In order to configure match rules for these kinds of relationships, particularly many-to-many relationships, you need create a separate base object that serves as a

relationship base object

to describe to

Informatica MDM Hub

the relationships between records. You populate this relationship base object with information about the relationships using a data management tool (outside of

Informatica MDM Hub

) rather than using the

Informatica MDM Hub

processes (land, stage, and load).

You configure a separate relationship base object for each type of relationship. You can include additional attributes of the relationship type, such as start date, end date, and other relationship details. The relationship base object defines a match path that enables you to configure match column rules.

Important:

Do not run the match and consolidation processes on a base object that is used to define relationships between records in inter-table or intra-table match paths. Doing so will change the relationship data, resulting in the loss of the associations between records.
