In IDEF1X, ID-dependent relationships are called identifying connection relationships. These relationships exist between two entities where the primary key of one entity is also a part of the primary key of the other entity. This means that the child entity is dependent on the parent entity for its identification. For example, a customer's order is an ID-dependent relationship, where the order table's primary key includes the customer's primary key.
