Engels, Sauer Uni Paderborn Visual Model-based Software Development: Traditional (? ) Approach problem domain implementation program 2

Engels, Sauer Uni Paderborn Visual Model-based Software Development: Reality problem domain „program“ program 3

Engels, Sauer Uni Paderborn Visual Model-based Software Development: Model-based Approach problem domain analyse and design abstracts from irrelevant details model code abstracts from implementation details program 4

Engels, Sauer Uni Paderborn Visual Model-based Software Development: Model-based Approach problem domain analyse and design defined by model code program coded by modeling language programming language 5

Engels, Sauer Uni Paderborn Visual Model-based Software Development Requirements for a Model and the Modeling Language problem domain analyse and design model code Requirements for a Model § user-friendly, understandable § complete § expressive, adequate § correct, precise, analysable program Requirements for a Modeling Language visual, diagrammatic structure & behavior problem domain-specific syntax & semantics 6

Engels, Sauer Uni Paderborn Visual Model-based Software Development Language Engineering (visual) [modeling] language concrete syntax intuition/ meaning end-user aspect mapping abstract syntax (formal) semantics language definition aspect 7

Engels, Sauer Uni Paderborn Visual Model-based Software Development Language Engineering (visual) [modeling] language Object-oriented Modeling of Multi. Media. Applications OMMMA (UML profile) intuition/ meaning concrete syntax mapping graph transformation abstract syntax meta modeling (formal) semantics dynamic meta modeling end-user aspect language definition aspect 8

Engels, Sauer Uni Paderborn Visual Model-based Software Development OMMMA – Object-oriented Modeling of Multimedia Applications User interface • multi-media • multi-functional • multi-modal • interactive integrated model of user interface and system functionality 9
