Question
Which of the following statements are false?Select one or more:If the same item can be associated with multiple containers of the same type, then use a regular association.Both Aggregation and Composition are a kind of "part-whole" relationship (association)A specific room will be part of one and only one building. This is an example of Aggregation relationshipA student can appear in multiple classes. This is an example of Composition relationshipComposition is a special form of aggregation. In a composition, the items "belong" to the container, while in a standard association, the items are merely associated with the container.
Solution
The following statements are false:
-
"If the same item can be associated with multiple containers of the same type, then use a regular association." This statement is false because it depends on the context and the nature of the relationship between the item and the container. If the item is part of the container, then it would be more appropriate to use an aggregation or composition relationship.
-
"A student can appear in multiple classes. This is an example of Composition relationship." This statement is false because a composition relationship implies that the part (student) cannot exist without the whole (class). However, a student can exist without being part of a class, and a student can be part of multiple classes. Therefore, this is an example of an association relationship, not a composition relationship.
