ABSTRACT:
Data is decayed over time by a type of data item by identifying constituent units of each data item; creating a shelf-life criterion for the constituent units by assigning dimensions to each data item and to each constituent unit; for each of the data items of the data item type, establishing relationship factors for each data item to other data items, between constituent units within data items, and between data items; periodically calculating or updating a decomposability index for each constituent unit as a function of the priority dimensions and the data life dimensions by moving the index towards a threshold for constituent units which are reproducible; and subsequently, decaying the data by deleting from storage constituent units which have decomposability indices exceeding a configured threshold, thereby reducing the amount of storage occupied by a remaining plurality of data items.
