Abstract
This research is concerned with the development of a new model of data base abstraction that is more generalized than the previous models at the discourse level. The data abstraction in this model consists of two parts: concepts and their relationships. Eight different types of relationships have been proposed. Each relationship comes with a set of conditions and a set of storage integrity rules. They are developed from the interaction among data items and the levels of organizational activities.
