DATA MANAGEMENT SYSTEM, DATA MANAGEMENT METHOD, AND DATA MANAGEMENT PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a data management system capable of easily generating a schema for defining a data structure. SOLUTION: This data management system includes processes ST1-ST4 for generating a newly derived schema by using either of schemas as a derivation source and changing a data structure element of the schema, and a process ST5 for associating the derived schema with the derivation-source schema and holding them. In the system, the association is utilized when a data set belonging to the derived schema is provided for prescribed processing. COPYRIGHT: (C)2004,JPO
