Abstract:
The decentralization of organizational units led to database distribution in order to solve high availability and performance issues regarding the highly exhausting consumers nowadays. The distributed database designers rely on data replication to make data as near as possible from the requesting systems. The data replication involves a sensitive operation to keep data integrity among the distributed architecture: data synchronization. While this operation is necessary to almost every distributed system, it needs an in depth study before deciding which entity to duplicate and which site will hold the copy. Moreover, the distributed environment may hold different types of databases adding another level of complexity to the synchronization process. In the near real-time duplication process, the synchronization delay is a crucial criterion that may change depending on querying trends. This work is intended to establish a standard synchronization process between different sites of a distributed database architecture including database heterogeneity, variable synchronization delays, network capability restrictions and fault management ability.
