  2. Software Development: Traditional (?) Approach problem domain implementation program

  3. „program“ Software Development: Reality problem domain program

  4. abstracts from irrelevant details model abstracts from implementation details analyse and design code Software Development: Model-based Approach problem domain program

  5. problem domain defined by analyse and design modeling language model coded by programming language code program Software Development: Model-based Approach

  6. problem domain model analyse and design code program Requirements for a Modeling Language visual, diagrammatic structure & behavior syntax & semantics problem domain-specific Requirements for a Model and the Modeling Language Requirements for a Model • user-friendly, understandable • complete • expressive, adequate • correct, precise, analysable

  7. end-user aspect intuition/ meaning concrete syntax mapping (formal) semantics language definition aspect abstract syntax Language Engineering (visual) [modeling] language

  8. end-user aspect intuition/ meaning concrete syntax mapping (formal) semantics language definition aspect abstract syntax Language Engineering (visual) [modeling] language Object-oriented Modeling of MultiMediaApplications OMMMA (UML profile) graph transformation meta modeling dynamic meta modeling

  9. OMMMA – Object-oriented Modeling of Multimedia Applications • User interface • multi-media • multi-functional • multi-modal • interactive integrated model of user interface and system functionality
