Abstract: A system replicates and synchronizes data objects between a source system and a target system while managing changes in user access control, even when the target system is offline. Initially, a set of data objects accessible to a user based on their access control specification is sent from the source system to the target system. If a change in access control occurs while the target system is offline, the change is recorded within a sequence number, indicating the order of events. Once the target system comes back online, a data synchronization is performed, ensuring that new data objects made accessible by the access control change are transmitted to the target system.

Abstract: A system replicates data stored in a source database to target databases of systems such as mobile devices. The source database stores data objects, for example, documents, media objects, and so on. The source system ensures that the data objects stored in a target database correspond to a set of data objects that can be accessed by the user associated with the target database as determined by an access control specification of the user. Accordingly, if the access control specification of the user changes, the source system performs data synchronization to modify the set of data objects stored on the target database. If the access control specification is modified to revoke the user's access to a set of data objects, the source system performs data synchronization to send information identifying the set of data objects with a request to remove the data objects from the target database.
