Which of the following indicates the maximum number of entities that can be involved in a relationship?
-
Minimum cardinality
-
Maximum cardinality
-
ERD
-
Greater Entity Count (GEC)
Maximum cardinality specifies the maximum number of entity occurrences that can be associated with a single occurrence of a related entity. Minimum cardinality defines the lower bound, while ERD is the diagram format itself.
To answer this question, you need to understand cardinality in the context of entity-relationship diagrams (ERD).
Option A) Minimum cardinality - This option is incorrect because minimum cardinality refers to the minimum number of entities that must be involved in a relationship. It does not indicate the maximum number of entities.
Option B) Maximum cardinality - This option is correct because the maximum cardinality of a relationship denotes the maximum number of entities that can participate in that relationship. It indicates the upper limit of the number of entities that can be involved.
Option C) ERD - This option is incorrect because ERD stands for entity-relationship diagram, which is a graphical representation of the entities and their relationships. It is a modeling tool and does not specifically indicate the maximum number of entities in a relationship.
Option D) Greater Entity Count (GEC) - This option is incorrect because Greater Entity Count is not a commonly used term in the context of entity-relationship modeling. It does not specifically indicate the maximum number of entities in a relationship.
The correct answer is B) Maximum cardinality. This option is correct because it indicates the maximum number of entities that can be involved in a relationship.
