XI Development , QA , Production Landscap

Hi All,

I need to design a document that shows the XI dev,QA & Production systems. Can anyone tell me where can i find such a image.

Also do we create seperate SLD for development and production or only create one SLD and export that as a file and finally import in the production.

And how do we transport objects from development from dev to QA or production.Is there any other way apart from exporting tbz file and then copy the tbz file and put it in the import directory in the QA server. I mean the way we do in R/3.

Thanks

Sumit
