Vista – a Visual Software Technique Approach

This paper describes Vista, a visual multiparadigm language integrated within a comfortable develop-ment environment. Vista supports fundamental software engineering principles during programming such as adequate notation, modularization, and weak coupling. Vista augments the object-oriented pro-gramming paradigm by signal-flow and data-flow based programming. It provides capabilities for the construction of event-driven and data-transformation systems. In constructing an application with Vista, visual as well as textual means can be used. Characteristic features of Vista are especially aimed at the combination of high-level and easy-to-use building blocks that are hierarchically organized. We intro-duce the notion of processors and networks and discuss how a remarkable degree of compositionality and reuse can be achieved by their employment
