Abstract

A data model, called the entity-relationship model, which incorporates the semantic information in the real world is proposed. A special diagramatic technique is introduced for exhibiting entities and relationships. An example of data base design and description using the model and the diagramatic technique is given; The implications on data integrity, information retrieval, and data manipulation are discussed.

The entity-relationship model can be used as a basis for unification of different views of data: the network model, the relational model, and the entity set mode. Semantic ambiguities in these models are analyzed. Derivation of their view of data from the entity-relationship model is given. The structured design of relational and network, data bases using the entity-relationship approach is also discussed.
