Responsibility-driven systematic object identification process for object-oriented software development

Abstract

The most critical work in the development of object-oriented software is how to find out object. This fact is self-explaining in the name of "object-oriented". Though there are many object-oriented methodologies, almost no methodology has meaningful contribution to object identification but focus upon just new notation set for representing object-oriented concepts. Notation itself has little meaning. If OO concepts could be represented, any notation set will do. Practically the very most important is the construction of object model with high quality. The thesis is written for suggesting systematic object identification process which helps the analyst find out quality objects especially in the software having GUI. Software system is also a sort of "system". Therefore systems engineering process, which is recursive decomposition process, could be applied to object identification process. Objects directly correspond to components of system. The systematic object identification process is recursive decomposition with useful heuristics about object identification. The critical milestone is employing the concept of responsibility as a decomposition criteria. Responsibility is a set of inherent data, functions, and relationships. To help analysts recognize responsibility, the thesis suggested several useful heuristics. Macrostereotype and microstereotype, and their generic responsibilities would give analysts insights to grasp the system at a glance. The generic system scenario, which is made up of macrostereotypes, would be practical aids for whereqq to start the system dynamics. The idea on rule modeling would help to decide the subtle rule distribution problem. And the thesis also suggested metrics set for good object identification. Metrics set can be used to evaluate the quality of object and feedback object identification. As an example, the thesis select academic courses registration system of CAIS. By this system, the thesis will first reverse and forward e...
