Re^3: Perl for payment processing

"basically its a case study and I should investigate the best ways in perl"

In your first post you tell us a high level requirement that has been given to you, and that you're new to perl. I suggest you take the time to learn the basics of the tools you have been told to work with before doing going any further. Just asking other people isn't a case study, or any investigation on your part. Tutorials/http://learn.perl.org.
