Based on the concept of a canonical data model, a global schema is proposed for a generalised data base system capable of supporting interfaces to other systems—notably Relational, Codasyl and Adabas—-through appropriate local schemas and data manipulation languages. The proposed global schema consists of entries in the form of normalised relations describing data and data relationships. The investigation of the Relational, Codasyl and Adabas interfaces demonstrates the capacity of the model to support all of them effectively. However, the model is found to impose on the local models certain constraints which help remove inconsistencies and enhance user facilities. The findings of this study are being implemented in a prototype called PRECI.
