Learning The Differences Between Ontologies and Conceptual Schemas Through Ontology-Driven Information Systems

In the traditional systems modeling approach, the modeler is required to capture a user’s view of some domain in a formal conceptual schema. The designer’s conceptualization may or may not match with the user’s conceptualization. One of the reasons for these conflicts is the lack of an initial agreement among users and modelers concerning the concepts belonging to the domain. Such an agreement could be facilitated by means of an ontology. If the ontology is previously constructed and formalized so that it can be shared by the modeler and the user in the development process, such conflicts would be less likely to happen. Following up on that, a number of investigators have suggested that those working on information systems should make use of commonly held, formally defined ontologies that would constrain and direct the design, development, and use of information systems – thus avoiding the above mentioned difficulties. Whether ontologies represent a significant advance from the more traditional conceptual schemas has been challenged by some researchers.
