Web Development: One Form or Mulitiple Forms?

I'm looking for opinions on this. I'm about to develop an application in
which users will create documents using form A, and then optionally create
related (not response) documents based on forms B, C, etc. Some of the
information from form A will need to be duplicated on the other forms, and
all the related documents will share a common id number (key). All of this
will be done via web browsers.

I'm kind of new to Domino development, but I've got a lot of experience in
"traditional" programming. In that world, this would be a no-brainer --
I'd create a different file for each form, and I'd link them together as
necessary to show the common information.

But Domino seems to be different, and the web aspect adds another
difference. In some apps, I've seen the developer create one big form
incorporating A, B, C, etc., and just show or hide the different sections
as appropriate. In other apps I've seen the developer create different
forms and duplicate the information across all of them.

Is there a "best practice" here, or is it just a case of "it depends" or
"whatever floats your boat"?

TIA for any thoughts you might share. . . .
