Examples of one-source matching

Edit online

One-source matching is often used to deduplicate lists and identify groups of related records.

Examples of one-source matching are as follows:
  • Grouping all hospital charges for a patient.
  • Finding all members of a household. All persons at a specific address or building are grouped.
  • Deduplicating a file of customer invoices to identify individual customers.
  • Deduplicating a mailing list that was created by merging multiple files.
  • Removing duplicate records that pertain to the same individual, household, event, product, or part, from a data source before updating or creating a data warehouse.
