| Description |
E-business processes are typically developed by composing
internal processes and external processes offered by service providers.
Whereas e-service integration has received considerable interest recently,
the relationship between the behavior of the composite process and the behavior
of the constituting service processes has not yet been thoroughly investigated.
It is natural to expect that the behaviors of the composite process and
the service processes are related as follows:
- The composite process synchronizes the execution of activities from
different service processes.
- The composite process provides a complete overview of the service
processes in that business transactions can be tracked ("observed")
over their entire life time across all services.
- If an activity can be invoked according to the composite process,
it can be successfully invoked in the respective service process.
- The description of the composite process, focussing on coordination,
abstracts from local details as far as possible.
Based on these requirements, the projects deals with the following problems:
- Introduction of formal correctness criteria for business-process composition
- Introduction of algorithms for composition based on the correctness
criteria
- Workbench for translating existing service processes into a conceptual
service definition language and for monitoring and controlling the execution
of business cases according to the composite business process
