Attaching a Match Rule to a Data Model

If needed, click Open Match Rule to open and view the details of the Match Rule.

If you want to attach a match rule with multiple rules to a data model, make sure each match key is mapped to an entity element correctly in each rule within the match rule.

You can select any simple type elements at the root level from a single entity and the entities linked by a foreign key (if any) defined in the previous entity. Note that the survivorship function does not take effect on the elements selected from those foreign key entities.

For an example of defining a match rule with match keys mapped to simple type elements from multiple entities, see An example of defining a match rule with match keys mapped to simple type elements from multiple entities.

Alternatively, select the Use the built-in "Blocking Key" column check box to use the built-in blocking key which has been predefined in the Staging Area and according to which you want to partition the processed data in blocks. A built-in blocking key is defined using a Job (with a single column or the transformation of multiple columns). The Job can connect directly to the database to update this built-in blocking key.
