how do I prefill an xdp/pdf and then submit the completed form to database

I would like to send prefilled data into the xdp/pdf file.

The starting point would be a web page, with a link that directs the user to the xdp/pdf file and prefill that form with some data from the url link.  Then  let the person complete the rest of the form and click on a submit button which would send the form to a url so I can process the data into a datbase.

I did this in the past with Acrobat 5. 

Now I have Acrobat Pro 10 with lifecycle designer.

I am looking for tutorial on this material.

Thanks in advance for any assistance
