An Aspect Enhanced Method of NFR Modeling in Software Architecture

Existence of crosscutting concerns in software requirements often intensifies complexity of software development process. Modeling and analyzing of these concerns in the software architecture decrease possibility of finding tangled and complex components in the ultimate design. Aspect oriented ADLs have emerged to overcome this problem; however, imposing radical changes to existing architectural modeling methods is not easily acceptable by architects. In this paper, we present a method to enhance conventional software architecture description languages through utilization of aspect features with special focuses on non-functional requirements (NFRs).
