DTV11 — DTV Issue: figure 8.11 Duration Operations

Open Closed All
  • Key: DTV11-71

  • Summary:

    (See red circle in attached diagram). Figure 8.11, Duration Operations, shows that each instance of the class 'duration' participates in exactly one instance of the class 'duration1 equals number times duration2' as role 'duration1'. Clearly this is false. For example, the duration "4 hours" is the result of both "2 times 2 hours" and "4 times 1 hour".

    Note that the UML diagrams show that instances of each role can participate in any number of instances of the reified classes. For example, see "duration1 equals duration2 minus duration3".
