#18173 — Good notation for showing MVC interactions (i.e. Django)

Good morning,

I'm developing various websites and functionality to cater to various
different use-cases up in Django.

Is there a good notation for showing what behaviour is at each stage,
i.e. using swimlanes?

I use BPMN 2 notation for everything, but I feel I am overusing this,
and that there would be a more suitable one for this.

Thanks for all suggestions,

Alec Taylor

Swimlanes?  You mean like http://tinyurl.com/caqf3h5 ?  Never used them.  
Never used BPMN either.  I've found most of these heavyweight modeling 
tools to be more of a hinderance than a help.  People get all wrapped up 
in making pretty diagrams when they should be spending more time writing 
code.

I find that when thinking something through at the whiteboard with 
another developer, the most common diagram I'll use is a UML sequence 
diagram.  I drew one on the wall just yesterday.  Here's one 
(http://www.panix.com/~roy/SongzaSessionHandoff.pdf) I did up a bit 
fancier a while ago while working through a gnarly design problem.

As with most things in UML, I find the basic concept useful and don't 
sweat the details of what different shaped arrowheads mean or what 
flavor of rectangle I'm supposed to be drawing.

An example of a BPMN2 diagram with swimlanes, which I created for a
project: http://i40.tinypic.com/262r6nr.jpg

What I am looking for is something suited towards showing architecture
bounds and the interactions between each section of MVC.

That's a good notation, and one which I will use for RESTful API modelling.

I sometimes use use-case diagrams and quite rarely also use class
diagrams and ER Diagrams.

I use BPMN2 to show logic to both technical and non-technical team-members.
