Relationship Base Objects

Relationship Base Objects

A relationship base object is a base object that stores hierarchy relationships. A Foreign Key Relationship Base Object is an Entity Base Object containing a foreign key to another Entity Base Object. A Relationship Base Object is a table that relates the two Entity Base Objects. Foreign key relationship types can only be associated with a single hierarchy.
Only one relationship can exist between two specific entities. If you try to add more relationships between the two entities, the existing relationship is updated instead of a new one being added.
When you modify the base object using the Schema Manager, do not change any of the columns added by Hierarchy Manager. Modifying any of these columns will result in unpredictable behavior and possible data loss.
The following table describes the properties you can configure when you create a relationship base object:
Property
Description
Item Type
Read-only. Already specified.
Display name
Name of this base object as it will be displayed in the Hub Console.
Physical name
Actual name of the table in the database. Informatica MDM Hub will suggest a physical name for the table based on the display name that you enter.
Data tablespace
Name of the data tablespace. For more information, see the
Multidomain MDM Installation Guide
.
Index tablespace
Name of the index tablespace. For more information, see the
Multidomain MDM Installation Guide
.
Description
Description of this base object.
Entity Base Object 1
Entity base object to be linked through this relationship base object.
Display name
Name of the column that is a FK to the entity base object 1.
Physical name
Actual name of the column in the database. Informatica MDM Hub will suggest a physical name for the column based on the display name that you enter.
Entity Base Object 2
Entity base object to be linked through this relationship base object.
Display name
Name of the column that is a FK to the entity base object 2.
Physical name
Actual name of the column in the database. Informatica MDM Hub will suggest a physical name for the column based on the display name that you enter.
Hierarchy FK Column
Column used as the foreign key for the hierarchy; can be either ROWID or CODE.
The ability to choose a BO Class CODE column reduces the complexity by allowing you to define the foreign key relationship based on a predefined code, rather than the Informatica MDM Hub generated ROWID.
Hierarchy FK Display Name
Name of this FK column as it will be displayed in the Hub Console
Hierarchy FK Physical Name
Actual name of the hierarchy foreign key column in the table. Informatica MDM Hub will suggest a physical name for the column based on the display name that you enter.
Rel Type FK Column
Column used as the foreign key for the relationship; can be either ROWID or CODE.
Rel Type Display Name
Name of the column that is used to store the Rel Type CODE or ROWID.
Rel Type Physical Name
Actual name of the relationship type FK column in the table. Informatica MDM Hub will suggest a physical name for the column based on the display name that you enter.
