What refers to the minimum no of times an instance of one entity can be associated with an instance in the related entity?

Explanation

Cardinality refers to the minimum and maximum number of times an instance of one entity can be associated with an instance of another entity in a relationship within an Entity-Relationship (ER) Model. It defines the participation constraints between entities. There are three main types of cardinality:One-to-One (1:1): An instance of one entity can be associated with at most one instance of another entity, and vice versa.One-to-Many (1:N): An instance of one entity can be associated with many instances of another entity, but an instance of the many entities can be associated with at most one instance of the one entity.Many-to-Many (M: N): An instance of one entity can be associated with many instances of another entity, and vice versa.
