in reply to reading the hash information from a file

Given that you have "huge data", you will want to use DBM::Deep. This is one of the reasons this module was written. If you have any questions, please don't hesitate to ask me - I'm the current maintainer.
My criteria for good software:
  1. Does it work?
  2. Can someone else come in, make a change, and be reasonably certain no bugs were introduced?
