Method, program and system for automatic discovering inter field relationships in heterogeneous data source mixed environments

摘要

PROBLEM TO BE SOLVED: To provide a method, program and system for efficiently associating, with each other, fields for conducting a data analysis across a plurality of data sources differing in design, and responding to various analyses.SOLUTION: The present invention adds an index to a field of each of a plurality of data stores, determines the level of similarity between the fields, and generates data in a graphical form (enterprise data graph) such that fields determined to have high similarity constitute a node. A technique such as a morphological analysis provided by a search engine may be used for the determination of the similarity. The use of the enterprise data graph makes it possible to respond to various inquiry requests across a plurality of data stores.SELECTED DRAWING: Figure 2
