General Board / Re: Diagram Relationships

« on: February 24, 2003, 11:16:46 am »

Hi Stephen,

I am not sure i can get your meaning exactly. Do you want to setup milti-columns foreign in EA schema diagram? If so, I can help.

Just right clike the mouse with the cursor on the target table, select operations, then input the FK name and select the stereotye "FK", save it. Then you can add multi columns of the table to the definition of the FK(clike 'columns' sub pannel).

If it is not your meaning, pls let me know.

Hi Tjerk,

Yes, you are right. Which procee you use depends on situation. Over emphisis process could kill interest and efficiency.

Thanks for your help.

General Board / EA Application Development Process

« on: February 17, 2003, 01:46:22 pm »

Dear all,

Analyzed and generated form availalbe resources, I got the general application process with EA by my own understanding.

1. Inception (Analysis and Basic design)
Tasks in this phase include determining use cases and actors.

2. Elaboration (Detail design)
Use cases have been fully detailed and accepted by the users, the class diagrams are complete when this phase is over. In other words, this phase is complete when the system is designed, reviewed, and ready for the developers to build it.

This phase is the detailing of the system requirements; the use case mode might require updating. As the follow of processing is detailed, Sequence and Collaboration diagrams help the flow. Class diagrams and some state diagrams should be created.

UI and test case design can be parallel process in this phase.

3. Construction (Coding)
Task in this phase include determining any remaining requirements, developing the software, and testing the software. No any new design decisions could be made because the software has been completely designed during elaboration phase. As code is completed, it should be reviewed by quality assurance to ensure that it meets design. If any new attribute are added, the new code should be updated back into EA model through reverse engineering.
(Issue: if component diagram should be created in this phase. Rational rose can generate skeletal code from it.)

More programmers could be added in if possible.

Construction is over when the software is complete and tested.

4. Transition
The transition phase is when the completed software product is turned over to the user. The tasks in this phase include completing the final accepting test, user documentation, preparing for user training. The Requirement specification, Use case diagrams, Class diagrams, Component diagrams, and deployment diagrams must be updated to reflect any final changes.

It is important to keep these models synchronized with the software product because the models will be used once the software product goes into maintenance mode.


I will listen to all advice from you all.

Thanks,

Robert Song

Hi Rich,

Thanks for your analysis.

Yes, the class operations can be automatically modified by your action at message in sequence diagram. It is very convenient for you completing class diagram when designing object interactions diagram.

But in my imagination, for example sequence diagram should be used to generate skeletal code by the messages sequence. If it can do that, the sequence diagram must be more useful.

Thanks all.

Hi, Takeshi,

I have done generating code from class diagram and reversing coding from my application to EA. I can generate DDL coding from schema diagram as well. But exactly I haven't figure out sequence, collaboration, and component diagram coding generation using EA. My friend told me Rational Rose can do it. But...

Anyway, Thanks for your reply.

Hi Frank,

Yes, You are right. The reason of the error is read-only file.

Thanks a lot,

General Board / EAP file open error

« on: January 21, 2003, 10:09:31 am »

Dear all,

An urgent problem to ask all.

Who ever happened following problem when opeing the .EAP file:
" The microsoft Jet database engin can't open the file 'D:\..\.eap'. It is already opened exclusively by another user, or you need permission to view its data"

Someone can tell me how to deal with the problem. Actually, No other user is opening the file.

Thanks,

Robert

Uml Process / Re: UML and .NET Framework / vb.NET

« on: February 18, 2003, 10:37:04 am »

Hi Sergio,

I am using EA and VB.NET/SQL Server to develop an application. But regretly I could not find any book about VB.NET using UML.

What i am doing just using previous vb6 experience, combining with new .Net feature(.net has much more different from visusal 6 version). From EA model, I can get the class definition source code, DDL data definition source and coding logic from some dynamic view diagram.

Hopefully it helps.

Robert
