AspectBreeze: integrating trustworthiness aspects into graph grammar supported architecture description language
Jingzhou Liu, Yuting Chen, Chen Li, Jianjun Zhao · 2014
Aspect-oriented software development (AOSD) has been developed for supporting a long-standing idea of Separation of Concerns (SoC) and enhancing software non-functional attributes including modularity, reusability, and maintainability. Many architectural description languages (ADLs) also provide software developers with support in specifying aspects in software architectures. However, when applied to describe trustworthy software systems, these ADLs face difficulties in using aspects to specify trustworthy attributes and maintaining consistency between the architectures before and after weaving of aspects. In this paper, we extend Breeze, a graph grammar supported ADL, to AspectBreeze. AspectBreeze allows trustworthiness aspects to be easily defined and seamlessly woven into base architectures. Further, architectures are defined along with graph grammars that allow any change to a base architecture to be reflected in the corresponding architecture in which aspects are woven. This paper also presents a case study of an online auction system to show how AspectBreeze is used and how graph grammars can maintain the consistency between the architectures before and after weaving of trustworthiness aspects.
