Chapter 24. Replication Made Easy > Resolving Replication Conflicts

Resolving Replication Conflicts

When the Jet Engine tries to synchronize two databases, it might find that the same row has been changed in both databases, so a conflict results that must be handled. The rule is that the database in which the row has changed most often wins. If both rows have changed the same number of times, the winner is chosen randomly. This might sound frightening, but it isn't as bad is it seems because you can let the user know which changes were rejected.

You must know whether two members of the replica set contain conflicting information. Two users out in the field might have entered different information about a sale or a customer, so it's important that the program identify these inconsistencies and have a method for handling them.
