[Zope] Data from forms into a database - how?

Hello! Don't laugh at me - this is probably a very simple thing to do, but as I'm new to zope and can't find description of how this is accomplished I seek your help. I get data out of my database (MySQL) by querying, but how can I have data collected by forms showeled into the database? Appreciate any help I can get! Sture Lygren
