AN OBJECT-ORIENTED MODELING APPROACH TO SYSTEM SOFTWARE-DESIGN

In this paper, a modelling method entitled MOOD (Modelling approach to Object-Oriented Design) is proposed for the design of object-oriented system software. The method employs entity-refinement, functional modelling, and object modelling techniques to model the world of solution-domain objects. The modelling result based on MOOD forms a set of graphic notations that describe the structure, functions, and client-server relationships among the entities. These graphic notations can be mapped directly into object-oriented programming constructs during the implementation phase. MOOD devotes special attention to the reuse of existing components or newly designed components for future reuse. Unlike other methods, which find objects from textural statements, the entity-refinement approach proposed here can identify all the entities and their operations within the solution domain. MOOD is compared with existing methods to show its feasibility and uniqueness.
