Aspect-oriented design model.

Abstract

Designing crosscutting concerns (aspects) is a challenging task. Since crosscutting concerns were not addressed while developing contemporary software design techniques, so they lack support for accommodating representation of such concerns along with base program. Some design languages like UML have been extended to express aspects and their elements but they do not fully represent aspects. Some lack adequate representation of aspect elements and some lack an efficient and reusable composition technique. In this paper, some of the aspect-oriented design techniques have been critically discussed. A proposed aspect model has been discussed which helps in overcoming the deficiencies in the contemporary aspect-oriented design techniques. This model represents aspects and their elements throughout the software development life cycle
