The crow's-foot notation can show the maximum cardinality involved in a relationship.

Question

Quizplus · Accepted Answer

The crow's-foot notation does indeed indicate the maximum cardinality of a relationship, along with the minimum cardinality. The crow's feet on the ends of the lines connecting entities in a ER diagram indicate whether the relationship is one-to-one, one-to-many, or many-to-many. The maximum cardinality is thus a fundamental aspect of the notation.
