Providing a tentative data status on the user interface
The tentative nature of replica data means that a transaction that is committed in a replica can be changed in the master database. Sometimes this has visible implications to the application itself. For instance in an order-entry system, the status of an order can first be Tentatively OK, which means that it has been accepted by the replica, but not yet by the master. In your application design, consider that you might want to show the tentative status also to the user.
