你解釋這麼多...xdd
其實你必須搞懂什麼叫dual license.
至於AB很簡單
MySQL AB 是一家擁有MySQL 著作權的公司
若你要買MySQL商業授權 就要找這家公司
這家公司後來被SUN買了..
: ※ 引述《jijeng2001 (Jack)》之銘言：
: : MySQL uses a "dual licensing" business model. Under this model,
: : users may choose to use MySQL products under the free software/open
: : source GNU General Public License (commonly known as the "GPL") or
: : under a commercial license.
: : With the GPL license, MySQL is available free of charge. Users may
: : download the software for free and modify, integrate and distribute it.
: : However, GPL users must abide by the rules of the GPL, which stipulate
: : that if a MySQL-based application is redistributed, the complete source
: : code for this application must also be open and available for redistribution.
: : MySQL AB offers a commercial license for organizations that do not
: : want to release the source code for their application.
: : Commercial license customers get a commercially supported product
: : with a level of assurance from MySQL AB, without the requirement
: : that their MySQL-based software must be "open sourced".
: : MySQL is able to provide a commercial license because it has full
: : ownership of the MySQL code.
