Abstract
The data model to generate the conceptual schema should make it easier for users to understand and to express the information in the data base, but this consideration is most often ignored by the conventional data models currently in use today. Understandability and expressiveness of a data base are achieved if the data model meets each of the following criteria: (1) it is structured to reflect information content only, not considerations of physical storage or access strategy; (2) it is able to reflect information content as closely as possible to natural or real world relationships; (3) it maintains clarity and consistency in the set of constructs it uses; (4) it can reflect as wide a set of data relationships as is possible.
This thesis presents a conceptual data model that was developed with these criteria in mind. A design methodology that demonstrates the use of the model in generating a schema is also presented.
