Hi Hitry,

Congrats for a great score. I have just started preparing for Part 2. Any tips for me?

Which UML tool you used? Most of them are eval versions. Is there any completely free/open-source one? Any plug-in for Eclipse?

Do you need any knowledge specific to airlines/travel?

Thanks,
Lokesh.

Hi Lokesh, thanks for congratulations.

I used Sparx Systems' Enterprise Architect. We have a license at work. I think it's a very nice tool.

As to freeware tools, there's Jude Community Edition. It's also good, but not as good as the EA.

I am not very familiar with Eclipse since we use Oracle OC4J and IntelliJ Idea as IDE at work. There are UML plugins available for IntelliJ, but they are not very convenient.

Specific airline/travel world knowledge is not required for this assignment. However, if you have trouble interpreting the BDOM (like I initially did) you might want to spend some time playing with one of the online ticket-booking systems that many airlines offer these days. As to me, I used the website of Dutch railroads at www.ns.nl. Although they deal with trains rather than planes, I found that their procedure is rather relevant to this assignment.

Congrats! Wonderful news and a great score to boot.

Congrats,Hitry!

How did u present your component diagram? I'm sticking on the component diag for a long time
How did your seq. diag in the detail? component-based or class-based?

thank you in advance

Hi Durren,


my component diag is pretty much in line with Cade 1st edition:

1) all EJB

2) Integration tier (DB+legacy)

3) Front end: all JSPs/Swing screens + some extras...

4) Some special components (eg. ServiceLocator).

This should do it!

Congrats Hitry!!Its a great score.

Could u pls tell me if u had shown the generalization(inheritance) relationships in your class diagrams.

I have seen people writing about other relationships(association, dependency, aggregation, composite etc) but have never seen any post saying that the generalization was shown.

The example in Mark Cade too doesn't show generalization .

If you too had not shown generalization then why ?

Pls throw light and clear my doubts.


Thanks
Pankaj

[Hitry Mitry]

Hi Pankaj,

I did show inheritance in a couple of situations where I wanted to emphasize this sort of relationship between classes. But I did not show it consistently throughout the diagram.

From my experience, this is how UML is to be used: you show things that are worth being shown and omit those that aren't. You don't show unimportant things just because you have shown something similar elsewhere on the diagram. I am under impression that Sun graders also share this view.

Congratulations!
I got a question about whether I have to list every actual classes in the control logic, such as xxxRequestHandler and yyyRequestHandler (equivalent to Struts Action classes) in the components diagram, or I can simply use one generic compoent (such as RequestHandler) to represent them in COMPONENT DIAGRAM. Further if I have to list all of them, should (and how can) I show the generalization relationship between the abstract base RequestHandler and individual class (following the command pattern) in the COMPONENT DIAGRAM?
I'd very much appreciate your response. Thanks.

Hi Alex,

I think you never have to "list all of them" . I would only show things that are important. Again, the component diagram is designed to depict components, i. e. "physical" entities, i. e. those whose lifecycle is well-defined, such as, for example, EJB. I would not recommend cluttering the component diag with inter-class relationships. After all, there's the class diagram specifically for that purpose.

Hitry,thanks for your good advice!
now i got some questions:
1.according to your words, DB as resource tier was presented, right?
2.Did you present yr component diag based on logical tier or package?

thank u in advance!

Hi Duren,

1) the DB itself is not very interesting. But you probably need a tier to abstract it and make it available to the other tiers. This is what I meant in my original reply to you.

2)Sorry, didn't quite get the question. Yes, there are (logical) tiers on the diagram, as I mentioned. If you talk about the way the individual components are shown, I would not huddle them into a package but just show each individual component wherever possible.
