Integrating Problem Frames with Aspects

Several requirements engineering approaches already provide means for the detection, specification and composition of crosscutting requirements during the preliminary stages of software development. Without the aspect-oriented techniques, the aspectual requirements would still be scattered by the various system components, impeding its implementation in a more modularized way, with a more understandable and easier to modify structure. However, not much has been done to integrate the concepts of aspects in Problem Frames (PF). This paper proposes an approach that integrates PF and aspect-oriented requirements. The result is the construction of more modularized PF models where expressive composition mechanisms are available. The approach was applied to a case study.
