The Identity Resolution transformation is an active transformation that you can use to search and match data in Informatica Identity Resolution (IIR). The PowerCenter Integration Service uses the search definition that you specify in the Identity Resolution transformation to search and match data residing in the IIR tables. The input and output views in the system determine the input and output ports of the transformation.
Configure match tolerance and search width parameters in the Identity Resolution transformation to set the matching scheme and search level. When you run a session, IIR returns the candidate records to the Identity Resolution transformation.
IIR provides online and batch searching, matching, screening, linking and duplicate discovery for all types of identification data stored in Oracle, DB2/UDB, and Microsoft SQL Server tables. IIR uses the IIR Search Server perform to search and match operations.
