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 is most often done with Master Data, but matching is also practiced with Transaction Data and by matching Transaction Data to Master Data. Here I like this definition:
- Transaction data accurately identifies who, what, where and when and…
- Master data accurately describes who, what and where
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.

Doing business directory matching has been a focus area of mine including making a solution for match with the D&B worldbase.
The sub disciplines of data matching are further described in posts about:
Product directory matching and deduplication is also widespread. An example is described in the post Matching Light Bulbs.
Besides these areas a lot of industry specific Data Matching is going on.
A 20 minutes free webinar on eLearningCurve explains it all here. Also, I was a guest on OCDQ Radio explaining the art of data matching.
Data Matching may be deployed in some different ways, where I have been involved in the ones described in the post Deploying Data Matching.
