In this article, let us review row-level and column-level tracking options in merge replication and how these are used in detecting conflicts during merge replication.
Merge Replication: Merge replication is used to replicate data in both ways i.e. from the publisher to the subscriber and from the subscriber to the publisher.
The initial snapshot of objects is taken and applied to subscribers. Incremental data changes and schema changes are tracked using triggers and applied to subscribers when the subscriber synchronizes with the publisher.
