You stated three requirements:
  1. I have got a tremendous amount of data that I need to have accessible at my program's finger tips at any time while it is being used.
  2. An external database is out of the question.
  3. Speed is of utmost importance.
Unfortunately, by ruling out a database, you will not be able to achieve (1) and (2). Managing large volumes of data quickly and efficiently is what databases are for. You may not need to go to top shelf product like Oracle, DB/2 or Informix, but there are several open source database systems that do integrate with Perl. MySQL and Postgress are both used extensively.

Alternatively, you could try to "roll your own". You could try it - there is no way I would think about even attempting it.

Then again, it depends on just how much you mean by "lots".
