Backend Data Base System for the Eglin Computer Network.

摘要

The Directorate of Computer Sciences at Eglin AFB is in the process of upgrading its computer system to meet increased future requirements. Their upgrade includes a revision of the data base query capabilities to handle a projected larger on-line data base capability. A backend data base computer system was investigated as a possibility for meeting the anticipated increase in data base queries. A systems analysis of the Eglin Computer Network's (ECONET) current data base query workload was accomplished to determine a baseline for future workload projections. A modified Multi-backend Data Base System (MDBS - developed by David Hsiao) design was then incorporated into the ECONET and simulated with numerous structural and parametric variations. The parametric variations were to measure performance changes due to changes in workloads and the types of jobs processed. The structural variations were made to measure performance changes caused by changes in hardware configurations. The simulation results were used to select a final backend configuration that, hopefully, would best meet the requirements of data base processing on the ECONET. A MDBS-like configuration with three backend processors was chosen. (Author)
