What Is MySQL

MySQL is undoubtedly the most popular open source Database Management System in all the world. MySQL also ranks as the second most popular database, according to DB-Engines right behind behind Oracle Database.
MySQL enables users to store, manage, and retrieve structured data efficiently. It is widely used for various applications, from small personal websites to large scale Enterprise sites and even corporate level hosting solutions.

Where Did The Name And Logo Originate From

MySQL is a combination of "My" which is co-founder's Michael Widenius's daughter name - My. And "SQL". Which is the acronym for Structured Query Language.

The MySQL logo is a dolphin named Sakila. The name came from users during a contest of “Name the Dolphin”. The winning name was submitted by Ambrose Twebaze, from Eswatini (formerly Swaziland), Africa. Who is also an open source software developer

How Does MySQL Work

MySQL works by allowing its users to create tables and databases. They can store data in these databases then retrieve information from when needed. MySQL stores the data in tables made up of rows and columns. Users can control, define, manipulate, and then query the data using Structured Query Language (SQL). MySQL is written in programming language of C and C++. Its SQL parser is written in yacc, but it uses a home-brewed lexical analyzer.

Who Uses MySQL

MySQL is used by the majority of online applications. Even by the largest websites including Facebook, Twitter, Netflix, Uber, Airbnb, Shopify, GitHub, YouTube, Booking.com, etc.

It is reported that more than 21,000 companies use MySQL in United States alone

Content Management Systems or CMS's like WordPress, Drupal, Joomla, Contao, Sitejet, Concrete5, Bolt, AbanteCart, Mambo, PrestaShop, phpMyFAQ, WikkaWiki, also use MySQL databases

Different MySQL Editions

There are five types MySQL editions to have the flexibility of choosing from to meet specific business and technical requirements

• MySQL Enterprise Edition ─ This edition includes the most comprehensive set of management tools, advanced features, and technical support
• MySQL Standard Edition ─ This edition enables you to deliver high-performance and scalable Online Transaction Processing (OLTP) applications
• MySQL Classic Edition ─ This edition is the ideal embedded database for OEMs, ISVs, and VARs developing read intensive applications using the MyISAM storage engine
• MySQL Cluster CGE ─ This is a real time and scalable ACID-compliant database. ACID - (Atomicity Consistency Isolation Durability), combining 5 x 9s availability and open source technology. With a distributed, multi master architecture with a no single point of failure
• MySQL Embedded (OEM/ISV) ─ MySQL Embedded is the full featured, zero administration database for more than 3000 ISVs, OEMs, and VARs that rely on

What Systems Does MySQL Operates On

MySQL works on a large variety of operating system. This includes AIX, BSDi, FreeBSD, HP-UX, ArcaOS, eComStation, IBM i, IRIX, Linux, macOS, Microsoft Windows, NetBSD, Novell NetWare, OpenBSD, OpenSolaris, QNX, Oracle Solaris, Symbian, SCO OpenServer, Sonos and Tru64.
A port of MySQL to OpenVMS also exists.
You can even install MySQL on your local desktop computer.

MySQL Is Open Source

The MySQL software uses the General Public License (GPL) to define what you may and may not do with the software under 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. See the MySQL Licensing Overview for more information.

What Is A Data Base?

Databases are a structured collection of data. From a simple image gallery to a complete shopping website like Amazon or even a intricate corporate network. These databases allows you to access, add, delete, and process data that is stored. You will need a database management system such as a Web Server running MySQL to access the data. Since our modern computers are very good at handling large amounts of data, database management systems now more than ever play a central role in information storage, as standalone utilities, or as a part of other applications.

What is SQL

SQL was initially created in the 1970s. It is regularly used by database administrators and by developers writing data integration scripts and data analysts looking to set up and run analytical queries. You can use SQL to store, remove, update, retrieve, and search information from the database. You can use it to optimize your database performance.

SQL stands for Structured Query Language

SQL is a programming language that is mainly used in managing databases.

SQL is open-source free to use software. You also have the option to purchase a commercial license from Oracle, which provides access to premium support services.
