It's home page is http://www.mysql.com/

Interesting Note its licensing is a thorn in the side of some developers. Cynics would say that this is their way of getting you to buy a commercial license; personally, I'm not convinced that this is just a legalistic misunderstanding (on their part) of what the Free/Open Source Software movement is trying to accomplish. Either way, read on... the following is taken from http://www.mysql.com/company/legal/licensing/

• The Commercial License, which allows you to provide commercial software licenses to your customers or distribute MySQL-based applications. This is for organizations that do not want to release the source code for their applications as open source / free software; in other words they do not want to comply with the GNU General Public License (GPL). For more detail on the Commercial non-GPL License, click here. Or, if you want more information on pricing, click here.

• For those developing open source applications, the Open Source License allows you to offer your software under an open source / free software license to all who wish to use, modify, and distribute it freely. The Open Source License allows you to use the software at no charge under the condition that if you use MySQL in an application you redistribute, the complete source code for your application must be available and freely redistributable under reasonable conditions. MySQL AB bases its interpretation of the GPL on the Free Software Foundation's Frequently Asked Questions. For more information on MySQL's Open Source License, click here.

So, the short story is that, since we aren't paying for the use of MySQL here in the Center, we're required to distribute the complete source code for our applications. Hmm.
