Abstract:
This paper presents a semantic association model called SAM*, which contains six general constructs for modeling the complex relationships (or associations) among data objects. These constructs can be used in an embedded or recursive fashion to allow very complex objects to be explicitly defined in a schema which contains the metadata of an integrated database. In this work, the same semantic model is also used to model the contents of the schema so that the metadata, as well as the application data of an integrated database, can be uniformly defined, stored, displayed, modified, and manipulated by the users. This paper also describes an interactive data dictionary system implemented for the definition and manipulation of metadata and application data modeled by the semantic model.
