Aspect-oriented design model.

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

Representing Aspects in Design

Identification of cross-cutting concerns (Aspects) in the earliest phases of software development has gained in popularity over recent years. Many approaches have been suggested for identifying and representing Aspects in abstraction and design structures. Since these approaches are still relatively immature, shortcomings such as overlooking or not properly locating Aspects have been noted in almost all of these approaches. This research proposes an Aspect- Oriented Software Development Model which helps identifying Aspects at the early stages of software development and guides the way to interpret these Aspects into Design elements and finally provides a support to weave Aspects into Base program
