An Efficient Data Source Replicas Consistency Mechanism in Global Enterprise Firms
Global supply chain management(GSCM)making the interactions between applications much easier,but the service delay and unstable network will block the whole business process.Replicated services are a good choice to resolve this problem.The transparency of information become increasingly important in the GSCM as a result of using caching,middleware and distributed database replication etc.technologies to improve the correctness of replicas in business operations.An efficient real-time replicas updating mechanism was proposed to maintain consistent and correct logistic and market information which was shared by all kinds of application systems in transnational enterprises.However,it is difficult for enterprise copies with local or remote original data source(ODS)object partial dependency relationships to maintain their consistency correctness and availableness.With these models,optimization of the correct copy inputs and switching time of each activity in a recursive routing are calculated to obtain the minimum total cost of the project.Finally,our results can be expanded for enterprise database replicas with correctness maintenance abilities.
