Question

Consider the statement: “A course has several other courses as a prerequisite.” Which one of the following can be said of the type of class association relationship that is present?
a. Unary association
b. Binary unidirectional association
c. Binary bidirectional association
d. Ternary association

Answer 1

Answer:

d. Ternary association

Explanation:

An association describes a relationship between two classes of an object that must be remembered by a system.  

For example, in a complaint management system, an incident triggers a complaint. The system must remember which complaints were triggered by which incidents. Associations can also encapsulate the basic business rules of an organization.

This relationship is mostly binary will unless the ternary association comes.
