Analysis of the EPMIS Data Base

Abstract

The Emergency Preparedness Management Information System (EPMIS) has been developed as part of a research project with the Defense Communications Agency to build a decision support system for tracking national communications systems in times of emergency. The current EPMIS data base is implemented on the INGRES relational data base management system in a DEC MicroVax environment. The EPMIS program which interfaces with this data base operates at an extremely slow speed. In addition, documentation defining the structure and relationships within the data base is incomplete making it difficult to analyze and improve on its performance. This thesis generates documentation for the EPMIS data base, including an entity-relationship diagram, in order to understand the logical structure of the data base. The EPMIS program is then analyzed to identify processing bottlenecks that degrade system performance. Modifications to the program are made to eliminate the bottlenecks and improve system performance. (kr)
