General Board / When to add a property and when to associate

« on: September 14, 2004, 11:18:27 pm »

Hi!

When drawing a class diagram I either can add a property, lets say of MyPropertyClass or I can add a association to MyPropertyClass. What's the difference and when should I use either one of them?

Thanks!

General Board / Re: Can't add return messages from a called object

Pab,

Thanks for your answer. That explains an the other question I asked the other day, about why life lines are broken. If I do it the way your say the life line on the caller object is solid until the last message on the called object returns.

Thanks,
Henke

Should't the return arrow from SalesProjectDALC end at the GetSalesProjects lifeline?

General Board / Can't add return messages from a called object

Why isn't it possible to have return messages from an object that has been called, see picture?

General Board / Why is lifeline broken when adding New message?

« on: June 08, 2004, 07:30:18 am »

If you have an object that sends multiple messages to other objects after each other, the lifeline between the messages is solid. But when I send a New massages (a message with lifecycle set to New the lifeline is broken.
Is this correct?

General Board / Adding references to other object i.e. Actors

« on: February 11, 2004, 04:09:23 am »

In my use-case view I have a package containing all actors in the system. I would like to use this actors on my use-case diagrams and so on. How do I add a reference from the actors package to my diagram? I don't want to create a new actor on every diagram and if the actor in my actor package changes it should change all my referenced actors.

Thanks!

Uml Process / Where to put the domain model

« on: April 30, 2004, 01:16:35 am »

Hi
I use the EABase.eap as the model project when starting a new project.
If I look in the documentation on the Sparx-Web I found some sample where they have put the Domain Model in the Logic View. But in there EAExample-project they have put it in the Business Model. Where is the best place to have it?

Are there any other model projects (like EABase.eap) that can give som info here?

Thanks!

Uml Process / Is an external data base an Actor

« on: May 10, 2004, 03:00:41 am »

Hi
I'm modeling a system, "A", that should be able to (among other things) import customer information from an other system "B". The A system will be able to access the data base of the "B" system directly not through any interface in the "B" system. Should I model the "B" system as an actor to the "A" system, orh should I just write in the use case description that the system is importing data from an external data source?

Thanks in advance!
