Framework of Persistence Layer for Synchronous Data Replication (PSR)

Replication is a well - known solution used to improve data availability. Data replication is one of the key components in data grid architecture, clustering and distributed system as it enhances data access and reliability and minimizes the cost of data transmission. This paper proposed a persistence layer synchronous replication technique (PSR). The persistence layer is a synchronous layer based on Computer threading technique .The whole system is a service oriented application. All the replication will have been done through the service oriented practices and in the new technique adding more replicated database server will be easier than ever
