Merge replication allows various sites to work independently (online or offline) and merge data modifications made at multiple sites into a single, uniform result later on. The initial snapshot is applied to Subscribers and SQL Server 2000 tracks changes made to the published data at the Publisher and at the Subscribers. The data is synchronized between Publisher and the Subscribers either at a scheduled time or when demanded. The data to be replicated are updated independently (i.e., without no commit protocol) at multiple servers.

As a result, the same data may have been updated by the Publisher or by more than one Subscriber. Therefore, conflicts may occur when data modifications are merged. Merge replication includes default and custom choices for conflict resolution that can be defined while configuring a merge publication. When a conflict occurs, the Merge Agent invokes a resolver to determine which data will be accepted and propagated to other sites. Merge replication provides options for filtering published data horizontally and vertically, including dynamic filters and join filters. |
