Ans: Cardinality defines the number of entities to which other entity can be related via a relationship set. It may be 1:1, 1: N or M: N.
In a relationship set Participation of an entity set can be total or partial. It is total if each entity participates in the relationship. If only a few entities participate in a relationship after that it is partial.
