It helps visualize how data is related and supports database design by defining the structure of the database. b) Data Flow Diagram (DFD) shows data flow and process interactions but not entity relationships. c) UML provides a range of diagrams, including class diagrams and use case diagrams, but ERD specifically represents database relationships. d) Class Diagram is used in object-oriented design to show classes and their relationships, not database entities. e) State Diagram represents states of an object in a system, not entity relationships.
