Using mysql module in puppet manifest

I downloaded mysql module from Puppet Labs.

Here is an example of using it in graphite module.

class graphite {

    $graphite_packages = ["graphite-web","MySQL-python","python-carbon","python-whisper"]
    package { $graphite_packages: ensure => installed }

    $graphite_services = ["httpd","carbon-cache"]
    service { $graphite_services: ensure => running, enable => true }

    file { "/etc/graphite-web/local_settings.py":
           owner => "root",
           group => "root",
           mode  => 644,
           source => "puppet:///modules/graphite/local_settings.py",
           notify  => Service["httpd"],
    }

    file { "/etc/carbon/storage-schemas.conf":
           owner => "root",
           group => "root",
           mode  => 644,
           source => "puppet:///modules/graphite/storage-schemas.conf",
           notify  => Service["httpd"],
    }

    file { "/root/graph.sql":
           owner => "root",
           group => "root",
           mode  => 644,
           source => "puppet:///modules/graphite/graph.sql",
           notify  => Service["mysqld"],
    }

    include '::mysql::server'

    mysql::db { 'mydb':
      dbname         => 'graphite',
      user           => 'graphite',
      password       => 'graphitepassword',
      host           => 'localhost',
      grant          => ['ALL'],
      sql            => '/root/graph.sql',
      import_timeout => 900,
    }

}
