As merlyn says a RDBMS is probably the best solution, however if the task is simple and the data sorted you can possibly do it in perl much faster than with a RDBMS. What precisely do you want to do? More specifically is the data sorted (or could it be), unique/non unique ie given this input is there a neat way in perl to generate this output.
