They are offered under GPL version 2 [17] , or a proprietary license. Support can be obtained from the official manual. They differ in the scope of services and in price. Additionally, a number of third party organisations exist to provide support and services, including MariaDB and Percona.

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".

It was initially created for personal usage from mSQL based on the low-level language ISAM , which the creators considered too slow and inflexible.

Work on version 6 stopped after the Sun Microsystems acquisition. The decision was made to jump to version 8 as the next major version number. S District Court in Boston for "breach of contract, tortious interference with third party contracts and relationships and unfair competition". After the acquisition, an Oracle press release mentioned that the contracts that make the company's software available to MySQL AB would be due for renewal and presumably renegotiation some time in Sun's board of directors unanimously approved the deal.

It was also approved by Sun's shareholders, and by the U.

At the same time, some Free Software opinion leaders including Pamela Jones of Groklaw , Jan Wildeboer and Carlo Piana , who also acted as co-counsel in the merger regulation procedure advocated for the unconditional approval of the merger. MySQL is offered under two different editions: When using some storage engines other than the default of InnoDB, MySQL does not comply with the full SQL standard for some of the implemented functionality, including foreign key references.

Up until MySQL 5. MySQL can be built and installed manually from source code, but it is more commonly installed from a binary package unless special customizations are required. On most Linux distributions , the package management system can download and install MySQL with minimal effort, though further configuration is often required to adjust security and optimization settings.

Though MySQL began as a low-end alternative to more powerful proprietary databases, it has gradually evolved to support higher-scale needs as well. It is still most commonly used in small to medium scale single-server deployments, either as a component in a LAMP -based web application or as a standalone database server. Much of MySQL's appeal originates in its relative simplicity and ease of use, which is enabled by an ecosystem of open source tools such as phpMyAdmin.

In the medium range, MySQL can be scaled by deploying it on more powerful hardware, such as a multi-processor server with gigabytes of memory. There are, however, limits to how far performance can scale on a single server 'scaling up' , so on larger scales, multi-server MySQL 'scaling out' deployments are required to provide improved performance and reliability.

A typical high-end configuration can include a powerful master database which handles data write operations and is replicated to multiple slaves that handle all read operations. Further improvements in performance can be achieved by caching the results from database queries in memory using memcached , or breaking down a database into smaller chunks called shards which can be spread across a number of distributed server clusters.

It supports backing up from all storage engines. They are based on Group Replication, open source tools.

MariaDB offers a similar offer in terms of products [94]. Some common deployment models for MySQL on the cloud are:. A graphical user interface GUI is a type of interface that allows users to interact with electronic devices or programs through graphical icons and visual indicators such as secondary notation, as opposed to text-based interfaces, typed command labels or text navigation.

GUIs are easier to learn than command-line interfaces CLIs , which require commands to be typed on the keyboard. Third-party proprietary and free graphical administration applications or "front ends" are available that integrate with MySQL and enable users to work with database structure and data visually.

Some well-known front ends are:. A command-line interface is a means of interacting with a computer program where the user issues commands to the program by typing in successive lines of text command lines.

MySQL ships with many command line tools, from which the main interface is the mysql client. MySQL Utilities is a set of utilities designed to perform common maintenance and administrative tasks. Percona Toolkit was originally developed as Maatkit, but as of late , Maatkit is no longer developed. Other drivers exists for languages like Python [] or Node. A variety of MySQL forks exist, including the following. From Wikipedia, the free encyclopedia.
