Interview a database analyst or a systems analyst. How do they extract business rules for ER modeling? Ask for specific sources. Are they all listed in the text? Did they purchase an ER model and customize it or design it on their own? How did they decide on naming entity types? Ask the analyst or administrator to show one or two ER diagrams of the primary databases. Study the diagram carefully and look for multiple relationships in the diagram. How have they been modeled? What is the role of identifiers here?
