Abstract

The notion of attribute is presented as a universal construct for describing conceptual and database models. Unifying tools based on the typed lambda calculus give possibilities to define appropriate notions for expressing an equivalency of schemes in different models. Moreover, the expressiveness of conceptual and data models is defined an compared to the recent approaches. A taxonomy of conceptual and database models based on these notions is proposed. particular models will be compared with respect to their expressiveness. Practical consequences of the theory developed could help in constructing so called co-operative information systems as well as in transforming user requirements between two different kinds of information environment.
