Question

Quizplus · Accepted Answer

Maximum cardinality refers to the maximum number of instances of one entity class that can be involved in a relationship instance with another entity class. This is also known as the "many" side of a relationship. For example, if the maximum cardinality of a relationship between the entity classes "customer" and "order" is set to 3, it means that a customer can have up to 3 orders associated with them, but not more than that.
