The term _____ is used to label any condition in which one entity occurrence does not require a corresponding entity occurrence
AfilCa [17]

A "cardinality" is any situation where one entity occurrence does not demand a counterpart entity occurrence in a certain relationship.

<h3>What exactly is an entity's cardinality?</h3>

The term "cardinality" refers to the maximum number of relationships that can exist between instances of one entity and instances of another. The lowest number of times an instance in one entity can be connected to an instance in a related entity is known as ordinality, on the other hand.

When anything is counted, the number that results is referred to as its cardinality. As a result, a set's cardinality is equal to the number of its elements. For instance, the set 1, 2, 3, 4, 5 has a higher cardinality of five than the set 1, 2, 3, which has a cardinality of three.
