Abstract

Replication is the technique to provide the opportunity of deadline fulfillment of real-time transaction in distributed real-time database system (DRTDBS). Just-in-time real-time replication (JITRTR), on-demand real-time replication (ORDER), on-demand real-time replication with replica sharing (ORDER-RS), periodic transactions using partial replication (PTUDPR), periodicity prediction algorithm, and so on are the replication protocols designed for DRTDBS. None of the algorithms follow one-copy serializability (1SR) correctness criteria for real-time and non-real-time data items. Our main objective is to fulfill strict consistency together with transaction deadline fulfillment. In this paper, the proposed model works on multi-master together with slave sites and uses middleware for following 1SR correctness criteria. In the proposed model, master sites are responsible for executing update and write transactions and slave sides are responsible for executing only read transaction. The proposed model performs better in terms of deadline fulfillment and strict consistency with respect to other replication protocol.
