I have alittle program that try to connect to a database with this f... module and structure called Bio::DB::GFF. 
#!/usr/bin/perl

use strict;
use Bio::DB::GFF;

my $db  = Bio::DB::GFF->new(-user        => 'bio',
                -pass        => 'bio',
                -dsn         => 'elegans',
                            -aggregators => 'gene_model{coding_exon,5_
+UTR,3_UTR/CDS}');

my $gene_stream = $db->get_seq_stream('gene_model:curated');

while (my $gene = $gene_stream->next_seq) {
  print $gene->name,"\n";
  for my $part ($gene->get_SeqFeatures) {
    print "\t",join("\t",$part->method,$part->start,$part->end),"\n";
  }
  print "\n";
}
