Is mysql free?

In recent years, MySQL has been one of the most popular open source databases for enterprise-level applications. However, since MySQL was acquired by Oracle, people can't help but worry about whether MySQL is still as free as it used to be.

MySQL is an open source data management system that was born in 1995. The cost is not high and it has certain scalability, so it is widely used in the Internet field. On the basis of its open source, MySQL also provides support for the commercial version, which can provide more professional services to enterprise customers.

However, Oracle acquired MySQL in 2009, which also caused many people to question and worry about MySQL. Because Oracle has always focused on commercialization and charging, some people have begun to wonder whether Oracle will charge or cancel MySQL's open source model.

In fact, Oracle's management of MySQL has not changed its basic open source model. MySQL is still free, and users can freely use and modify its source code under the GPL v2 license.

Businesses using MySQL mainly require paid professional support and advanced features. These paid services include MySQL technical support, database management, data backup, tuning, security, and other advanced options. However, these additional features do not affect the basic use of MySQL.

In addition, Oracle has also released a product called MySQL Community Server. This version can be downloaded and used completely free of charge. MySQL Community Server provides complete functions, including basic functions such as data replication and backup, online data table operations, transaction control, SQL statement writing and management permissions.

In addition, MySQL also has some popular derivative versions, such as Percona Server and MariaDB. These two versions are developed based on MySQL, but add more advanced features and do not have any commercial version or paid options.

In general, the basic version of MySQL is still free to use, and some advanced options require payment. But even if you don't want to pay the extra cost, MySQL Community Server is still a fully functional and stable version that can meet the needs of most enterprises.

It should be noted that although MySQL is open source, it does not mean that it has a strict data privacy protection mechanism compared with other databases. Therefore, when using MySQL, you must carefully review its security measures and settings, and take appropriate security protection measures to prevent data leaks and data security issues.

In short, MySQL is still a free open source database, and under the management of Oracle, the basic functions of MySQL are still open source. Even if users need paid services, it is a derivative version based on existing functions. Therefore, MySQL is still an option worth considering for users who need to use databases in enterprises.
