An Interactive Graphic System for Designing and Accessing Statistical Data Bases
Giuseppe Di Battista, Roberto Tamassia · COMPSTAT · 1986
An integrated graphic computer system is presented that supports the whole life cycle of a statistical data base. The system provides design and documentation tools for creating and mantaining a statistical data base, and a user friendly interface for the interactive retrieval of statistical data. Two types of schemas are adopted: Entity-Relationship schemas for elementary data, and special schemas for aggregated data. For each schema, a diagrammatic representation is provided, so that the user can operate on schemas through the corresponding diagrams.
