Visit an organization that provides primarily a service, such as a dry cleaner, and a company that manufactures a more tangible product. Interview employees from these organizations about the entities, attributes, relationships, and relevant business rules that are commonly encountered by their company. Use this information to construct E-R diagrams. What differences and similarities are there between the diagrams for the service- and the product-oriented companies? Does the E-R diagramming technique handle both situations equally well? Why or why not? What differences, if any, might there be in the use of this technique for a public agency?
