Increased parallelism-data replication, Database Management System

Assignment Help:

Increased parallelism: Since the replicated date has several copies a query can be distributed or can be answered from the smallest loaded site. Also, with more replicas you have greater chances that the required data is found on the site where the transaction is implementing. Hence, data replication can minimise movement of data among sites.
