    Explanation:

    In an entity relationship (ER) model, which is the conceptual illustration of certain entities and the relationships that exist between them, the cardinality of a relationship is the possible (minimum and maximum) number of entity occurrences that can be associated or involved in it.

    Note: An entity is a real world object that is being modeled.

    For example, a school has many staff members. The school and the staff members are the objects while the relationship between the school and the staff members is one-to-many.

    One, many, zero are all values of cardinality.
