Abstract

A semantic data model is introduced with the following capabilities:

(1) Abstraction mechanisms for aggregation, generalization and classification,

(2) Unstratified control of the database content,

(3) Refined control of intentional and extensional information, and

(4) Extensive semantic consistency checking.

The basic features of the model are illustrated through a scenario of interactions between the user and the database system (using the proposed model) for constructing a simple database on technical publications.
