Easy question. Layer diagram?

[Krayol]

Hi - hopefully easy question.  Before EA, I would generally produce a standard layer diagram to indicate the structure of the application packages...you know the sort of thing: data access, object model, business logic,  ui, security, etc.

What would be the best option to represent this in EA?

Many thanks!

Are you asking what kind of diagram you should use?

[Krayol]

Yes.  Which diagram, supported by EA, would best represent this type of system view?

Just in case my description was ambiguous, I'm referring to this type of diagram (taken from the web at random):  http://subpersistence.sourceforge.net/img/layers.png

Hi,

IMHO the most appropriate UML 2.2 equivalent for your layer diagram are package and component diagrams.

Thanks Makulik.

I'll have a look on that basis.

Karl,

Actually in EA the type of diagram doesn't really matter. Apart from sequence diagrams all other diagrams are basically the same thing, with another icon. You can put any type of element on any type of diagram.
(switch toolbox if necessary)

Thanks Geert,

That's an interesting view and quite true.

My aim is actually to have something to present to stakeholders that they would be familiar with.  The layer diagram "ticks all the boxes" since it is understood by everyone (although I appreciate that it's not really UML!).

Hi,

So if you just need it for presentation purposes and the aspect of traceability in your UML model doesn't matter in that context, just use this type of layer diagram you and your stakeholders are familiar with. You could even create a separate document for this (PDF, JPEG, whatever) and simply link this into your UML model.
