Improvement of Object-Oriented System Analysis and Design with Aspects

Although there are already many researches on aspect-orientation software development from requirements to design and implementation, there is not a practical way for adapting aspects to current Object-Oriented System Analysis and Design (OOSA&D) process. This paper presents a means to model crosscutting concerns based on OOSA&D. The approach is based on use-case driven development. Aspects which present crosscutting concerns are identified from use-case diagram, and then aspect specification table is used to describe the aspects in detail. Particularly the presentation is independent of Aspect-Oriented Programming (AOP) languages and the implementation environment. The approach can help developers get clear system structure and facilitate system maintenance and upgrade. This approach is also illustrated by a case study of a Prison Scoring System (PSS).
