Now let's see how object oriented analysis might work
in practice by considering the following requirement for an online
shopping website. The requirement says that users can add
more than one item on sale at a time to
a shopping cart. So, looking at this requirement I
would like you to tell me which of the following
elements should be modeled as classes. And the elements
are: item, sale, shopping cart, time and user. So mark
all that apply.
