DB in Creator or Report?

Hi, I am writing an application to collect data using form (with a lot of scripts inside) and show sophisticated reports and graphics.

I also need Customer Portal Function and SMS integration.

As far as I understand there are at least 2 scenarios:

1) the DB and the Form is in Zoho Creator and the reports are made in Zoho Reports and shown and embedded in Zoho Creator pages or in web pages.

2) the DB is in Zoho Report and the Form is in Zoho Creator. The Reports are in Zoho Report and are shown and embedded in Zoho Creator pages or in web pages.

Is there something wrong in my understanding?

What is the best solution in term of price/performance?

I am not an html expert but I can create complex form using deluge.

What is Your suggestion?

Tks,

Pippo
