ZOG Approach to Database Management

摘要

ZOG is a general-purpose human-computer interface system that combines the features of a database system, a word processing system, and an operating system shell. The primary features of ZOG are: an emphasis on menu-selection as the primary interface mode; the use of the selection process for navigation in the database, editing the content and structure of the database, and interaction with programs; an architecture that supporst the implementation and growth of very large, distributed databases; and rapid system response. A distributed MIS, based on the ZOG concept, was developed by Carnegie-Mellon University for the USS CARL VINSON, a nuclear-powered aircraft carrier, in cooperation with the ship's crew. This system is a distributed database system implemented on a network of high-powered personal computers (PERQs). This paper focuses on ZOG as a database management system. Using a set of common database problems as a framework, the ZOG approach to database management is discussed and compared with conventional approaches.
