Version 4.0: beta from August 2002, production release March 2003 ( unions).Version 3.23: beta from June 2000, production release 22 January 2001.Version 3.21: production release 1998, from.Windows version was released on 8 January 1998 for Windows 95 and NT.Milestones Īdditional milestones in MySQL development included: By keeping the API consistent with the mSQL system, many developers were able to use MySQL instead of the (proprietarily licensed) mSQL antecedent. They created a new SQL interface, while keeping the same API as mSQL. It was initially created for personal usage from mSQL based on the low-level language ISAM, which the creators considered too slow and inflexible. Original development of MySQL by Widenius and Axmark began in 1994. MySQL was created by a Swedish company, MySQL AB, founded by Swedes David Axmark, Allan Larsson and Finland Swede Michael "Monty" Widenius. History ĭavid Axmark (left) and Michael "Monty" Widenius, founders of MySQL AB, in 2003 It has also been tested to be a "fast, stable and true multi-user, multi-threaded SQL database server". MySQL has received positive reviews, and reviewers noticed it "performs extremely well in the average case" and that the "developer interfaces are there, and the documentation (not to mention feedback in the real world via Web sites and the like) is very, very good". Additionally, a number of third party organisations exist to provide support and services. They differ in the scope of services and in price. Oracle offers paid support via its MySQL Enterprise products. Free support additionally is available in different IRC channels and forums. Support can be obtained from the official manual. They are offered under GPL version 2, or a proprietary license. The MySQL server software itself and the client libraries use dual-licensing distribution. MySQL works on many system platforms, including AIX, BSDi, FreeBSD, HP-UX, ArcaOS, eComStation, IBM i, IRIX, Linux, macOS, Microsoft Windows, NetBSD, Novell NetWare, OpenBSD, OpenSolaris, OS/2 Warp, QNX, Oracle Solaris, Symbian, SunOS, SCO OpenServer, SCO UnixWare, Sanos and Tru64.
Its SQL parser is written in yacc, but it uses a home-brewed lexical analyzer. MySQL is also used by many popular websites, including Facebook, Flickr, MediaWiki, Twitter, and YouTube. MySQL is used by many database-driven web applications, including Drupal, Joomla, phpBB, and WordPress. MySQL is a component of the LAMP web application software stack (and others), which is an acronym for Linux, Apache, MySQL, Perl/ PHP/ Python. MySQL has stand-alone clients that allow users to interact directly with a MySQL database using SQL, but more often, MySQL is used with other programs to implement applications that need relational database capability. In 2010, when Oracle acquired Sun, Widenius forked the open-source MySQL project to create MariaDB. MySQL was owned and sponsored by the Swedish company MySQL AB, which was bought by Sun Microsystems (now Oracle Corporation). MySQL is free and open-source software under the terms of the GNU General Public License, and is also available under a variety of proprietary licenses. In addition to relational databases and SQL, an RDBMS like MySQL works with an operating system to implement a relational database in a computer's storage system, manages users, allows for network access and facilitates testing database integrity and creation of backups. SQL is a language programmers use to create, modify and extract data from the relational database, as well as control user access to the database. A relational database organizes data into one or more data tables in which data may be related to each other these relations help structure the data. Its name is a combination of "My", the name of co-founder Michael Widenius's daughter My, and "SQL", the abbreviation for Structured Query Language. MySQL ( / ˌ m aɪ ˌ ɛ s ˌ k juː ˈ ɛ l/) is an open-source relational database management system (RDBMS).
