Patent ID: 8667026

Claim:
A computer implemented method, comprising: for a regulated data source in a plurality of regulated data sources: evaluating, using a computer-based system for assessing data sources, a first count of records in said regulated data source having an identical value for a first data field as at least one other record in said plurality of regulated data sources; evaluating, using said computer-based system, a second count of records in said regulated data source having no identical values for said first data field in said plurality of regulated data sources; calculating, using said computer-based system, a numerical difference of said first count and said second count; assigning, using said computer-based system and based on said difference, a first regulated data source ranking for said first data field for said regulated data source of said plurality of regulated data sources; assigning, using said computer-based system, a second regulated data source ranking for a second data field for said regulated data source; for a non-regulated data source in a plurality of non-regulated data sources: evaluating, using said computer-based system, a third count of records in said non-regulated data source having identical values for said data field and for at least one record in said regulated data source in said plurality of regulated data sources; and assigning, using said computer-based system and based on said third count, a non-regulated data source ranking for said non-regulated data source of said plurality of non-regulated data sources.
