GUIDE: Graphical User Interface for Database Exploration

摘要: This paper describes a system which uses graphics devices as tools to interface complex databases. The difficulties associated with using query languages for large, databases such some of the statistical (e.g., Census data, energy data) are examined, We will describe containing features subject directories, help messages, zooming facilities relevant part database schema, and partial formulation intermediate results. offers user. schema is displayed network entity relationship types. Queries can be expressed traversal paths on this network. Partial queries (called “local queries”) formulated represented graphically retrieval results any local available at time. Local linked together form larger provide basis building in piecemeal fashion. Parts selectively made visible or invisible representing multiple levels details schema.
