Between this and your original post, it sounds like you've been given a task at your paid job, and before even doing any research or testing at all, you've come here to ask us to do your ground work for free (all without knowing anything about your business, processes or overall infrastructure).

Please take a look around the CPAN, test out some code, then perhaps ask about specific issues you may be having.

"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.
