A modelling tool for office information systems
Julian Lebensold, T. Radhakrishnan, W. M. Jaworski · 1982
Application of ABL, Alternative Based Language, to modelling office information systems is described. This language is powerful for the description of parallelisms and is amenable to stepwise refinement. After studying the different OIS modelling tools, we propose eight requirements of a good modelling tool and examine how well ABL fulfills these requirements. Some capabilities of the ABL environment and user interface are demonstrated. We present the ABL description of an order processing office.
