Aspect-oriented software development has focused on the software life cycle's implementation phase: developers identify and capture aspects mainly in code. But aspects are evident earlier in the life cycle, such as during requirements engineering and architecture design. Early aspects are concerns that crosscut an artifact's dominant decomposition or base… (More)

Software architecture analysis methods aim to predict the quality of a system before it has been developed. In general, the quality of the architecture is validated by analyzing the impact of predefined scenarios on architectural components. Hereby, it is implicitly assumed that an appropriate refactoring of the architecture design can help in coping with… (More)
• On imperfection in information as an "early" crosscutting concern and its mapping to aspect-oriented design…………………………………………………………………..91 Abstract This paper reports on the third Early Aspects: Aspect-Oriented Requirements Engineering and Architecture Design Workshop, which has been held in Lancaster, UK, on March 21, 2004. The workshop included a… (More)

There is now an increasing agreement that aspects are not only an issue at the programming level, but also tend to arise at the requirements analysis and software architecture design. Unfortunately conventional software modeling approaches lack abstractions to support the modular representation of crosscutting concerns in such development stages. Hence,… (More)
Software engineers may experience problems in modeling certain aspects while applying object-oriented techniques [4, 10, 11]. Composition-Filters are capable of expressing various different kinds of aspects in a uniform manner. These aspects are, for example, inheritance and delegation  and atomic delegation , multiple views, dynamic inheritance and… (More)
This paper discusses separation and composition of concerns as a means for improving adaptability of object-oriented programs. Separation of concerns results in a weak coupling of the concerns and as such satisfies the need for increased flexibility and reusability. We will illustrate the separation of concerns mechanism for the conventional object model… (More)
