Export data from pdf created in Livecycle Designer ES4 to a database

Hello,

I have created an interactive pdf using Livecycle Designer ES4.

Now I want to import the data from the pdf into a database in an automatic way.

1.In which format do you recommend to save the pdf data in order to do not loose information and connect this to a SQL database?

2.Is there the possibility to sent automatically the pdf data via a sent button included in the form?

Thank you
