Add Rule To Relationship Class (Data Management Tools)

Summary

Adds a rule to a relationship class.

A relationship class is created with one-to-one, one-to-many, or many-to-many cardinality. A relationship class can be defined in more restrictive terms by adding a rule to a relationship class. Once a rule is added to a relationship class, that rule becomes the only valid relationship that can exist. To make other relationship combinations and cardinalities valid, additional relationship rules must be added.

Label	Explanation	Data type
Input Relationship Class	The relationship class to which a rule will be added.	Relationship Class
Origin Subtype (Optional)	Specifies the subtype of the origin class. If the origin class has subtypes, choose the subtype to which you want to associate a relationship class rule. If the origin class has no subtypes, the relationship rule will apply to all features.	String
Origin Minimum (Optional)	Specifies the minimum range cardinality for the origin class if the relationship class is many-to-many.	Long
Origin Maximum (Optional)	Specifies the maximum range cardinality for the origin class if the relationship class is many-to-many or one-to-many.	Long
Destination Subtype (Optional)	Specifies the subtype of the destination class. If the destination class has subtypes, choose the subtype to which you want to associate a relationship class rule. If the destination class has no subtypes, the relationship rule will apply to all features.	String
Destination Minimum (Optional)	Specifies the minimum range cardinality for the destination class if the relationship class is many-to-many or one-to-many.	Long
Destination Maximum (Optional)	Specifies the maximum range cardinality for the destination class if the relationship class is many-to-many or one-to-many.	Long
