Quizplus · Accepted Answer

A cluster is a group of related entities in an ERD that can be grouped together to simplify the overall diagram and improve its readability. By clustering related entities together, the overall structure of the ERD is easier to understand and navigate. However, a constraint is a rule or restriction that determines the relationship between entities, an interface is a point of interaction between different components of a system, and a discriminator is a key attribute used to distinguish different instances of an entity.
