Tracing the distribution concern: Bridging the Gap

Abstract

Distribution is often presented as an example of a crosscutting concern that is difficult to modularize. This paper presents an approach for modeling distribution using a combination of AOSD and use cases. One of the aims of the paper is to bridge the gap between the handling of crosscutting concerns during the early and later phases of the lifecycle when developing distributed applications. With our approach the distribution concern is modularized in control objects in Analysis, in design control classes in Design and in distributed components in Implementation and Deployment. Use cases are used to establish a clear traceability among the analysis, design, deployment and implementation stages. In this sense, control objects of the analysis have a direct correspondence with distributed components in the implementation and deployment models.
