Fields used to identify cardinality
The cardinality of a line in a data model can be specified using a text identifier:
From association field
A database field that provides a text description of the cardinality of the end of a line.
To association field
A database field that provides a text description of the cardinality of the beginning of a line.
The cardinality of a line in a data model can also be specified by a numeric identifier:
From association number
A database field that contains a five-digit numeric value corresponding to the value of the From association field (see above).
To association number
A database field that contains a five-digit numeric value corresponding to the value of the To association field (see above).
These are the association numbers the reporting system recognizes:
