MySQL is a free and open-source relational database management system (RDBMS) that uses Structured Query Language (SQL). It was first released in 1995 and has since become one of the most popular database systems in use today.
MySQL is developed by Oracle Corporation and is part of the LAMP software stack, which stands for Linux, Apache, MySQL, and PHP. MySQL can be used on various operating systems such as Windows, Linux, and macOS.
The source code for MySQL is available under the GNU General Public License (GPL), which means it can be freely used, modified, and distributed by anyone. The source code is hosted on GitHub and is actively maintained by the MySQL development team.
Developers who want to use MySQL can download the source code, compile it, and install it on their system. Alternatively, binary distributions are available for various platforms, making it easy to set up and use MySQL without compiling from source.
MySQL supports many features such as transactions, foreign keys, and indexing, making it suitable for a wide range of applications from small personal projects to large enterprise systems. It also has a variety of client interfaces such as command-line tools, graphical user interfaces, and programming APIs for languages such as Python, Java, and C++.
