  1. Course 7 Reusability, interoperability S. Motogna - Software Quality

  2. Reusability S. Motogna - Software Quality

  3. Reusability • Definition: Extent to which a program can be used in other applications - related to the packaging and scope of the functions that programs perform. • Impact: • Measured: design + implementation • Realized: transition S. Motogna - Software Quality

  4. S. Motogna - Software Quality

  5. Reuse what? • Architecture • Source code • Data • Design • Documentation • Templates • GUI • Requirements • Test cases language paradigm methodology S. Motogna - Software Quality

  6. Reusability • Paradigms: • OOP • Component based programming • Languages: OOL • C++ • Java • Methodology • CBSD • MDD • STL, templates, • multiple inheritance interfaces, RPC S. Motogna - Software Quality

  7. Reuse: metrics & models [W. Frakes, C. Terry – Software Reuse: Metrics and Models, ACM Computing Surveys 28(2), pp. 415-435, 1996] S. Motogna - Software Quality

  8. Furtherreading: • https://www.researchgate.net/publication/282867676_Reusability_Metrics_of_Software_Components_Survey • http://jeffreypoulin.info/Papers/ICSR94/icsr94.pdf S. Motogna - Software Quality

  9. Interoperability S. Motogna - Software Quality

  10. Interoperability • Definition: Effort required to couple one system with another • Impact: • Measured: design • Realized: • operation • transition S. Motogna - Software Quality

  11. use of standard protocols and interface routines use of standard data representations S. Motogna - Software Quality

  12. Interoperability issues • Interoperability => interaction: • Communicate correct • Exchange data and services • Difficulty: heterogeneity S. Motogna - Software Quality

  13. Interoperability Syntactic Semantic achieved only when components agree on the meaning of the data they exchange automatically interpret the information exchanged meaningfully and accurately • guarantees only that data will pass through a connector properly • Specified data formats, communication protocols • Ex. XML, SQL standards S. Motogna - Software Quality

  14. Component A Component B • Middleware: • CORBA • COM • RMI • Microsoft Message Queue S. Motogna - Software Quality

  15. Interoperability • Data interoperabiliy: • XML • JSON • Web interop: • SOAP • Web services • microservices S. Motogna - Software Quality

  16. Enterprise interoperabilityframeworks • 2003: IDEAS: InteroperabilityDevelopments for Enterprise Applicationand Software. • 2004: EIF:The European Interoperability Framework • 2004: e-GIF: e-GovernmentInteroperability Framework • 2006: FEI:The Framework for Enterprise Interoperability • 2006: C4IF: Connection, Communication, Consolidation, CollaborationInteroperability Framework • 2007: AIF: Athena Interoperability Framework • 2007:Enterprise Architecture Framework for Agile andInteroperable Virtual Enterprises S. Motogna - Software Quality

  17. Interoperability metrics • Carnegie Melon: [Carnegie Melon University – Measuring System Interoperability, version 1.0] • Technical compliance measures • Systems interoperability measures • Operational interoperability measures • Organizational and cultural measures Scoreboard: System – score (pass/margin/fail) Scoreboard: System per system – score Information flow - systems– score S. Motogna - Software Quality

  18. Interoperability metrics • LISI (Levels of Information Systems Interoperability) [MITRE, C4ISR] • Level 0: isolated – no connection (manual gateway) • Level 1: connected – electronic connection; separate data & application (email, FM voice, tactical data links, text files) • Level 2: functional – minimal common functions; separate data & application (annotated images, maps) • Level 3: domain – shared data & separate applications (common operational picture) • Level 4: enterprise – cross-domain information, interactive manipulation, shared data & applications (event-triggered global database update) S. Motogna - Software Quality

  19. LCIM - Levels of Conceptual Interoperability Model  • https://www.researchgate.net/publication/224178883_Architecture_constraints_for_Interoperability_and_composability_in_a_smart_grid/figures?lo=1 S. Motogna - Software Quality

  20. Interoperability metrics • ATL Use Case - Software Quality Control Tools Interoperability (Bugzilla, Mantis, Excel) [https://www.eclipse.org/atl/usecases/SoftwareQualityControlToolsInteroperability/] S. Motogna - Software Quality
