Question on mileage system

[Mandy Yan]

It mentions that the mileage system will not be rewrited. However, there should be a web interface for customers. May I ask how this requirement is incorporated into the diagrams? It seems that it cannot be represented in class and sequence diagrams. Is it required only in Component Diagram?

[Theodore Casser]

You are correct - the requirements state explicitly that you may not rewrite the mileage system (as, IIRC, they just had it written). It's up to you, though, how you carry through the requirements applied to using the system - if you search this forum, you'll find some discussions on the matter.
