Guiding Architectural Restructuring through Architectural Styles

摘要

Software architectures constitute one of the main artefacts of software-intensive system development. They outline the essential components and interconnections of a software system at a high level of abstraction, ignoring unnecessary details. How to address the evolution of software architectures, however, is still an important topic of current research. In this article, we use UML 2 as architectural description language notation and formalise it with graph transformation, with a proof-of-concept implemented in the AGG tool. We use this formalisation to express and reason about architectural evolution patterns that introduce architectural styles.
