CONSISTENT OBJECT-BASED SOFTWARE CONSTRUCTION FOR EMBEDDED APPLICATIONS

摘要

In this article a new method for a consistent object-based software construction will be suggested, that allows a straightforward modeling of embedded applications. To this aim new diagram types, the so-called state-based collaboration diagrams, collaboration diagrams in layer models and client-server object diagrams will be introduced. The client-server object diagram is completely UML-conform and for the state-based collaboration diagrams and the collaboration diagrams in layer models only a few UML extensions are necessary. The new state-based collaboration diagrams will prevent discrepancies between objects' interactions and state charts, and the collaboration diagrams in layer models will allow a consistent transition between analysis and design, and furthermore a consistent consideration of the dynamic and static properties of an architecture. In the case of safety-related systems the collaboration diagrams in layer models help to decouple functions of different safety integrity levels according to IEC 61508. And last but not least the client-server object diagrams will support the transition between the activities system analysis and system design as well as the transition between system design and implementation.
