Software prototyping approaches are becomin.1 more sophisticated and systems prototyping tools and techniques are rapidly evolving. This paper presents a survey of graphical and textual software prototyping approaches. We dwell on the respective represt ntations, methods, and benefits.We give examples of !ypical software tools available to carry out system prototyping. A taxonomy of prototyping approaches i s liven.
