Match Transformation

Match Type Options in Identity Match Analysis

Effective in version 10.0, you can select the following options when you configure the Match transformation to read a persistent store of identity index data:
Remove IDs from the database
The transformation deletes rows from the index tables if the rows share sequence identifiers with rows in the mapping source data. The transformation does not perform match analysis when you select the option.
Update the current IDs in the database
The transformation replaces rows in the index tables with rows from the mapping source data if the rows share sequence identifiers. The transformation does not add rows to the index. The transformation can include the rows that it does not add in the match analysis.
For more information, see the "Match Transformations in Identity Analysis" chapter of the
Informatica 10.0 Developer Transformation Guide
.

Matching Process Options in Identity Match Analysis

Effective in version 10.0, you can enable and disable match analysis when you configure the transformation to update a persistent store of identity index data. Use the
Matching Process
option to enable or disable match analysis.
For more information, see the "Match Transformations in Identity Analysis" chapter of the
Informatica 10.0 Developer Transformation Guide

Status Codes for Identity Analysis with an Persistent Index Store

Effective in version 10.0, the Match transformation can generate the following status codes to describe the results of match analysis on a persistent index data store:
Absent
The index data store does not contain data for the current record.
Invalid
The transformation cannot analyze the current record. For example, the transformation cannot generate index data for the record because the key field on the Match Type tab is not compatible with the record data.
Removed
The transformation removes the index data for the record from the index data store.
Updated
The transformation updates the rows in the persistent data store with index data from the transformation input record. The transformation input data and the persistent index data have common sequence identifiers.
For more information, see the "Match Transformation" chapter of the
Informatica 10.0 Developer Transformation Guide
.

Parameter Usage

Effective in version 10.0, you can use parameters to set the following options on the Match transformation:
  • The match score threshold value.
  • The relative weight that the transformation applies to the scores from each match strategy.
  • The persistence method that the transformation applies to the persistent index data store in identity match analysis.
For more information, see the "Mapping Parameters" chapter of the
Informatica 10.0 Developer Mapping Guide
.

Sequence ID Port

Effective in version 10.0, the Match transformation output ports include a Sequence ID port when you configure the transformation to read a persistent index store. The transformation uses the sequence identifier values to track the index data through the different stages of the match analysis.
