are parameters compulsary in an url pattern?

Dear all,
I just wish to know if I must have all the parameters from my form as a
part of the url pattern?
I need to use only the request so was wondering if that is the case?
I have seen tutorials and all of them come with url parameters
I don't need a url like /articles/2013/03 etc.
I am writing a accounting/ inventory system and don't need a blogging
kind of application or a news room kind of stuff which Django is mostly
known for.
My forms will contain all the data and I can access all that in a view
through the request object I guess?
so a pattern like r(^setaccount'), views/account/setaccount must work.
is this correct or do I always need to pass parameters?
Which is the best time to use parameters apart from the request object?
Happy hacking.
Krishnakant.
