Alternative Representation of Aspects

According to current views, object-oriented analysis and design focus mostly on system functionality, resulting in difficulties in maintenance and contradictions of the main principles of object orientation. Aspect-oriented software development proposes early specification of nonfunctional requirements. Many works have integrated an aspect-oriented approach into object-oriented modeling, for example, interdependent concern behavior is modeled using extended UML2 activity models. Without loss of generality, we suggest utilizing a new flow-based approach for describing a conceptual integrated picture, using an extended activity digram as a sample case to illustrate our proposed methodology.
