Aspect-oriented Requirement and Reuse Aspect

Aspect-oriented programming may improve the design level of software, the reusability of components and the implementation of separation of concerns. Component-based software development approach is one of the most promising solutions for the emerging high development cost, low productivity, unmanageable software quality and high risk. This approach, however, encounters the separation of concerns that is easy to lead to the code-tangling and code-scattering. This paper aims to solve this problem on requirement level through the aspect-oriented requirement. At the same time, we also give concerns to the reuse of aspect.
