This study investigated the use of ORM as a conceptual modelling technique by using the UML domain model class diagram as benchmark. The rationale was that if the ORM-class diagram compared favourably with the benchmark, then ORM could be proposed as an alternate conceptual modelling technique. Proponents of ORM suggest that it has significant advantages over other techniques for conceptual modelling.
The benchmark UML class diagram was developed according to the Unified Process through use-cases and collaboration diagrams. The ORM-class diagram was derived using the Conceptual Schema Design Process and ORM-UML Mapping Process. The evaluation of the two class diagrams was conducted by means of a questionnaire, based on a set of principles for conceptual models. The study concluded that ORM could not be proposed as a conceptual modelling technique
up to the UML domain class diagram level without considering additional
techniques for capturing the dynamics of the system. / Computer Science / M.Sc. (Computer Science)
