title: How does Infopath forms routing work (ie an Expense Approval form)? Is a PKI required?
body: <p>I don't have an understanding on how the whole InfoPath product works.  I know it can save data to Sharepoint.  But here are a few bits of information I'm confused about:</p>
  
  <p>If someone saves an Infopath form to SPS, is the entire form saved, or just the data?</p>
  
  <p>How would an approval scenario work?  </p>
  
  <p>My employer wants to use as little code as possible for each form.  They are currently using PKI that requires the end user to submit the form (to Access DB), sign the form, then save the form.  I know this isn't ideal, but I don't have enough background to tell them what to do instead.</p>
