Merge Replication

By , About.com Guide

Definition: Merge replication allows the publisher and subscriber to independently make changes to the database. Both entities can work without an active network connection. When they are reconnected, the merge replication agent checks for changes on both sets of data and modifies each database accordingly. If changes conflict with each other, it uses a predefined conflict resolution algorithm to determine the appropriate data. Merge replication is commonly used by laptop users and others who can not be constantly connected to the publisher.
