Identifies the population file that the transformation uses. The population file contains the key-building algorithms that generate the index keys.

Determines the number of keys that the identity algorithms generate. The default setting is

Standard

. The

Limited

setting results in a lower number of keys, higher accuracy, and longer processing time. The

Extended

setting results in a higher number of keys, lower accuracy, and shorter processing time.

Describes the type of information that the key field contains. Identity analysis can generate keys for person names, organizations, and addresses. Select the key type that best describes the column that you specify on

Key Field

property.

Indicates the balance of search depth and search speed that the transformation applies to the match analysis. The search depth corelates inversely to the number of matches returned. For example, the

Exhaustive

option returns fewer matches.

Specifies the column that the Match transformation uses to generate the index key data. Verify that the column that you select contains the type of information that you specified on the

Key Type

property.

Identifies the directory to which the Data Integration Service writes index key data for the current transformation. By default, the property is blank. If you do not specify an index directory, the Data Integration Service uses the location that you set on the Content Management Service.

You can enter a path to the directory, or you can use a parameter to identify the directory. Specify a local path on the Data Integration Service machine. The Data Integration Service must be able to write to the directory.

Identifies the directory to which the Data Integration Service writes temporary data during the index creation stage of identity match analysis. Update the property to specify a location for data from the current transformation. By default, the property is blank. If you do not specify a cache directory, the Data Integration Service uses the location that you set on the Content Management Service.

You can enter a path to the directory, or you can use a parameter to identify the directory. Specify a local path on the Data Integration Service machine. The Data Integration Service must be able to write to the directory.

Determines the amount of system memory that the Data Integration Service assigns to identity index creation. The default value is 400,000 bytes.

If the index creation operation generates a greater amount of data, the Data Integration Service writes the excess data to the cache directory. If the operation requires more memory than the system memory and the file storage can provide, the mapping fails.

Identifies the data source that contains the master data. Specify a master data set in dual-source analysis.

Specifies whether the transformation updates the current index tables with index data from the mapping data source. Select one of the following options:

Update the database with new IDs.
The transformation adds all rows to the index data that do not duplicate a sequence identifier in the index data. The transformation does not update the current rows in the index.
By default, the transformation performs match analysis when you select the option. You can use the Matching Process option to enable or disable the match analysis.
Do not update the database.
The transformation does not update the index tables with index data from the mapping data source.
The transformation performs match analysis when you select the option.
Remove IDs from the database.
The transformation deletes rows from the index tables if the rows share sequence identifiers with 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.
By default, the transformation performs match analysis when you select the option. You can use the Matching Process option to enable or disable the match analysis.

Determines whether the current transformation performs identity analysis.

The option that you select on the Persistence Method property determines the options on the Matching Process property.

Identifies the database that contains the index tables.

Identifies the index tables within the database that you specify.
