Explanation of Solution
Entity cluster:
- An entity cluster is used to represent many entities and relationships in the ER (Entity Relationship) diagram. It is a virtual entity type.
- Combining many interrelated entities into a one abstract entity object is called as an entity cluster.
- It is consider as “abstract” or “virtual” which means it is not actually an entity in the final ER diagram, but in...
