A case study in the use of data base management

Data base management systems have been presented as the means for improving information accessibility and consolidating data processing. In a non-dedicated computer environment the resource allocation that such systems require must be considered. Based on more than four years experience with data base management systems, this paper analyzes the efficiencies and computer resource usage of a data base management system with random access in comparison with the efficiencies and computer resource usage of a data base management system based on sequential and random access.
