Perhaps there should be a new category called "Obfuscated Questions" for interesting, compellingly vague questions.

Before even trying to answer, you might want to specify the tools you have to work with. Windows, UNIX, MacOS, Palm Pilot, or Toaster Oven? Do you use, or are you planning to use an SQL database, flat file, drum memory, or wax tablet? Are you using CGI.pm, or have you cooked up your own? What level of experience do you have with Perl? Are you able to install additional modules?

All important pieces of information that are not available, and cannot be deduced from the information you have given.
