What can be considered as the business logic of simple data entry form

Question

Hi all,
I want to separate my applications logic into layers. It is a simple data entry form and doesn't contain any complex business logic. So I want to get this simple business logic to different layer. But the problem is, I cannot clearly identify what are business logic of this kind of simple data entry form.
How do I separate business logic of this simple data entry form to another layer?
any help is appreciated,
Thanks in advance,
Dil.

Suppose that the data comes into your system immaculate from some external system. Imagine that it will go out into some other system. The bits that you would still have to write are your business logic.That's a nice practical definition. Thank you, I'm stealing it.
Also interesting to note that validation falls into that category... say you're recieving data from a magical external source... you still have to validate it.
And of course you'd still have to store it somewhere, ans retrieve it.
Yep, I definately like that definition.
