 Question Schema E-R progetto

Salve a tutti,

Vorrei sapere se qualcuno di voi ha collegato l' entità esercito con l' entità città, e saper come rappresentare nello schema E-R gli spostamenti e l' ubicazione degli eserciti nelle città.

Poichè ho un dubbio che si possa creare un ciclo tra Nazione - Città - Esercito.

Grazie
