SYSTEM FOR DECIDING SET OCCURRENCE STORING ORDER OF MULTI-HIERARCHICAL DATA BASE

摘要

PURPOSE:To produce a data base corresponding to designation by using a set key to decide well-definedly a pair of an owner record and a member record. CONSTITUTION:This device consists of a data base DB generating file 1, a set information sorting means 2 which sorts the owner and member records stored in each record of the file 1 via a set key that secures correspondence between both records, a sort work file 3 which stores the sorted results, a storing order deciding means 4 which has the input of the file 3 and decides the relationship between the set owner and member records, a multi-hierarchical set information producing means 5 which produces the record having the set relationship between the owner and member records covering many hierarchies when the storing order is not decided yet by the means 4, and a storing order file 6 which stores results.
