Applying object-oriented analysis on a case study

Abstract This paper aims at showing that some object-oriented fundamental principles provide new suitable mechanisms for the analysis and the specification of complex systems. Three principles are presented and discussed in this paper through a case study. The locality principle allows to concentrate on one object, stressing its structure and behaviour through the notion of life cycle, the refinement principle allows to refine objects by means of inheritance links, the globality principle allows to enlighten on different kinds of dependencies amongst objects. The case study is developed with the model of the Modway method. The Modway method is an object-oriented method which makes use of object concepts since the very beginning of the development process.
