// UnitOfWork + DataMapper pattern

// Ideally clear DTO
class Person
{
    public $name;
    public $age;
}

// plus a mapper / or a config (xml / yml / php ) file
class PersonMapper extends DataMap
{

    private $tableName = 'users';
    private $primaryKey = 'name';

    public function Update( object )
    public function Delete( object )
    public function LoadById( int $id )
    public function LoadByParams( array $arr )
}

//Usage:
$Person = $UnitOfWork->LoadById(1);
$Person->age++;
$UnitOfWork->update($Person);
