The use of a ternary relationship versus a pair, or triple, of binary relationships. The use of a strong or weak entity set. The use of specialization/generalization \u2013 contributes to modularity in the design. The use of aggregation \u2013 can treat the aggregate entity set as a single unit without concern for the details of its internal structure.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
