Abstract

4Thought, a prototype design tool, is based on the notion that design artifacts are complex, formal, mathematical objects that require complementary textual and graphical views to be adequately comprehended. This paper describes the combined use of Entity- Relationship modelling and GraphLog to bridge the textual and graphical views. These techniques are illustrated by an example that is formally specified in Z Notation.
