Match Levels

Using Standard Populations, an application may be set up to match on any of the defined Match Purposes using one of three different Match Levels:

Typical;

Conservative;

Loose.

The choice of Match Level is passed to the SSA-NAME3 "match" function directly by the user’s application.

It is good practice to test using different Match Levels on real production data and volumes to measure the reliability differences.

Typical

A Typical match level for most applications delivers "reasonable" matches. It should be used in typical online or batch transaction searches. It is the default if no Match Level is specified.

Conservative

A Conservative match level for most applications delivers "close" matches. It is generally used in batch systems where accuracy of match is paramount.

Loose

A Loose match level for most applications delivers matches with a higher degree of variation than Typical. It is generally used in systems where the risk of missing a match is high and manual review is available.
