Title: DATA PROCESSING SYSTEM AND DATA PROCESSING METHOD
Abstract:
With first-type metadata of unstructured data, second-type metadata including content information indicating an attribute of one or more contents of the unstructured data is associated. For each of one or more pieces of unstructured data, two or more pieces of the first-type metadata referring to the unstructured data include a first first-type metadata, which is original metadata of the unstructured data and a second first-type metadata based on a duplicate of the first first-type metadata with which the second-type metadata appropriate to a search condition is associated. A data processing system displays information relating to a plurality of virtual volumes recommended to be used in parallel. With the plurality of virtual volumes, two or more pieces of second first-type metadata based on one or a plurality of overlap degrees of a plurality of pieces of first-type metadata with which a plurality of second-type metadata appropriate to at least one of a plurality of search conditions are associated.
