Chapter 3, “Data Modeling Using the Entity-Relationship Model" Teorey: Database Modeling and Design, Third Edition, 1999. • Barker: evaluate the significance of the ER-model for DB design. • enumerate the basic constructs of the ER-model. • develop ER-diagrams (schemas in the ER-model) for a given (small)
Entity-Relationship model is used in the conceptual design of a database ( conceptual level, conceptual schema). • Design is independent of all physical considerations. (DBMS, OS, . . . ). Questions that are addressed during conceptual design: – What are the entities and relationships of interest (mini- world)?.
