Summary:Replication is the key factor in improving availability, fault-tolerance and accessibility of data in all types of distributed systems. Replicated data is stored at multiple sites so that it can be used even when some copies are not available due to site failures and databases are kept synchronized to maintain consistency. The scope of distributing these replicas is local data processing. This paper describes the importance of synchronous partial replication, implementation and query optimization steps using Oracle technology for an E-learning portal of a university with geographically distributed locations.
