It is a fact of life, or at least of human social organization, that not all information is intended to be made available to all individuals. Thus with MySQL, a database is generally set up in such a way that not everyone can see all of the data (let alone change or delete it). In order to protect data from prying eyes (or unauthorized tampering), MySQL provides a dual access system. The first level determines whether the user has the right to communicate with MySQL at all. The second level determines what actions (such as SELECT, INSERT, DROP) are permitted for which databases, tables, or columns.
