Database Explanation

Your mySQL server may contain multiple databases. Each database is made up of tables. Each table contains the data, content, and settings that make up your site. Each table name is prefixed. This prefix allows you to have multiple WordPress installations within the same database if you wish. Each WordPress installation in the same database must have its own unique prefix. WordPress installations in different databases may have the same prefix. The default prefix is wp_.
