Conceptual objects can be defined to adhere to cardinality rules, which specify the minimum and maximum number of child records each parent record in an object must have. For example, a cardinality rule can enforce a relationship that every country record must have at least one state child record, but not more than six.While adding or editing records in a conceptual object, the cardinality must be considered.
For more information about cardinality, see Implementing webMethods OneData.
Note: Cardinality is applicable only to a conceptual object.
