UML vs CDIF Notation(Multiplicity vs. Cardinality)

UML uses Multiplicity where CDIF and earlier models use [Outer] Cardinality:

• UML uses [0..M] and calls it multiplicity; the CASE Data Interchange Format (EIA/CDIF) standard uses 0:M and calls it cardinality; both have the same meaning and denote the same interval range.

• 0 and M are called, respectively, the min and max cardinality or multiplicity.
