Question

Visit two local small businesses, one in the service sector (e.g., dry cleaner, auto repair shop, veterinarian, or book-store) and one that manufactures tangible goods. Interview employees from these organizations to elicit from them the entities, attributes, and relationships that are commonly encountered in these organizations. 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?
