Standing Processes in Service-Oriented Environments

Current realization techniques for service-oriented architectures (SOA) and business process management (BPM) cannot be efficiently applied to any kind of application scenario. For example, an important requirement in the finance sector is the continuous evaluation of stock prices to automatically trigger business processes-e.g. the buying or selling of stocks-with regard to several strategies. In this paper, we address the continuous evaluation of message streams within BPM to establish a common environment for stream-based message processing and traditional business processes. In detail, we propose the notion of standing processes as (i) a process-centric concept for the interpretation of message streams, and (ii) a trigger element for subsequent business processes. The demonstration system focuses on the execution of standing processes and the smooth interaction with the traditional business process environment.
