Practical Complexity in Adapting Object-OrientedApproach of Systems Analysis and Design

摘要

Recently, there has been a surge of interest in adapting object-oriented (OO) concepts, UML, and Unified Process of systemrndevelopment in the Systems Analysis and Design texts. However, there is a question of how to best fit these concepts withrnthe existing coherent discussion of structured approach. This paper addresses some of the intricacies of OO concepts such asrncomplexity of diagrams and models, weak links between phases, and lack of support for designing system components. Wernwould like to recommend that there should be a separate text for the OO methodology and it should not present various OOrnmodels according to the phases of the traditional structured approach, rather it should focus on the evolution of the modelsrnleading to the design of system components. Furthermore, there should be a standard set of models for the OO methodologyrnas well as a clear definition of steps as an analyst moves from one set of models to the next.
