Component-Based System Integration via (Meta)Model Composition

This paper provides three contributions to the study of functional integration of distributed enterprise systems. First, we describe the challenges associated with functionally integrating the software of these systems. Second, we describe how the composition of domain-specific modeling languages (DSMLs) can simplify the functional integration of enterprise distributed systems by enabling the combination of diverse middleware technologies. Third, we demonstrate how composing DSMLs can solve functional integration problems by reverse engineering an existing CORBA component model (CCM) system and exposing it as Web service(s) to Web clients who use these services. This paper shows that functional integration done using (meta)model composition provides significant benefits with respect to automation, reusability, and scalability compared to conventional integration processes and methods
