Feature-based rationale management system for supporting software architecture adaptation
(World Scientific Publishing Co. Pte. Ltd., 2012) Tekinerdogan, B.; Sozer, H.; Aksit, M.
Each software architecture design is the result of a broad set of design decisions and their justifications, that is, the design rationale. Capturing the design rationale is important for a variety of reasons such as enhancing communication, reuse and maintenance. Unfortunately, it appears that there is still a lack of appropriate methods and tools for effectively capturing and managing the architecture design rationale. In this paper we present a feature-based rationale management approach and the corresponding tool environment ArchiRationale for supporting software architecture adaptation. The approach takes as input an existing architecture and captures the design rationale for adapting the architecture for a given quality concern. For this we define a feature model that includes the possible set of architectural tactics to realize the quality concern. The presented approach captures the rationale for deciding on feature selections and for selecting the corresponding architecture design alternatives. ArchiRationale customizes and integrates the Eclipse plugin tools XFeature, ArchStudio and XQuery to provide tool support for capturing, storing and accessing the design rationale. We illustrate the approach for adapting a software architecture for fault tolerance. © 2012 World Scientific Publishing Company.

Managing aspect orderings to support multiple quality concerns
(IEEE, 2009-03) Tekinerdoǧan, B.; Er, E.
When multiple aspects are composed undesired behavior may emerge due to the interference of aspects. Different interference management approaches have been proposed including detection and resolution of the conflicting aspects. It appears that the majority of the existing approaches have basically focused on functional correctness, whereby orderings of aspects are evaluated with respect to assumed contractual specification. Although functional correctness is an important quality concern also other quality concerns such as evolvability, reuse and reliability can demand a specific ordering. As such, the resulting possible set of orderings might need to be further reduced. In this paper we discuss the impact of other quality concerns than functional correctness, on the required orderings of aspects. Based on a domain analysis of existing approaches we provide a feature model and complementary to this a metamodel for defining aspect interference management approaches for multiple quality concerns.
