Create the Mapping

Create a mapping that looks for duplicate identities. The mapping reads a data source, adds a sequence identifier to the source records, performs identity analysis, and writes the results to a data target.

The following image shows the mapping in the Developer tool:

The mapping that you create contains the following objects:

Object Name	Description
Read_PersistID_Data	Data source. Contains the employee names and details.
Expression	Expression transformation. Adds sequence identifier values to the source data.
Match	Match transformation. Analyzes the levels of duplication in the source data identities.
Write_tgt_PartialMatchNewandAssociate	Data target. Contains the results of the identity analysis.
