Abstract

We have recently developed an object-oriented refinement calculus called rCOS to formalize the basic object-orient design principles, patterns and refactoring as refinement laws. The aim is of rCOS is to provide a formal support to the use-cased driven, incremental and iterative Rational Unified Process (RUP). In this paper, we apply rCOS to a step-wised development of a Point of Sale Terminal (POST) system, from a requirement model to a design model, and finally, to the implementation in Visual C#.
