B) entity cluster
C) entity interface
D) entity discriminator

Question

Quizplus · Accepted Answer

An entity cluster is a grouping of related entities in an ERD, intended to simplify the diagram and enhance readability. By creating clusters of related entities, the ERD can be broken down into smaller, more manageable sections that are easier to understand, analyze, and modify. This can help to reduce complexity, increase clarity, and make the ERD more accessible to a wider audience. Entity constraints and discriminators are elements that are used within an ERD to define the relationships between entities, but they do not necessarily simplify the diagram. An entity interface is a type of design pattern used in software engineering, and is not directly related to simplifying an ERD.
