Title: Deployment Diagrams
Post by: NT on June 01, 2008, 08:22:21 pm

I'm a beginner to EA and would like to know if the following is possible or even make sense in UML/EA?

I've created a Device Node (Linux Server) with a nested Execution Environment (Application Server).
On another diagram, I Ctrl drag the Device Node to create an instance. However, I would like a nested instance of the Execution Environment to be shown as well.

Can this be done automatically, or do I have to re-create the child Nodes in the instance diagram manually?

Thanks

Hi'ya...

Not sure that I've got your concern.  But..
Wouldn't an instance of a device / node be the hardware, surely it's just the Execution Environment that would be meaningful as an instance in a Deployment 'Instance' Diagram.

You probably need an addin to do the transform... ( template, model to model thingie ... like transform to C# Model).

Sorry, not the best explanation. Maybe I can explain it better with respect to classes.

Let's say I create two classes, class A and class B. I make class B an aggregate of class A.

Now I create an object diagram and drag an instance of class A and class B onto it. Can EA create a link between the two objects automatically, as suggested by the class model?

Or do I have to create the links my self - referring back to the class model to check consistency.
In other words, can EA enforce or at least check consistency between class relationships and instance relationships.

Thanks.

No, EA doesn't automatically create links between instances of elements that have links between them.  The link between the classifiers only means that the objects could be linked.  (Think of a 1 to 1 relationship between classes A and B.  Now create two instances of A and one of B.  What should EA do?)

Yes, I see your point.

My other question is more 'after the fact'.
Once the instance model has been manually completed, is there any way I could potentially (e.g.) run a script or something, to ensure the instance diagram is consistent with the class diagram?

Thanks

You could run a script...  But you'd have to write one first.
