This is a blurb from the Adobe web site:
Integrate with Web sites and databases
Acrobat forms can be viewed with Netscape Navigator(R) and Microsoft(R) Internet Explorer. They also work with standard Web server CGI scripts, so you can replace HTML forms with Acrobat forms with little or no change to existing scripts. And with third-party database software and the Acrobat Forms Data Format (FDF) Toolkit, you can link your Acrobat forms to your database systems.
sounds like REALLY advanced development to me!
