Incremental Integration of Heterogeneous Systems Views

To master systems complexity, their industrial development requires specialized heterogeneous views and techniques and - correspondingly - engineering tools. These views generally cover only parts of the system under development, and critical development defects often occur at the gaps between them. To successfully achieve an integration that bridges these gaps, we must tackle it both from the methodical as well as from the tooling sides. The former requires answers to questions like: What are the views provided by the tools? How are they related and extended to achieve consistency or to form new views? - while the latter requires answers to: How are views extracted from the tools? How are they composed and provided to the user? Our approach, suitable for incremental integration, is demonstrated in the tool integration framework ToolNet.
