Model - Based Traces ? ( preliminary

We introduce model-based traces, which trace behavioral models of a system’s design during its execution, allowing to combine modeldriven engineering with dynamic analysis. Specifically, we take visual inter-object scenario-based and intra-object state-based models (sequence charts and statecharts) used for a system’s design, and follow their activation and progress as they come to life at runtime, during the system’s execution. Thus, a system’s runtime is recorded and viewed through abstractions provided by behavioral models used for its design. We present two example applications related to the automatic generation and visual exploration of model-based traces and suggest a list of related challenges.
