Description
Summary:Database consistency is one of the major issues in replicated database in distributed database systems. The logical design for the replicated nodes and the transaction management mechanism are two aspects that give a serious impact to the performance and the consistency of replicated databases. This paper proposes a new model that combines the Neighbor Replication on Grid (NRG), where the data is replicated to the neighbors of the grid with the Update Ordering approach. The performance comparison shows that the proposed mechanism greatly improves the performance of the replicated database up to two orders of magnitude while preserving the data consistency.
