Detailed explanation-1: -Multiplicity defines how many objects participate in a relationship and it is the number of instances of one class related to one instance of the other class. For each association and aggregation, there are two multiplicity decisions to make, one for each end of the relationship.
Detailed explanation-2: -In UML, multiplicity describes how many instances of one class can be connected to an instance of another class through a given association. This relation is often expressed as a string showing the lower and upper bounds at the endpoints of a connection.
Detailed explanation-3: -There are four types of multiplicities: one-to-one, one-to-many, many-to-one, and many-to-many. One-to-one: Each entity instance is related to a single instance of another entity.
