Introduction:

In Entity-Relationship modeling (ERD), cardinality refers to the number of instances of one entity that can be associated with each instance of another entity. Cardinality is used to describe the relationship between entities, and it is usually represented as a symbol or a combination of symbols between the entities in the ERD diagram.
