  1. Grady Booch Software Architecture Masterclass- September 2007Breakout session:Architecture Representation Nick Whidborne (Reporter, IBM) Richard Hopkins (Facilitator, IBM) Behzad Bordbar (Presenter, academia)

  2. Contents • Architecture • Architecture Description Languages • Development and tool support • Brownfield Software Systems

  3. Architecture IEEE 1471- ISO/IEC 42010 Recommended Practice for Architectural Description of Software-Intensive Systems (2000) • Expression of the system and its evolution • Communication among the system stakeholders • Evaluation and comparison of architectures … • Planning, managing, executing system development • Expression of persistent characteristics .. to guide acceptable change • Verification of a system implementation • Recording … the body of knowledge …

  4. Architecture Description Languages Among many are Wright, Rapide, Darwin, SADL, C2,… IBM’s ADS: augments UML for -definition of functional architecture -description of operational architectures … Advantages of UML • family of multiple languages - good tool support • accepted by industry -good extension mechanism … But you may disagree- as it emerged in Code Generation conf., Cambridge 2007 May be Domain Specific Language (DSL) is the future of ADL?

  5. Development and tool support Model Driven Development (MDD) Areas of considerable progress: • Representation of source and destination (meta)models • Exchange/repository of models • Specification of model transformation • testing, verification patterns … are still subject of research • Good tool support environment is available both in academia and industry

  6. Development and tool support Eclipse: • Easy to develop plug-in, lots of plug-ins… • Better/faster tool development. But, existing MDD technology by and large is aimed at the developers. There is a clear shift in the role of IT. Crucial to bridge the gap between business models and architectural models? • How can MDA support the architect? • Also, MDD is about forward engineering, what about Brown-field Development?

  7. Brownfield Software Systems Challenges: • Harvest details to understand the architecture • Raise the level of abstraction • Visualise to discover crucial dependencies • Richard’s recent work on Second life Are our standards suitable for capturing models of legacy systems?

  8. Methodologies Among others: • Rational Unified Process • Global Services Method • Agile Unified Process • Extreme Programming Does the representation sets the methodology or the methodology sets the representation?
