摘要： In a data processing system (100), a mechanism identifies data items by substantially unique identifiers (138, 140, 142, 144, 146, 148, 150) which depend on all of the data in the data items and only on the data in the data items. Existence means determine whether a particular data item is present in the system, by examining the identifiers of the plurality of data items.
