Property Value

Remarks

In peer-peer synchronization, you must track inserts, updates, and deletes for each table that is synchronized. This can be handled by using coupled or decoupled change tracking. Coupled change tracking means that change tracking metadata for inserts and updates is stored in the base table, with a tombstone table to track deletes. Decoupled change tracking means that metadata for inserts, updates, and deletes is stored in a separate table, typically one table for each base table. With either kind of change tracking, the commands that you specify for the DbSyncAdapter object use change tracking metadata to determine the incremental changes that have been made at each peer.

The examples in this documentation use decoupled change tracking. For information about a sample that uses coupled tracking, see Sample Applications for Peer-to-Peer Synchronization.
