layered architecture diagram

[EAUsr]

How does one draw a layered logical architecture diagram for a software system using EA?  Is there a white paper on this?

Use packages to represent the layers and put your classes in them. For instance you could create packages for

• Presentation Layer
• Business Layer
• Data Access Layer
• Data Layer

You may need several nested packages within these if you want to break them up further for a large system.
I haven't seen any whitepapers on how to do this in EA. The only one that comes close is by OAD Consulting but thats in the enterprise architecture space.

However if your looking for patterns of layers then if you in the Microsoft camp you may find the following useful

If your in the java camp

Alternatively if you are using another technology then just Google patterns or blueprints for the technology your using.

Hope that helps

We have additionally added a <<layer>> stereotype in our MDG which makes packages appear as simple rectangles. Looks a bit better.
