Failed in component diagram

[binu alex]

Hi

I failed in component diagram .and working on the resubmission .i have got the comments as "confusion between layers and tiers and no demarcations". Are there any good samples for component diagram ?

There are two ways you can represent your component diagram, viz
[1] Have one component diagram per use case, so it will be 3 or 4 depending on number of use cases(Refer worked out example in Mark Cade and Simon ).
[2] One component diagram for all usecases ( Refer chapter 9 of Cade and Sheil book ).

In fact, I have done both versions in my assignment.

Bottomline, does not matter whether you use 1 or 2 or both in the above, you should clearly seggregate the Tiers/Layers, if you use color for your diagram, then clearly state color coding explanation ( suggestion by cade and sheil in chapter 9).
