A Back-End Data Management Experiment.

Abstract

A test system was developed under contract to demonstrate the feasibility of the back-end processor approach. This system was installed on the PDP 11/70 (back-end processor) and tested for validity and performance. This test effort, sponsored primarily by NAVSUP, was to determine whether the originally perceived benefits could be realized and the disadvantages minimized. The perceived benefits were: reduced disk space; reduced main memory for application programs; reduced CPU time for application programs; increased data security; increased host utilization by linking several hosts to one back-end processor; independence of the DBMS from the host processor; and extend the useful life cycle of the host by freeing system resources. The known disadvantages are: an additional computer to operate and maintain; a communications link to maintain, and a development, implementation, and maintenance software effort on two machines. The system implementation, testing methodology, analysis of results, and conclusions/recommendations are discussed in this report.
