attribute group cardinality constraint

attribute group cardinality constraint

A constraint on the number of times that an attribute group may be included in the same concept definition or expression.

Notes

• Cardinality constraints are represented by square brackets containing a minimum value value represented as an integer, optionally followed by two dots and a maximum value represented as an integer or as an asterisk *****.

  • If the maximum is omitted then the maximum cardinality is the same as the minimum cardinality.

  • If the maximum is an asterisk ***** the maximum cardinality is unlimited.

• Attribute group cardinality is NOT the same as attribute in group cardinality.

Attribute in group cardinality constraint is defined as:

* A constraint on the number of times that a specific attribute may be included in the same attribute group.
