Data mediation is an essential component in the Modeling and Simulation field (M&S). Managing multiple data sources and exchanging data among multiple systems requires sophisticated tools and a powerful process management system. Business Process Management (BPM) provides a framework for modeling and managing business activities, both manual and automated, in a consistent manner. Managing automated processes offers an opportunity to integrate external applications into the platform. By integrating automated data transformation tools into the business processes using graphical programming, the authors provide an approach to achieve operational interoperability among diverse applications without the need for any application to be aware of any other.
