Introduction

MySQL is (as of July 2013) the world's most widely used open-source relational database management system (RDBMS), enabling the cost-effective delivery of reliable, high-performance and scalable Web-based and embedded database applications. It is widely-used as the database component of LAMP (Linux, Apache, MySQL, Perl/PHP/Python) web application software stack.

MySQL was developed by Michael Widenius and David Axmark in 1994. Presently MySQL is maintained by Oracle (formerly Sun, formerly MySQL AB).

MySQL tutorial of w3resource is a comprehensive tutorial to learn MySQL(5.6). We have hundreds of examples covered, often with PHP code. This helps you to learn how to create PHP-MySQL based web applications.

 

What is MySQL

    MySQL is a database management system.
    MySQL databases are relational.
    MySQL software is Open Source.
    The MySQL Database Server is fast, reliable, scalable, and easy to use.
    MySQL Server works in client/server or embedded systems.
    Initial release : 23 May 1995
    Current stable release : 5.6.13 / 30 July 2013
    Written in : C, C++
    Operating system : Cross-platform
    Available in : English
    License of MySQL is available under GNU General Public License (version 2) or proprietary EULA.
    MySQL reduces the Total Cost of Ownership (TCO)

 

        Reducing database licensing costs by over 90%
        Cutting systems downtime by 60%
        Lowering hardware expenditure by 70%
        Reducing administration, engineering and support costs by up to 50%

 
MySQL Editions

There are five types MySQL editions.

    MySQL Enterprise Edition : This edition includes the most comprehensive set of advanced features, management tools and technical support to achieve the highest levels of MySQL scalability, security, reliability, and uptime.
    MySQL Standard Edition : This edition enables you to deliver high performance and scalable Online Transaction Processing (OLTP) applications. It provides the ease of use that has made MySQL famous along with industrial-strength performance and reliability.
    MySQL Classic Edition : This edition is the ideal embedded database for ISVs, OEMs and VARs developing read-intensive applications using the MyISAM storage engine.
    MySQL Cluster CGE : MySQL Cluster is a scalable, real-time, ACID-compliant database, combining 5 x 9s availability and open source technology. With a distributed, multi-master architecture and no single point of failure, MySQL Cluster scales horizontally on commodity hardware accessed via SQL and NoSQL APIs.
    MySQL Embedded (OEM/ISV) : MySQL Database is a full-featured, zero-administration database that more than 3000 ISVs, OEMs, and VARs rely on to bring their products to market faster and make them more competitive.

 
Who uses MySQL

    Some of the most visited websites like Flickr, Facebook, Wikipedia, Google (not for search), YouTube.

Some of the widely used MySQL front ends (tools for managing MySQL)

The MySQL GUI Tools Bundle is a cross-platform open source suite of desktop applications, building and manipulating the data within MySQL databases Development on the GUI Tools bundle has stopped, The GUI Tools bundle has been replaced by MySQL Workbench with the beta releases of MySQL Workbench 5.2. Currently MySQL Workbench Team are working on Version 6.0. The first public beta, labeled version 6.0.2, was released on June 14, 2013.
There are lot of third-party free and proprietary graphical administration applications available that integrate with MySQL and users to work with database. Here are some third-party tools for managing MySQL :

    Cross Platform.
    Unicode support
    ACID compliance
    Stored procedures
    Triggers
    Cursors
    Views
    Information schema
    Strict mode (ensures MySQL does not truncate or otherwise modify data to conform to an underlying data type, when an incompatible value is inserted into that type)
    Independent storage engines
    Transactions with the InnoDB and NDB Cluster storage engines; savepoints with InnoDB
    SSL support
    Query caching
    Sub-SELECTs (i.e. nested SELECTs)

    Full-text indexing and searching using MyISAM engine
    Embedded database library
    Shared-nothing clustering through MySQL Cluster
    Support for hotbackup
    Multiple storage engines, allowing one to choose the one that is most effective for each table in the application
