Comparative Prediction Methodology for Decentralized DDBMS.

Abstract

As distributed systems grow in size and complexity there is an ever increasing need to construct operating computer models of these systems prior to prototyping or actual system implementation. Simulation of Fully Distributed Processing Systems can entail a most serious modeling and simulation effort. This project deals with the modeling and simulation of Fully Distributed Processing Systems. Two areas of software development, a package directed as a simulation aid to support modularly designed system or nodal algorithmic structures and the model of a distributed multiple-copy data base concurrency control algorithm modularly designed to interface with the simulation support package are treated. The stand-alone Distributed System Simulator, (DISS) is presented in considerable detail to bring out its generality, flexibility and its applicability to a wide range of distributed systems. The algorithm of the SDD-1 Concurrency Control is presented along with simulation results. (Author)
