Open source license vs. My. SQL Licensing. One of the most interesting features of My. SQL is the license. My. SQL is an open source project.
That is, the complete source code of My. SQL is freely available.
Since June 2. 00. GNU Public License (GPL) has been valid for My. SQL. It is thus ensured that My.
SQL will continue to be freely available in the sense of the open source idea. For commercial applications of My. SQL there is a second, commercial license available in addition to GPL. More on this later.) By submitting your personal information, you agree that Tech. Target and its partners may contact you regarding relevant content, products and special offers. You also agree that your personal information may be transferred and processed in the United States, and that you have read and agree to the Terms of Use and the Privacy Policy.
Rights and Duties with Respect to the GPLOpen source is often incorrectly interpreted to mean "without cost." It is indeed true that GPL software can be used without payment of fees, provided that one adheres to certain conditions. However, the open source idea goes much further: Since the source code is freely available, when there are problems, you are not at the mercy of a software vendor. When problems arise, you can perhaps attempt to repair the problem yourself or to implement features that are lacking. Furthermore, you can appeal to the developers' group for help. You can be certain that the program code has been read by many developers and does not contain any unsavory surprises (such as so- called back doors such as the database system Interbase had for many years, whereby access to every Interbase database was possible via a hard- coded password). You are permitted to alter GPL products, and indeed sell the resulting new programs. At the end of this list of GPL merits there are a few demerits (for commercial applications).
If you wish to use a GPL program as the basis for a commercial product, you must again make your own source code freely available, in the sense of GPL, with the changes made. This is seldom something that developers of commercial products wish to do. In general, then, every program that is derived from GPL software exists under the terms of GPL. GPL is, so to speak, transmitted.)Tip: Further information on the open source idea, the full text of GPL, and explanations can be found at the following addresses: http: //www. Use of My. SQL with an Open Source License. The following list collects the different situations in which one may freely use My. SQL in the sense of GPL: My.
SQL can be used without cost if an application is locally developed and not used commercially. It is only when the resulting solution is to be sold to customers that the question of licensing comes into play. This rule is expressed on the My. SQL home page as follows: Free use for those who never copy,modify, or distribute. My. SQL can be used freely within a web site. If you also develop a PHP application and install it with your Internet service provider, you do not have to make your PHP code freely available in the sense of GPL.
Likewise, an Internet service provider may make My. SQL available to its customers without having to pay My.
SQL license fees. Since My. SQL is running exclusively on the ISP computer, this application is considered internal.)Finally, My. SQL license can be used free of charge for all projects that themselves run under the GPL or comparable free license.

The hallmark of proprietary software licenses is that the software publisher grants the use of one or more copies of software under the end-user license agreement.
If you have developed a new free e- mail client for Linux, say, and wish to store e- mails in a My. SQL database, you may do so without further ado.)Use of My. SQL with a Commercial License. In the sense of GPL the following uses are prohibited: You may not change or extend My.
SQL (that is, the database server) or sell the new version or product thus created without simultaneously making the source code of your changes freely available. You are thus prohibited from developing a new database system based on My. SQL if you are not prepared to make your extensions freely available to the My. SQL community in the sense of GPL. It is forbidden to develop a commercial product, such as a bookkeeping program, that is geared toward My.

SQL as the database without making the code available in the open source sense. If the limitations of the GPL are not acceptable to you as a commercial developer, then you may sell your product (program) together with a commercial My. SQL license. This can prove worthwhile because My. SQL remains available to you even if you are unable or unwilling to make your code available in the sense of GPL.
The firm My. SQL offers commercial licenses for consumers (that is, purchasers of their database applications) in two formats. My. SQL Network: Here the buyer obtains the right to run one My. SQL Pro Certified Server with Inno. DB support for one year.
A server is considered to be one computer, regardless of the number of CPUs.) There is no limitation on the number of clients that can access the server. The program My. SQL Network also contains access to special compiled server versions that are said to be particularly stable, e- mail and telephone support, as well as various other services.
Updates to the My. SQL server (even for versions 4. Classic Commercial My.
SQL License: Since the introduction of the program My. SQL Network the once common normal licenses have become hard to find. Use the last link of the following list.) Classic My. SQL licenses have no time limit, but are restricted to a particular principal server version. If you have a license for version 4. The cost is quite reasonable in comparison to commercial database systems (currently $2. Inno. DB support and $5.
Inno. DB support, with a significant reduction starting at ten licenses). The advantage of the program My. SQL Network is in the additional services and the free update option. Classic licenses are cheaper, on the other hand, once the My.
SQL server has been installed and should just run. Tip: Further information on My. SQL licensing can be found at the following sites: http: //www. Commercial Licenses for Client Libraries (Connector/ODBC, Connector/J, etc.)In addition to the actual My. SQL server, the My. SQL company offers client libraries that are necessary for the development of application programs (there are additional drivers that have been developed outside of the firm My. SQL, such as the PHP driver): C- API: Application interface for C programming.
Connector/C++: Library for C++ programming. Connector/J: JDBC driver for Java programming. Connector/MXJ: J2. EE MBean driver for Java programming. Connector/NET: . NET driver primarily for programming under Windows. Connector/ODB: ODBC driver for all programming under Windows.
Like My. SQL, these drivers are available under GPL. Many My. SQL client libraries, such as the JDBC driver Connector/J, used to be available in earlier versions under LGPL (lesser Gnu public license), which implies fewer restrictions for commercial applications. The situation changed, however, with version 4. If you wish to use these drivers in commercial applications, the following rule is in force: If My.
SQL client programs access a My. SQL- licensed server, then this server license is valid for the client libraries. It is thus usually unnecessary to obtain licenses for the use of client libraries, because the client libraries are automatically included with the server license. However, if you develop and sell a commercial program but do not deliver it together with My. SQL and leave the installation of the My. SQL server and its licensing to the customer, then you must obtain licenses for the client libraries used in your program.
Explicit licensing of the client library is seen by the My. SQL company as an exception, since as a rule, the server is licensed. Commercial licensing of the client library actually represents nothing other than a protection of the My.
SQL company's commercial interests. They want to avoid the situation in which commercial developers get around having to obtain a commercial license simply by not providing the My. SQL server. The customer then loads the GPL version of the My. SQL server from the Internet and believes that all is right with the world. In such a case the My. SQL company would receive nothing for the development of a commercial My.
SQL product. Client Licenses for the PHP Project, F(L)OSS Exception. Since My. SQL 4. 0, the GPL license for client libraries has led to problems with some other open source projects.
