Pretty good question, but not one that should be asked here, right off. Look into the Apache::DBI and DBI in general, as well as SQL, etc. You have asked a very broad question, and I'm afraid we don't have that much time.

The tutorials page has some good DBI information, not all related to html forms, but btrott's DBI logging example shows how to submit things to a database (one way).

Look around, play with perldoc, pick up Programming the Perl DBI from O'Reilly, look at DevShed, and do a Google search.

Good luck, and once you get some specific questions, let us know.

Update:

Dear me! I forgot to send you to merlyn's homepage! Go to his home node and click on the link.
