Abstract Mo delling the dynamic asp ects of an ob jectoriented design
is imp ortant to gain concrete insight into the ways ob jects interact and
relate to each other A similar insight may b e obtained from a static
mo del but at a more abstract level and in a more indirect way Dynamic
mo dels are usually presented via diagrams which basically are graphs
where the vertices are ob jects and the edges are messages or relations
among ob jects In this pap er we study such diagrams as the basis for
to ols in a dynamic mo delling environment We are esp ecially interested
in dierent ways to present time in such to ols One particular approach
is to present time by time hereby leading to animation of dynamic
mo dels By intro ducing designbyanimation to ols we aim at a radical
improvement of our presentation and manipulation of ob jects in dynamic
mo dels
Intro duction
Diagrammatic graphbased presentations play an imp ortant role as the do cu
mentation of an ob jectoriented mo del This is b ecause of the do cumentation
traditions in early phases of a software engineering pro cess and due to fact that
graphbased mo dels provide attractive and natural overviews of a set of entities
together with their mutual relations
Ob jectoriented mo dels come in two dierent avors Static mo dels and dy
