MySQL, the most popular Open Source SQL database management system, is
developed, distributed, and supported by MySQL AB. MySQL AB is a
commercial company, founded by the MySQL developers. It is a second
generation Open Source company that unites Open Source values and
methodology with a successful business model.
The MySQL Web site (`http://www.mysql.com/') provides the latest
information about MySQL software and MySQL AB.
* 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 Server. Since computers are very
good at handling large amounts of data, database management
systems play a central role in computing, as standalone utilities
or as parts of other applications.
* 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 SQL part of `MySQL' stands for `Structured Query
Language.' SQL is the most common standardized language used to
access databases and is defined by the ANSI/ISO SQL Standard. The
SQL standard has been evolving since 1986 and several versions
exist. In this manual, `SQL-92' refers to the standard released in
1992, `SQL:1999' refers to the standard released in 1999, and
`SQL:2003' refers to the current version of the standard. We use
the phrase `the SQL standard' to mean the current version of the
SQL Standard at any time.
* MySQL software is Open Source.
Open Source means that it is possible for anyone to use and modify
the software. Anybody can download the MySQL software from the
Internet and use it without paying anything. If you wish, you may
study the source code and change it to suit your needs. The MySQL
software uses the GPL (GNU General Public License),
`http://www.fsf.org/licenses/', 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 code into a
commercial application, you can buy a commercially licensed
version from us. See the MySQL Licensing Overview for more
information (`http://www.mysql.com/company/legal/licensing/').
* The MySQL Database Server is very fast, reliable, and easy to use.
If that is what you are looking for, you should give it a try.
MySQL Server also has a practical set of features developed in
close cooperation with our users. You can find a performance
comparison of MySQL Server with other database managers on our
benchmark page. See mysql-benchmarks.
MySQL Server 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.
Although under constant development, MySQL Server today offers a
rich and useful set of functions. Its connectivity, speed, and
security make MySQL Server highly suited for accessing databases
on the Internet.
* MySQL Server works in client/server or embedded systems.
The MySQL Database Software 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 a wide range of application programming
interfaces (APIs).
We also provide MySQL Server as an embedded multi-threaded library
that you can link into your application to get a smaller, faster,
easier-to-manage standalone product.
* A large amount of contributed MySQL software is available.
It is very likely that your favorite application or language
supports the MySQL Database Server.
The official way to pronounce `MySQL' is `My Ess Que Ell' (not `my
sequel'), but we don't mind if you pronounce it as `my sequel' or in
some other localized way.
