Class Diagram (44 maximum) ............................... 42
Component Diagram (44 maximum) ........................... 29
Sequence/Colloboration Diagrams (12 maximum) ............. 10

I guess I saved myself a $150 re-submission after all I know my solution was functional enough for real-life implementation but the submission itself was half-baked as I had to rush through preparing the documentation - the score is not at all disappointing considering how appalled I was when I reviewed my submission a couple of weeks after I submitted it.

Class Diagram - definitely did not deserve 42/44 - it had at least 1 glaring error and a couple of ambiguous relationships apart from being very convoluted in the way it was laid out. Frankly, developers would kick me if I gave them a Class diagram like the one I submitted I had also changed the BDM quite significantly (removed relationships, introduced new classes, added new relationships, modified cardinality, modified requirements but I explained everything in detail, so maybe that helped). The original requirements are c-r-a-p - sorry, but that's the harsh truth. I don't mind if requirements are vague or ambiguous, but if they are contradictory, you bet I am going to fix them before attempting to architect a solution for them!

Component Diagram - I don't blame myself for this debacle! I somewhat followed Mark Cade's examples as well as the suggestions from the folks here. However, I honestly wouldn't use Cade's paradigm for drawing Component Diagrams. I've reverse-architected legacy systems and I think I have an excellent understanding of what Component Diagrams are and what purpose they serve. What I saw in Cade's book might actually be applicable somewhere - but not in any of the workplaces I have been in.

Sequence Diagrams - this was a bit puzzling to me because my sequence diagrams were perfectly functional. Perhaps I gave too much detail, but I know for sure that my sequence diagrams will result in a system that fully meets the functional requirements. I did use option and loop interaction frames, so I wonder if that took some points away.

I submitted 1 Class Diagram, 1 Component Diagram and 8 Sequence Diagrams.

Class Diagram had 18 classes - actually, it originally had only around 14 - I forced myself to tack on a few more because I got nervous seeing people submit 30-35 classes :roll: Did you guys show a class for every variable or something Followed Cade style and showed the service classes also. In the real-world, I would show much less detail.

Component Diagram had 26 components - in retrospect, I should have had at least 2 more components for the external systems - at the time I felt they were outside the scope of the architecture, but now feel they should still have been represented. I just had notes to indicate the presence of those systems. The components were laid out by tier and the Application Client was also represented in the diagram. But hey, with 29 marks, feel free to ignore that I even had a Component Diagram

Sequence Diagrams - 1 for Web Request and 1 for each Use Case. Showed both Customer and Travel Agent flows in the same diagram using opt interaction frames. I didn't have a sequence diagram for the Application Client - frankly, I just didn't know how to do it - app client development is not exactly my strong point and nor am I particularly interested in it - I just fail to see the value in a stand-alone app client.

Actually, I spent a lot of time tightening the flow of messages, the way I would in a real implementation - I would be very satisfied with this effort in the real-world, never mind what Sun thinks

I submitted one document per diagram, explaining the diagram (yeah, I know it defeats the purpose of using UML to a certain extent, but since I was doing so many things outside my comfort zone, I felt obligated to write these documents). I submitted 3 additional documents - Software Requirements Specification (I even changed the Use Case Model and put that in my SRS!), Assumptions and Architectural Decisions.

On the whole, if I had to re-do it (which I thankfully don't!), I would probably structure my submission better. My solution was fine, IMO, but the submission was a travesty of my professionalism and I do feel bad about that. Given that fact, I am quite happy with 81%, perhaps even a tad embarrassed

Hi Sri
Congrats on clearing. As long as you have cleared it and you are satisfied that the design which you have given would solve real world problem, it feels good.I also don't know what the sun expects but they I think would like to see more theoritical and pattern usage than a practical solution.
Few queries Sri.
1. Did you displayed the domain model classes in sequence diagram as entity bean or followed Cade's pattern and left them out ?
2. Did you had any architecture or the displayed complete nine yards ?

Congrats Sri

Which UML tools you used? And what is the version of UML you used?

1. I showed the entity beans in the sequence diagram

2. I presume you are asking if I used any framework...like quite a few other people here, it was a watered-down version of Petstore WAF - but I gave details about every component in the framework.

Jude. I believe my Component Diagram was 1.x and my Sequence Diagrams were UML 2.

I used a lot of design patterns - actually, the assignment was very helpful in refreshing the concepts of some of the design patterns that I haven't used frequently - so I doubt that design patterns were the issue for the loss of marks in the component diagram - either UML 1.x had to do something with it or I just didn't reach far enough in presenting Sun's idea of a component diagram - what I submitted definitely was not my idea of a (good) component diagram either

Congratulations Sri,
Great Job !!!
You are HERE! The other map is obviously wrong. Better confirm with this tiny ad:
