Abstract

Modelling the dynamic aspects of an object-oriented design is important in order to gain concrete insight into the ways objects interact and relate to each other. It may be possible to obtain a similar insight from a static model, but at a more abstract level and in a more indirect way. Dynamic models are usually presented as graph-based diagrams in which the vertices are objects and the edges are messages or relations among objects. In this paper we study such diagrams as the basis for tools in a dynamic modelling environment. We are especially interested in different ways to present time in such tools. One particular approach is to present 'time by time'. This leads to animation of dynamic models. By introducing the idea of 'design by animation' we aim at a radical improvement of the presentation and manipulation of dynamic models in contemporary CASE tools.
