object-relational mapping: what's best proceed exercise getters?

what should occur i $user->get_email_address()?

option 1: lift email castle database demand

public duty get_email_address() {
    (!$this->email_address) {
        $this->read_from_database('email_address');
    }
    relapse $this->email_address;
}

option 2: lift email castle (and user attributes) database vigilant creation

public duty __construct(..., $id = 0) {
    ($id) {
        $this->load_all_data_from_db($id);
    }
}

public duty get_email_address() {
    relapse $this->email_address;
}

my simple doubt presumably it's best minimize array database queries, presumably it's best minimize volume information gets distant database.

another luck it's best bucket attributes you'll need many / enclose slightest information during vigilant origination all else demand.
