business process modeling, object-role modeling, REA ontology

The paper addresses business process modeling with the focus on value modeling, utilizing UML and ORM (Object-Role Modeling) notation. REA (Resource Event Agent) value model, which represents business process model in value modeling framework, is traditionally presented by UML notation. ORM notation is in many ways more specific notation than UML notation with direct relation to ER diagrams. The core of the paper is to present both perspectives and illustrate their comparison and evaluation on a concrete example.
