Question

MC3. If a resource class represents individually identified resources, the expected multiplicity pattern for its association with an economic event class is

A) Resource 2..1 - 1..2 Economic Event
B) Resource 0..1 - 1..* Economic Event
C) Resource 1..* - 0..1 Economic Event
D) Resource 1..1 - 1..0 Economic Event
E) Resource 1..1 - 0..* Economic Event

Answer 1

The expected multiplicity pattern for an association between a resource class representing individually identified resources and an economic event class is 0..1 - 1..* (Option B). This means a resource is associated with zero or one economic event, and an economic event with one or more resources.

Step-by-step explanation:

The question asks about the multiplicity pattern for an association between a resource class that represents individually identified resources and an economic event class within the context of an entity-relationship model, typically used in business process modeling. The correct answer to this question is B) Resource 0..1 - 1..* Economic Event. This means that for any individual resource, there may be zero or one association with an economic event, but an economic event can be associated with one or more resources. This scenario is common in situations where resources are acquired, consumed, or affected by multiple economic events over time, but at any given point in time, an economic event usually relates to a single specific resource.
