System modeling with mixed object and data models

ABSTRACT

System designs are described from object and data centric perspectives. Component-based modeling approaches are well suited to specify structure and behavior of systems in terms of objects and relationships. Ontology-based modeling approaches describe a system's specification using data types and relationships. The Scalable Entity Structure Modeler is a component-based modeling framework suitable for specifying alternative system designs. This approach is extended with XML Schema to support unified dynamic objects and static data specifications for system design specifications. An example illustrating mixed component and data modeling is described using an extended realization of the SESM environment.
