Buongiorno a tutti,  
siccome per la mia tesi di laurea ho bisogno di mostrare un diagramma  
uml della mia applicazione Rails, volevo chiedervi di segnalarmi, se  
esiste, un tool in grado di generare un diagramma UML in automatico ed  
eventualmente lo schema ER del database, se è possibile.  
Altrimenti accetto suggerimenti o soluzioni che percorrano altre strade  
Grazie mille!  
Giorgio
