Entity-Relationship and Object-Oriented Data Modeling-an Experimental Comparison of Design Quality

  title={Entity-Relationship and Object-Oriented Data Modeling-an Experimental Comparison of Design Quality},
  author={Peretz Shoval and Sagit Shiran},
  journal={Data Knowl. Eng.},
We compare EER and OO data models from the point of view of design quality. Quality is measured in terms of (a) correctness of the conceptual schemas being designed, (b) time to complete the design task, and (c) designers' preferences of the models. Result of an experimental comparison of the two models reveal that the EER model surpasses the OO model for designing unary and ternary relationships, it takes less time to design EER schemas, and the EER model is preferred by designers. We conclude… CONTINUE READING
