Abstract

A method, system and program product maintains consistency of data across a hierarchy of caches. Under the present invention, each data entry in the hierarchy of caches is assigned its own dependency identifier as well as the dependency identifiers of any data entries on which it depends. Thus, the present invention allows corresponding data entries to be linked for automatic invalidation.
