Congratulations! It's an excellent score.

When did you submit your project? How long did it take to get the result? I submitted four weeks ago, no news yet.

Thanks
James

[Sanz Vai]

Congratulations Harish!

Can you give me some ideas on Assumptions file?

Also, what do I need to prepare for Part 3 questions? What kind of questions and hints on answers?

Thanks

[Ramon Gill]

Harish,
great score, fabulous work.

Can you tell us a bit more about the diagrams?

Class - did you include attributes, operations, navigation? How many classes?

Component - Did you include a framework like struts?

many thanks,
Ray

James,

The assignment submission date was June 9, 2004. I wrote part III on the same day. The result was out today (July 12, 2004).

You should expect your results soon. I wish you good luck.

Take Care

Thanks Ray !!!

I kept my diagrams simple and easy to understand.

CLASS DIAGRAM:

My Class diagram had approximately 20 classes. It was an extension of Business Object Model. I extended it based on my design modules. For example, a Customer can be extented with Account and Account can be extented with ContactInfo and ContactInfo can further be extended with Address class. Similar approach can be taken for Itinerary module. Ofcourse, I did provide RELEVENT attributes and methods of the class. I used Composition, Aggregation, Navigation, Role and Mutiplicity wherever applicable. I did not use any stereotype in class diagram. However, I put a lot of notes about how the particular class will be implemented. For Example, an Account Manager class had a note attached to it with the description that it will be implemented as Stateless Session bean in J2EE technology.

COMPONENT DIAGRAM:

I grouped together all the components in packages based on the logical tiers to reduce the cluttering. For example, Swing components will be in the Client-Tier package.
This diagram is the place where you'll show different design patterns that you want to use. I have used J2EE design patterns heavily. I did not use any framework. It was the simplified version of petstore application.

Hope this helps.

Good Luck.

Harish,

Congratulations! It's an excellent score.
One question for you,if I provide the relevant method in the class diagram,whether I can use short phrase to depict the message in the sequence diagram.Thanks!

[Ramon Gill]

Harish,
Thank you for your responses to my diagram questions. I am mostly worried about the class diagram, and your comments have been very helpful.

good luck,
Ray

[Luciano Queiroz]

Did you aldo represent the relationships among entity beans inside the component diagram?
For example, did you link Customer with Account? Account with ContactInfo?

Thanks Jacky,

In Sequence diagram, I used Component as classifiers instead of Object/Class, for the same reason that I didn't want to provide actual method names. I used short phrase to depict the message exchanged between components.

Hello Sanz,

DOCUMENT:

My document was much more than just assumptions. It looked really professional and was easily navigable. I don't know whether I can talk about that in details but I'll provide you some guidelines to write it. I have started it with very brief introduction of how I am going to solve the given problem e.g. How J2EE technology will help to address requirements both functional and non-functional. In another paragraph heading, I described in just 2-3 lines, various application modules e.g. Manage User Account, Flight Booking etc. etc. My next heading was 'Application Design' with subsections of 'Design Goals', 'Application Tiers', 'Design choice and decisions' and 'List of J2EE Design patterns used'. In 'Design Goals', you can mention that your goal is to fist fulfill function and non-function requirements, and second, support multiple client types. You can also mention that your goal is to use the proven and tested design and code by using various design patterns. In 'Application Tier', you can divide the application in logical tiers. I just mentioned the tier names e.g. Client Tier, Web Tier, EJB Tier and EIS Tier. In 'Design Choices and Decisions' subsection, you might want to provide your various decision about your design in different modules. For example, you can say why you are using 'Fast Lane Reader' pattern instead of using Entity Beans for searching flights. Also about your choice of patterns for specific functionality. The final section in my document was 'Deliverables' with subsection of 'List of Assumptions', 'Link to Class diagram' along with digram description, 'Link to Component diagram' with description and 'Link to each sequence diagram' with description.
I liked my document as I was able to describe everything in bulletpoints rather than the whole story. I used MS Word to create the html document.

Let me know if you still have any questions.

Hi Harish,
Congratulations on your fine efforts ! I had a question. Did you ever feel the need to change the business model (associations, relationships etc )during your design phase?

Would appreciate your insight on this.

Thanks,
Parag

Ooops. Forgot to mention about part 3 in my previous reply.

There are exactly 4 questions in part 3. Questions are related to system level requirements e.g. What mechanism did you use for xxxx? Another question was related to the previous one e.g. Why did you use such mechanism?
I would suggest you to read all questions before replying, because some questions are inter-related and you don't want to repeat your answers.
Based on my experience, I would suggest not to worry about part 3.

[James J Xu]

Hi, Harish,
Excellent score. Congratulation!

Would you tell us how many sequence diagrams you have? Should we follow the instuctions to have a sequence diagram for each use case?

many thanks,

No, I did not feel any need to change the BOM. Just extended it for my Class Diagram.

