MySQL: the Comic Sans of databases. Except Comic Sans has uses.

-- David Gerard

MySQL is a popular open-source database system using the SQL query language. Its files are traditionally stored with the field definitions in .frm files, the data in .myd files, and indexes in .myi files. The newer InnoDB storage engine replaces the .myd and .myi files with a shared "ibdata1" file, and in most cases an .ibd file for each database.
