Integrating enterprise information models in Carnot

The authors describe a method for integrating separately developed information models. The models may be the schemas of databases, frame systems of knowledge bases, domain models of business environments, or process models of business operations. The method achieves integration at a semantic level by using an existing global ontology to develop semantic mappings among resources and resolve inconsistencies. The method is incorporated in a graphical integration tool. The integrated models provide a coherent picture of an enterprise and enable its resources to be accessed and modified coherently