No, I did not draw any of the dependent objects. Rather, I attached a note to Customer component with the description that it implements Composit Entity (formerly Aggregate Entity) design patterns with Account, ContactInfo etc. dependent objects.
You may find detailed information about this pattern at

Congratulations Harish for an excellent score.

I have few doubts about the assignment if you could clarify

1. Did your class diagram have private identifiers or only public ?
2. Did u define attributes and methods too for all diagrams?
3. What references did u use for creating the component diagram .. Any helpful resources/links u referred .. I didnt find much yt for component diagram
4. Did u create any additional diagram like package and deployement. ?
5. Did u use sub systems in class diagrams ?

Is it all right duplicating information by dog ear notes (design diagram notes) and putting it down in the document as well as for clarity and document flow.

Thanks

Harish,

Could you tell me where you checked and found your part II & part III score?

I got my certificate in the post office mail today. But I checked on http://www.certmanager.net/sun_assignment/, click on the "Test History" button after login, I still do not see the result. I only saw my part I test result there.

Thanks

James,

It sounds strange. My results were posted on the http://www.certmanager.net/sun_assignment/ only. The exact same path as you mentioned above. I think, you should send an email to Sun/Prometric for inquiry.
Well, Congratulations for passing the exam . How much did you score?

- Harish

[James Wang Ye]

Harish,

Thanks.

I don't know my score. The mail I received does not have the score, only a certificate and a congratulation letter.
That's why I try to find it online.

Hello James,

Its funny to know that I have put a lot more efforts in Sequence diagram than other two diagrams, but lost the only mark there. :roll:
Well, I had 10 Sequence diagrams. Yeah, you heard right..Its TEN. Here is the break-up

- 2 Diagrams : Just to explain how MVC will work for 2 different clients (Web and Swing)

- 2 Diagrams : For 'Login' use case. One for each client type.

- 6 Diagrams : One for each Use case. These diagrams shows the core business logic in client-independent manner.

All Sequence diagrams started with Use Case description. This description was placed at the left margin of the diagram. In this way, it is easy to map the action flow with the use case.

I know that people have scored 100% on sequence diagram by providing just 4 diagrams. It is all up to you.

Best Regards

Harish,
Thanks for the response.
Some use cases include alternative flows, like "Pay for Itinerary" use case has a basic flow "pay with credit card" and an alternative flow "select award travel". How could we model these in one sequence diagram?

The version 2.0 of UML 2.0 adds several useful concepts/notations to illustrate alternative flow, iterations, ... for sequence diagram.
Unfortunately I never see a case tool supporting the version 2.0 of UML although this release is one year old.

Renaud,
Thanks. I am using Rational Rose tool to model the sequence diagram and can't find it support alternative flow. Should we create a separate sequence diagram for basic flow and another one for alternative flow?

Dhiren,
Sorry for the late reply. Just got caught in work. Here are answers to your questions -

1. Did your class diagram have private identifiers or only public ?
ANS: Both.

2. Did u define attributes and methods too for all diagrams?
ANS: Only relevant methods and attributes in class diagram.

3. What references did u use for creating the component diagram .. Any helpful resources/links u referred .. I didnt find much yt for component diagram
ANS: Check out - http://www.agilemodeling.com/style/componentDiagram.htm

4. Did u create any additional diagram like package and deployement. ?
ANS : No.

5. Did u use sub systems in class diagrams ?
ANS: No.

Excellent score!
I have a question regarding your component diagram. You mentioned including components for the Java app in your component diagram. So far, I only included components for the web app, such as JSPs, Servlets and EJBs in my component diagram. Wouldn't it look redundant if I include presentation layer components for the java app? How did you handle the problem?
Thanks for the help.

Tomas

Congrat! Excellent.

I wish I had talked to you earlier for some tips in the assignment.

Hello Tomas,

The most important thing to remember is to keep your diagrams simple and easy to understand. As you know that one of the objective of UML diagrams is to communicate the solution effectively with designers, team members and business analysts etc.etc.

Based on the same lines, here is what I did in Component diagram -

In the 'client-tier' package, I had two subpackage (One for each type of client). To make it simple, I just put only ONE component in each package and attached a note containing all screen names that the system will have. In this way, you can avoid putting so many components (one for each screen ) in your component diagram without loosing any information.

And ofcourse, your core business logic will be implemented in EJB-Tier that will be used by both type of clients. That means, there is no duplication there. You just have to use different business delegates that will delegate the client request to EJB-Tier.

Hope this helps.

Harish, for the class diagram, did you use dependency relationship?

Thanks.

Harish,
Do your both type of clients interact with web-tier? Or only web client interacts with web-tier while swing client interacts with EJB-tier directly?

Harish,
Thanks very much for your reply.
Did you use the Mark Cade book as a reference? I am asking this because the component diagram examples in his book do not contain any packages. They contains indiviual JSPs and servlets, etc. This is what my diagram is based on. Since you had a perfect score, I am not sure what to follow now.
Did you apply the same approach to the business-tier by specifying EJBs only in a note?

rgds,
