On the gross architecture for the next generation Database Management Systems
G. M. Nijssen · 1978
After analyzing the major problems with current information systems, a description is given of how some of these problems may be solved. An essential tool in narrowing the understanding gap between computer specialists on the one side and managers and end-users on the other, is the conceptual schema. The requirements for the concepts in the conceptual schema are discussed and the major candidates for the conceptual schema are briefly evaluated. A gross architecture for the next generation database management systems is presented; essential in this architecture is the conceptual schema, the coextistence of various user mental models and the coexistent use of various manipulation languages as well as the coexistent use of various physical databases on one or more computers. Hence we have given it the name: COEXISTENCE model.
