Data replication is gaining increased importance due to the increasing demand for availability, performance and fault tolerance in databases.The main challenge for deploying replicated databases on a large scale is to resolve conflicting update requests.In this paper, we propose a permission based dynamic primary copy algorithm to resolve conflicting requests among various sites of replicated databases.The contribution of this work is the reduction in the number of messages per update request.Further, we propose a novel approach for handling single-site fault tolerance including algorithms for detection, removal, and restoration of a faulty site in the database system.
