People are in table `person` and phones in table `phone`. Each person can have zero, one or more phones. Phones can exist without being owned by anyone. So `phone` has a _non-identifying_ 1:n relation to `person`.

~~~
[sql]
CREATE TABLE person (
id INT NOT NULL PRIMARY KEY

 
);

CREATE TABLE phone (
[...]
CONSTRAINT fk_phone_person
FOREIGN KEY (person_id) REFERENCES person (id)
ON DELETE SET NULL

 
    
ON UPDATE RESTRICT
 
);
~~~
