I do not understand how they are reflected in the database. The Door class has a $ state (DoorState interface) attribute, this field as it is stored in the database? The State classes are new tables in the database that relate to the state attribute of the Door class? I hope you understand

In your code, only two classes will be reflected in the database (those which extend Phalcon\Mvc\Model):

Door and Dooropen.

The properties of these classes will be mapped to DB columns, which you can fine-tune with:

class Door extends \Phalcon\Mvc\Model {
    public function columnMap() {
        return [
            '<db_column_name>' => '<model_property_name>'
        ];
    }
}

In case I want to add a new state, for example DoorClosed, it should be reflected in the database. I am right? How should I change the relationship in colummap?

    class Door extends \Phalcon\Mvc\Model {
        public function columnMap() {
            return [
                '<db_column_name>' => '<model_property_name>',
                '<db_column_name2>' => '<model_property_name2>'
            ];
        }
    }
