Managing Population Rule Sets

A Population rule-set is a file used by the SSA-NAME3 callable routine to modify its behavior for different countries, languages or data populations.

Population rule-sets may be one of three types:

Standard Populations are provided with the product.

A Custom Population may be built by an Informatica Corporation consultant for a customer with unusual or special needs.

A Local Population is the result of local rules modifications done via the Population Override Manager or Edit RuleWizard.

It is possible for a system to have all three types of Population rule-sets. If so, there is an order of precedence in loading by SSA-NAME3. If a Local Population (file extension of

.YLP

) is present in the folder identified by the "System" Control, it is loaded; else if a Custom Population is present (file extension of

.YCP

), it is loaded; else the Standard Population is loaded (file extension of

.YSP

The task of developing name search and matching systems is a balancing act between:

"Performance" and "Quality";

"Under-matching" versus "Over-matching";

"Missing the Right data" versus "Finding Wrong data".
