Pattern-driven reuse in architecture-centric evolution for service software

摘要

Service-based architectures implement business processes as technical software services to develop enterprise\udsoftware. As a consequence of frequent business and technical change cycles, the architect requires a reusecentered approach to systematically accommodate recurring changes in existing software. Our ‘Pat-Evol’\udproject aims at supporting pattern-driven reuse in architecture-centric evolution for service software. We\udpropose architecture change mining as a complementary phase to a systematic architecture change execution.\udTherefore, we investigate the ‘history’ of sequential changes - exploiting change logs - to discover patterns of\udchange that occur during evolution. To foster reuse, a pattern catalogue maintains an updated collection with\udonce-off specification for identified pattern instances. This allows us to exploit change pattern as a generic,\udfirst class abstractions (that can be operationalised and parameterised) to support reuse in architecture-centric\udsoftware evolution. The notion of ‘build-once, use-often’ empowers the role of an architect to model and\udexecute generic and potentially reusable solution to recurring architecture evolution problems.
