If you merely want to *store* data on disk, rather than use a database, you could simply use Data::Dumper to dump a data structure to a file. Then, you want to build a 'hash of arrays' to store multiple key values, like this: 
use Data::Dumper;

my %HoA = ();

# crude code to illustrate:
$HoA{'key1'} = ['1', '2', '3'];
$HoA{'key2'} = ['a', 'b'];
# etc.

# Dump it     
open($OUTFILE, '>', 'data.dmp');
$Data::Dumper::Indent = 3;
$Data::Dumper::Purity = 1;

printf $OUTFILE Dumper(\%HoA);
close($OUTFILE);

Then, later you can read it back in, and eval it to access the data.
