The entity-relationship model: toward a unified view of data

THE ENTITY-RELATIONSHIP MODEL -TOWARD A UNIFIED VIEW OF DATA BY Peter Pin-Shan Chen Center for Information System Research Alfred P. Sloan School of Management Massachusetts Institute of Technology Cambridge, Mass. 02139 ABSTRACT: A data model, called the entity-relatlonship model~is proposed. This model incorporates some of the important semantic information in the real world. A special dlagramatlc technique is introduced as a tool for data base design. An example of data base design and description using the model and the diagramatic technique is given. Some implications on data integrity, information retrieval, and data manipulatlon are discussed. The entity-relatlonship model can be used as a basis for unification of different views of data: the network model, the relational model, and the entity set model. Semantic ambiguities in these models are analyzed. Possible ways to derive their views of data from the entlty-relationship model are presented.
