@subsection What Is MySQL
@cindex MySQL, defined
@cindex MySQL, introduction
MySQL, the most popular Open Source SQL database, is developed and provided
by MySQL AB. MySQL AB is a commercial company that
builds its business providing services around the MySQL database.
@xref{What is MySQL AB}.
@table @asis
@item MySQL is a database management system.
A database is a structured collection of data. It may be anything from a
simple shopping list to a picture gallery or the vast amounts of
information in a corporate network. To add, access, and process data
stored in a computer database, you need a database management system
such as MySQL. Since computers are very good at handling large
amounts of data, database management plays a central role in computing,
as stand-alone utilities, or as parts of other applications.
@cindex databases, defined
@item MySQL is a relational database management system.
A relational database stores data in separate tables rather than putting
all the data in one big storeroom. This adds speed and flexibility. The
tables are linked by defined relations making it possible to combine
data from several tables on request. The SQL part of MySQL
stands for "Structured Query Language" - the most common standardized
language used to access databases.
@cindex relational databases, defined
@cindex SQL, defined
@item MySQL is Open Source Software.
Open Source means that it is possible for anyone to use and modify.
Anybody can download MySQL from the Internet and use it
without paying anything. Anybody so inclined can study the source code
and change it to fit their needs. MySQL uses the GPL (GNU
General Public License) @uref{http://www.gnu.org}, to define what you
may and may not do with the software in different situations. If you
feel uncomfortable with the GPL or need to embed MySQL into a
commercial application you can buy a commercially licensed version from
us.
@cindex open source, defined
@cindex General Public License
@item Why use MySQL?
MySQL is very fast, reliable, and easy to use. If that is what
you are looking for, you should give it a try. MySQL also has a
practical set of features developed in close cooperation with
our users. You can find a performance comparison of MySQL
to some other database managers on our benchmark page.
@xref{MySQL Benchmarks}.
MySQL was originally developed to handle large databases
much faster than existing solutions and has been successfully used in
highly demanding production environments for several years. Though
under constant development, MySQL today offers a rich and
useful set of functions. The connectivity, speed, and security make
MySQL highly suited for accessing databases on the Internet.
@item The technical features of MySQL
For advanced technical information, see @ref{Reference}. MySQL is
a client/server system that consists of a multi-threaded SQL server
that supports different backends, several different client programs and
libraries, administrative tools, and several programming interfaces.
We also provide MySQL as a multi-threaded library which you can
link into your application to get a smaller, faster, easier to manage
product.
@item MySQL has a lot of contributed software available.
It is very likely that you will find that your favorite application or
language already supports MySQL.

The official way to pronounce MySQL is ``My Ess Que Ell'' (not

A license is required if:

You link a program, that is not free software, with code from the
MySQL server or clients that has the GPL copyright. This
happens for example when you use MySQL as an embedded server
in your applications or when you add not free extensions to the

become GPL through the GPL license that acts as a virus. By licensing

To determine whether or not you need a MySQL license when You can use the MySQL server for free under the GPL:
selling your application, you should ask whether the proper functioning
of your application is dependent on the use of MySQL and
whether you include the MySQL server with your product. There
are several cases to consider:

@item @item
It also depends on what you're doing for the client. Do you plan to
provide your client with detailed instructions on installing
MySQL with your software? Then your product may be contingent
on the use of MySQL; if so, you need to buy a license. If you
are simply tying into a database that you expect already to have been
installed by the time your software is purchased, then you probably
don't need a license.

The MySQL database is released under the GNU General Public License (GPL).
This means that anybody can use it for free under the GPL rules. However
if a company wishes to embed the database in a product, they have to buy
commercial licenses of MySQL or else release their product under GPL too.
Since MySQL AB owns the copyright of the MySQL server, we are able to sell
commercial licenses. This does not in any way affect the Open Source
commitment of MySQL AB. We also aim to offer commercial license packages
covering both the MySQL database and closely connected third party
software. Currently we have such an arrangement with the author of the
InnoDB transaction handler.
To buy commercial licenses, please visit the order section of @c FIX: picture: MySQL logo
@uref{https://order.mysql.com/}.
The MySQL dolphin logo was designed by the Finnish advertising agency
Priority in 2001. The dolphin was chosen as a suitable symbol for the
MySQL database since it is a smart, fast and lean animal, effortlessly
navigating oceans of data. We also happen to like dolphins.
@node Business Services Royalties, , Business Services Commercial licenses, MySQL AB business model and services The original MySQL logo may only be used by representatives of MySQL AB
@subsection Royalties and by those having a written agreement allowing them to do so.
The word @code{MySQL} and the MySQL dolphin logo are trademarks of
MySQL AB. These trademarks represent a significant value that the MySQL
founders have built over the years. We think it's fair that companies
wanting to get the benefit of these trademarks in their marketing
contributes to the development of the MySQL database by paying some
royalty. Also special versions of the trademarks are used as proofs
of certification in our partner programmes.
