GROUPING COOPERATION SYSTEM, GROUPING COOPERATION METHOD, AND GROUPING PROCESSING FLOW MANAGEMENT PROGRAM

摘要

A grouping apparatus manages user information, and executes grouping processing for extracting a subset which matches a predetermined condition from a set of users. A flow control apparatus transmits a set of users to one of a plurality of grouping apparatuses, and transmits a condition used in grouping processing to each of the plurality of grouping apparatuses. One of the grouping apparatuses transmits, to another grouping apparatus, a first subset which is extracted by executing grouping processing on the set transmitted from the flow control apparatus. The other grouping apparatus extracts a second subset by executing grouping processing on the first subset transmitted from the one of the grouping apparatuses.
