Abstract: An enterprise system which facilitates synchronization of offline data. Offline data created during an offline session or sessions (collectively an offline session) prior to synchronization is assigned a temporary key. Changes of offline data created during an offline session is assigned the temporary key of the data to which the change is associated. The temporary key is mapped to a new created backend key and stored in a mapping table. Using the mapping table, temporary keys associated with the changes are swapped with backend keys which the temporary keys are mapped. This maintains data persistency of newly created and change data during an offline session.
