Use data of own database in facebook application

I wa开发者_开发百科nt to develop a Facebook application which shows the data from database from my own server.

I have found one question here : Can you use your own database for Facebook applications?

But like above question I don't want to use iFrame to show my content on Facebook application.

Any solution for this as, I am new to Facebook application development.

Edit:

Simplified version: I have a page in my server which generate xml feed of the product. So can I read this xml feed url in facebook Application?

Almost all applications use an iframe to display the actual app, I don't think you'll be able to avoid it. What you put into that iframe however is entirely yours. It runs from your server, and so can use whatever back end you prefer.

Why don'T you want to use iFrame? FBML & Iframes are only ways you can show your content with !
