Abstract:
1. A non-transitory computer program product for data management, the computer program product comprising a computer readable storage medium having computer readable program code embodied therewith, said computer readable program code being executable by a processor to: determine an access frequency of current data based on past or current usage; check to see if said current data is associated with previous data access history such that knowledge of said previous data access history needs to be combined with said current data access history to provide an overall current data access frequency; assign said current data based on its overall current data access frequency to a first tier of a plurality of hierarchical ordered tiers, each tier corresponding to at least one class of storage; check to see if a condition overrides said current data association with said first tier and, if so, reassign said current data to a different tier of said plurality of hierarchical ordered tiers; and preserve tier assignment and said overall current data access frequency of said current data so that said current data can be appropriately assigned in the future.
