- It is written in C and C++ and works on various system platforms like Linux, macOS, Microsoft Windows, and others.
- The MySQL server software and client libraries use dual-licensing distribution under GPL version 2 or a proprietary license.
- Support can be obtained from the official manual, free support is available in different IRC channels and forums, and Oracle offers paid support via its MySQL Enterprise products.
- MySQL was created by a Swedish company, MySQL AB, and development began in 1994.
- The first version of MySQL appeared on 23 May 1995, initially created for personal usage from mSQL based on the low-level language ISAM.
- MySQL development milestones include significant releases like version 3.20 in January 1997, version 5.0 in October 2005, and version 5.1 in November 2008.
