Grade: F
Score: 60
Comment: This report shows the total points that could have been awarded in each section and the actual amount of points you were awarded. This information is provided in order to give you feedback on your relative strengths on a section basis. The maximum number of points you could have received is 100, minimum to pass is 70.
Class Diagram (44 maximum) ............................... 34
Component Diagram (44 maximum) ........................... 23
Sequence/Colloboration Diagrams (12 maximum) ............. 3

I followed closely the case study by Mark Cade (Sun Certified Enterprise Architect for J2EE Technology - Study Guide)

The class diagramm is not too difficult and i am able to improof it.

The component diagrams in this study guilde look very simple
(<<JSP>>Form - <<servlet>>Controller - <<SLSB>>Processor - DAO).
Obvioulsy this is *not* (or not enough) what Sun expects.

As for the sequence diagrams, i don't understand the poor score not at all. It was much more work than the class diagram.

Please help me, i am desperate...

Thank you!

I'd disagree that Cade's examples aren't in the direction the graders are looking, as mine were drawn reasonably along the same lines as those in the guide and I did pass (admittedly not with the greatest of scores, but any score you can walk away from...)

Take a look at your diagrams and see where they could be imporved, where you could add some more detail or refine them further. You might also have a coworker or other colleague with experience doing software architecture take a gander at the diagrams to see if there's anything that you might be overlooking after staring at them for so long.

And, don't give up! You're so close!

Yes, I documented the assumptions, however in a rather short form.
The document including all diagrams is only 13 pages.

Read Cade's book again and again!

You will find the difference betwenn yours and Cade's or you should not have failed otherwise.

Hallo Lukas,

this is probably a very silly question I ask: Does your design meet the requirements ? After all, that is the most important point about the assigment, meeting the functional requirements and the Quality of Service.

I ask this mainly because of the low sequence diagram score. Is the control flow too simple/too complicated/unclear ?

Regards,

Hi Lucas,

It's really unfortunate that you missed the passing score by just 10 points. Dont give up, I am sure you can clear it next time.

What would be helpful for others to understand the exact reasoning for the scores is to provide the number of elements in each of your diagrams. For example, ClassDiagram - x, Comp.Diag - y, Seq-Diag1 - z , Seq-Diag2 - z2 etc.,.

This would help us understand if you showed too less or too much detail.

To conclude, Cade's appraoch is good, but not the end of the world. You will still need to make sure all the requirements are met and all the required classes/components still make in to the used appraoch.

Good luck next time.
