MySQL is a multithreaded, multi-user SQL database management system which has more than 11 million installations. It is the world’s second most popular and widely-used open source database. It is interesting how MySQL name was given to this query language. The term My is coined by the name of the daughter of co-founder Michael Widenius’s daughter, and SQL is the short form of Structured Query Language. Using MySQL is free of cost for the developer, but enterprises have to pay a license fee to Oracle.
Formerly MySQL was initially owned by a for-profit firm MySQL AB, then Sun Microsystems bought it, and then Oracle bought Sun Microsystems, so Oracle currently owns MySQL.
MySQL is an Oracle-supported Relational Database Management System (RDBMS) based on structured query language. MySQL supports a wide range of operating systems, most famous of those include Windows, Linux & UNIX. Although it is possible to develop a wide range of applications with MySQL, it is only used for web applications & online publishing. It is a fundamental part of an open-source enterprise known as Lamp.
