Documentation

Definition

Specifies how many object instances in in this role can be related to object instances in the related role.

Use

Dependencies

The cardinality when creating relationships is not checked as standard. If they are to be checked, you have to set the the IP_CHECK_CARDINALITY parameter when calling the CREATE_LINK method.

Example

A transit flight can have any number of connecting flights. The other way around, a connecting flight of the connection can be for any number of transit flights. The cardinalities were therefore M:N for the relationship type flight connections.

Any number of replies can be written to an e-mail. The other way around, however, a reply only refers to one e-mail. For relationship type replies, the cardinality is therefore 1:N.
