Abstract: A method and/or system for identity relationship determination among enterprise data entities to extend master data management is disclosed. The method involves extracting the data from the one or more data sources, thereafter grouping the extracted data into one or more groups based on one or more predefined criteria, then computing a plurality of relationship scores by using one or more soft matching techniques, thereafter creating one or more clusters based on the computed relationship scores, then again calculating a plurality of relationship scores among the clusters, and finally, determining the identity relationships by comparing the plurality of relationship scores generated among clusters with a predefined score.
