One MySQL Database service for transactions, analytics, and machine learning.

What is MySQL?

MySQL is the world’s most popular open source database. According to DB-Engines, MySQL ranks as the second-most-popular database, behind Oracle Database. MySQL powers many of the most accessed applications, including Facebook, Twitter, Netflix, Uber, Airbnb, Shopify, and Booking.com.

Since MySQL is open source, it includes numerous features developed in close cooperation with users over more than 25 years. So it’s very likely that your favorite application or programming language is supported by MySQL Database.

How do you pronounce “MySQL”?

“My ess-cue-el” is the “official” way to pronounce “MySQL,” but pronouncing it “my sequel” is common too.

What is the name of the MySQL dolphin?

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

MySQL is a relational database management system

Databases are the essential data repository for all software applications. For example, whenever someone conducts a web search, logs in to an account, or completes a transaction, a database system is storing the information so it can be accessed in the future.

A relational database stores data in separate tables rather than putting all the data in one big storeroom. The database structure is organized into physical files optimized for speed. The logical data model, with objects such as data tables, views, rows, and columns, offers a flexible programming environment. You set up rules governing the relationships between different data fields, such as one to one, one to many, unique, required, or optional, and “pointers” between different tables. The database enforces these rules so that with a well-designed database your application never sees data that’s inconsistent, duplicated, orphaned, out of date, or missing.

The “SQL” part of “MySQL” stands for “Structured Query Language.” SQL is the most common standardized language used to access databases. Depending on your programming environment, you might enter SQL directly (for example, to generate reports), embed SQL statements into code written in another language, or use a language-specific API that hides the SQL syntax.

MySQL is open source

Open source means it’s possible for anyone to use and modify the software. Anybody can download MySQL software from the internet and use it without paying for it. You can also change its source code to suit your needs. MySQL software uses the GNU General Public License (GPL) to define what you may and may not do with the software in different situations.

If you feel uncomfortable with the GNU GPL or need to embed MySQL code into a commercial application, you can buy a commercially licensed version from Oracle. See the MySQL Licensing Information section for more information.

MySQL: the #1 choice for developers

MySQL consistently ranks as the most popular database for developers, according to surveys from Stack Overflow and JetBrains. Developers love its high performance, reliability, and ease of use.

MySQL supports the following popular development languages and drivers:

PHP Python Java/JDBC Node.js
Perl Ruby Go Rust
C C++ C#/.NET ODBC

MySQL has also become the database of choice for many of the most successful open source applications, including WordPress, Drupal, Joomla, and Magento. MySQL is the “M” in the highly popular open source LAMP (Linux, Apache, MySQL, Perl/Python/PHP) stack to develop web applications.

MySQL works in client/server or embedded systems

MySQL Database is a client/server system that consists of a multithreaded SQL server that supports different back ends, several different client programs and libraries, administrative tools, and a wide range of application-programming interfaces (APIs). We also provide MySQL as an embedded multithreaded library that you can link into your application to get a smaller, faster, easier-to-manage standalone product.

MySQL benefits

MySQL is fast, reliable, scalable, and easy to use. It was originally developed to handle large databases quickly and has been used in highly demanding production environments for many years.
