Abstract: A method in an aggregator server of synchronizing data records responsive to variable update notifications includes: receiving, from a provider system, an update notification corresponding to a master data object at the provider system; retrieving a record containing a local data object corresponding to the master data object; determining whether the update notification contains update definitions identifying changes to the master data object; selecting between a delta synchronization mode, when the determination is affirmative, and an object comparison synchronization mode, when the determination is negative; for the delta synchronization mode, updating the local data object according to the update definitions; for the object comparison synchronization mode, obtaining a copy of the master data object, and updating the local data object based on a comparison between the local data object and the copy of the master data object; and storing the updated local data object in the record at the aggregator.

Abstract: A method of aggregating and updating heterogeneous data objects for a client subsystem includes: storing a set of data object definitions, each defining a mapping between an aggregated data object format and a plurality of supplier data object formats; storing a set of update definitions, each defining a mapping between an aggregated update operation and a plurality of supplier update mechanisms; receiving a data object in a supplier data object formats; selecting, based on the supplier data object format of the received data object, a data object definitions and generating an aggregated data object according to the selected definition; presenting the generated aggregated data object to the client subsystem; receiving an aggregated update operation from the client subsystem for updating the aggregated data object; and selecting, based on the received aggregated update operation, one of the update definitions and initiating a supplier update mechanism according to the selected update definition.
