Answer to Question 1

For relationships between strong entities, 1:1 and 1:N relationships are called nonidentifying connection relationships and N:M relationships are called nonspecific relationships. ID-dependent 1:N relationships are called identifying connection relationships, but there is no IDEF1X equivalent term for a weak but non-ID-dependent relationship.

Answer to Question 2

TRUE
