Although closely related, functional and structural aspects of information systems are modeled usually independently of each other. In this paper we propose to combine functional and structural modeling into an integrated design methodology. We choose for this purpose two popular and widely used models, the Data-Flow oriented functional model and the Extended Entity-Relationship (EER) data model. Since functional modeling generally precedes structural modeling the design of information systems, we examine how functional specifications can be represented using EER construct. Our methodology is based on using EER existence dependencies for representing the functional constraints implied by the process interactions. 13 refs., 9 figs.
