Replication is one of the key technologies in promoting the performance of mobile database systems. In this paper, a novel mobile database replication scheme, Transaction-Level Result-Set Propagation (TLRSP) model is put forward. The conflict detection and resolution strategy based on TLRSP is discussed in detail and the implementation algorithm is proposed. In TLRSP model mobile users are allowed to access local replicas of the database and submit local transactions when system is disconnected. The locally committed transactions are sent to the fixed database server for conflict reconciliation and result-set incorporation when system is reconnected TLRSP model uses the incremental refresh method to synchronize database replicas and maintains the consistency of the replicated mobile database system.
