One of my specialties in Data Quality is Data Matching.
Data Matching is about linking – and eventually also splitting before linking – entities in or between databases, where these entities are not already linked with unique keys.
Matching party data – names and addresses – is the most common area where Data Matching is practiced and a lot of tools are available. Matching includes:
- Deduplication
- Match with external reference data and
- Identity Resolution.
