Configuration view
From this view, you can edit the configuration of the tMatchGroup component or define different configurations in which to execute the Job.
You can use these different configurations for testing purposes for example, but you can only save one configuration from the wizard, the open configuration.
In each configuration, you can define the parameters to generate match rules with the VSR or the T-Swoosh algorithm. The settings of the Configuration view differ slightly depending if you select Simple VSR or T-Swoosh in the basic settings of the tMatchGroup component.
You can define survivorship rules, blocking key(s) and multiple conditions using several match rules. You can also set different match intervals for each rule. The match results on multiple conditions will list data records that meet any of the defined rules. When a configuration has multiple conditions, the Job conducts an OR match operation. It evaluates data records against the first rule and the records that match are not evaluated against the other rules.
-
The Key definition parameters.
-
The Match Threshold field.
-
A blocking key in the Blocking Selection table (available only for rules with the VSR algorithm).
Defining a blocking key is not mandatory but advisable as it partitions data in blocks to reduce the number of records that need to be examined. For further information about the blocking key, see Importing match rules from the studio repository.
-
The Survivorship Rules for Columns parameters (available only for rules with the T-Swoosh algorithm).
-
The Default Survivorship Rules parameters for data types (available only for rules with the T-Swoosh algorithm).
Procedure
-
Click the [+] button on the top right corner of
the Configuration view.
This creates, in a new tab, an exact copy of the last configuration.
