MCS-270 Discussion Questions 1: Conceptual Modeling
February 12, 2001
The following questions all refer to the POST conceptual model from page
116 or 129 of the Larman text. (Either version will do.)
-
The multiplicity is missing from the ProductSpecification end of the
association with Item. What should it be? Why?
-
What do you think about the Described-by association between
SalesLineItem and ProductSpecification: Is it appropriate to include
this association? Why or why not?
-
The Captured-on association between Sale and Post is shown as 1-1.
Two possible readings for "captured-on" are "was captured on" and "is
the current sale captured on." For each of these possible readings,
either explain why the 1-1 multiplicities make sense or say what
alternative multiplicities would be appropriate.
