Presentation Transcript

  1. eODL and SDL in combination for components Harald Böhme Prof. Joachim Fischer

  2. Overview • Motivation • Mission • Used modeling technologies • Development Architecture • Mappings • Outlook

  3. Motivation • Component development: • Abstract methods • Code-generation • Model Driven Architecture (MDA) • Separation of aspects related and unrelated to a specific platform • Platform Independent Model (PIM) • UML 2.0 • eODL in combination with SDL • Problems with Z.130 mapping • Different component platforms  New eODL-SDL mapping

  4. Mission • Define development architecture following the MDA approach with eODL-SDL as PIM • Select a target component platform • Use Meta-Modeling as far as possible

  5. Used modeling technologies • Model Driven Architecture (MDA) • Meta Object Facility (MOF) • Mapping rules • Try to establish relation between source and target model • Implementation language mapping • “traditional” English Text

  6. eODL computational concepts 2 1 SDL 3 implementation concepts 4 5 7 PSM 6 8 Software product Development Architecture PIM CCM C++ Executable

  7. Meta-Models • eODL • Full Meta-Model, all view points are covered • SDL • Ongoing work, diploma thesis, structural aspects • CCM • Full Meta-Model for computational and implementation aspects • So far none for deployment and target environment • C++ • None

  8. computational concepts implementation concepts eODL 2 1 SDL 3 PIM 4 7 PSM C++

  9. eODL to SDL mapping • CO-Type • SDL-Agent-Type • Interface • SDL-Interface • Boost the concept Interface in SDL • Provided Port • SDL-Gate • Used Port • SDL-Interface-Variable • Interaction elements

  10. Enrichment of mapped SDL • Only structural aspects from eODL • Behavioral aspects have to be added • Provision of all Interaction elements • RPC, transitions for consumed signals • Use of environment functionality via Interface-Variables • Call to and output to • Sub-structuring of Agent-Type possible

  11. SDL to C++/CCM mapping • CCM implementation Qedo (C++) • CCM to IDL 2.6 mapping • Implementation Skeletons for business code • User sections • Integration of generated C++ code • Using the user sections • Data type mapping • Direct invocation of procedures not possible • Signal exchange, for preservation of SDL-semantic

  12. Outlook • Deployment view point mappings • SDL, CCM • Completion of Meta-models • SDL, CCM • Tools

  13. Discussion
