What is this called?

[whydna]

Class UsersXXX
{
    public function createUser($username, $pass, $email)
    {
         $sql = insert into...
         mysql_query($sql);
    }

    public function getLatestUsers($max = 10)
    {
         $sql = select from ...
         mysql_query($sql);
         return $results;
    }
} 

Not functional obviously. But what is this technique of abstracting a database table called? Models? DAO?

Thanks
