  1. Marrying Software Architecture with Configuration Management Techniques Roshanak Roshandel roshande@usc.edu ARR February 2001 USC - Center for Software Engineering

  2. Background • Software Architecture Elements • Components, connectors, configurations, architectural style, architecture description languages (ADL), subtyping • Configuration Management Elements • Change management at source code level, versioned archive, revisions, locks, branches, version tree, system models, configurations USC - Center for Software Engineering

  3. Word Processor develops Architecture Implementation Design Scenario USC - Center for Software Engineering

  4. Architecture System Model • Based on software architecture concepts • ADL and style independent • Component, connector, and interface types • Component, connector, and interface instances • Versioning types to capture architectural evolution USC - Center for Software Engineering

  6. Mae • Architectural evolution environment • Instance of the generic system model • Mapping onto C2SADEL ADL USC - Center for Software Engineering

  7. Graphical environment for specifying versioned software architecture Environment for supporting architecture based evolution Mae Ménage Dradel Implementation Expansion and loose integration USC - Center for Software Engineering

  8. Example Application USC - Center for Software Engineering

  11. Benefits of Mae • Automated change script generation • Architectural level patches • Subtyping relationship to suggest candidate versions of components for replacement • Multi-version connectors • Reliable component upgrade USC - Center for Software Engineering

  12. Future work • Additional design-time functionality for evolving architectural elements • Tight integration of development-time architectural evolution with the evolution of a deployed system, at run-time • Enhancing the Mae environment USC - Center for Software Engineering
