Logical to Physical Synchronization: the Parts (UML)
Synchronization of parts is available by default with the new UML formalism. See Logical Data Modeling Options.
The result of the synchronization is determined by the combination of the Whole/Part link (None, Aggregation, Composition) and the Multiplicity defined on the part.
For more information on parts, see The Parts.
