MySQL is an Open Source Relational Database Management System (RDBMS) based on Structured Query Language (SQL).
MySQL runs on virtually all platforms, including Linux, UNIX, and Windows. MySQL is most often associated with web-based applications and open source enterprise stack called LAMP. LAMP is a Web development platform that uses Linux/Unix as the operating system, Apache as the Web server, MySQL as the relational database management system and PHP as the object-oriented scripting language. [Sometimes Perl or Python is used instead of PHP.]
