One-source Match stage

Edit online

The One-source Match stage matches records from a single source file.

An example of grouping records might be that you locate all records that apply to the same individual, household, or event. In addition, you might deduplicate a file to group all invoices for a customer or merge a mailing list.

The One-source Match stage accomplishes the following actions.
  • Categorizes all records with weights greater than the match cutoff as a set of duplicates.
  • Identifies a master record by selecting the record within the set that matches to itself with the highest weight. The master record is associated with its set of duplicates.
  • Determines that records that are not part of a set of duplicates are nonmatched records. The nonmatched and master records are generally made available for the next pass.
  • Excludes duplicates in subsequent passes. However, you can choose the Independent match type if you want duplicates to be included in subsequent passes.

The output of the One-source Match stage can include master records, duplicates greater than the match cutoff, clerical duplicates, nonmatched records, and statistics about the results of the matching process.
