Selective replication-data replication, Database Management System

Selective replication: This is a combination of generating small fragments of relation and replicating them rather than a entire relation. The data should be fragmented on require basis of several sites, as per the frequency of use, or else data is kept at a centralised site. The aim of this strategy is to have just the benefits of the other approach but none of the drawbacks. This is the most commonly used strategy as it gives flexibility.
