This paper presents an improved formalism for modeling users' external views. The formalism uses a semantic network where the nodes are data abstractions called concepts, and the edges are modeling functions between concepts. Four different modeling functions are used in the model. Each of these modeling functions comes with a set of integrity rules needed for updating the data. © 1982, Sage Publications.
