An entity-relationship approach to model management

Abstract

An important purpose of the research being done on decision support systems is to develop a theory of information management that is an independent as possible of the way in which the information is stored and processed. This has important consequences for any proposed theory of model management, for it suggests that a theory of model management should not only help a manager or analyst to organize and access model banks, but it should do so in a way that allows models and stored data to be viewed as complementary sources of information. We present herein an extension of the entity-relationship framework for database organization and processing to include the organization and processing of model banks.
