Describe the possible relationships between entities, in terms of cardinalities
What will be an ideal response?
There are three types or relationships possible between entities depending upon maximum cardinality. These are: A one-to-one relationship exists when the maximum cardinality of each entity is 1. A one-to-many relationship exists when the maximum cardinality on one entity is 1 and maximum cardinality of the other entity is N. A many-to-many relationship exists when the maximum cardinality of both entities is N.
