Hi Perl Monks, I am here again for your help.I have 2 complex data structures that need to be compared with each other.Each and every key/value pair needs to be compared. I made use of the Data::Compare module, but the problem I am unable to resolve is how do I sort these data structures before comparison? Please help me with this. Thanks a lot in advance. Here is my code: 
#!/usr/bin/perl

use strict;
use warnings;
use Data::Compare;
use Data::Dumper;

my @array1 = [
{'platformid' => '22','da' => 'A.9','os' => 'hp-ux-11.31','host' => '2
+060','cc' => 'A.9','ma' => 'A.9','size' => [{'objecttype' => 'FILESYS
+TEM','totalsize' => '3628129 KB','application' => '/depot','hostname'
+ => 'iwf1112060'}],'objecttype' => '2'},
{'platformid' => '100','da' => 'A.9','os' => 'microsoft amd64 wNT-6.1-
+S','ma' => 'A.9','cc' => 'A.9','size' => [{'objecttype' => 'OB2BAR','
+totalsize' => '230986 KB','application' => 'IDB','hostname' => '5096'
+},{'objecttype' => 'WINFS','totalsize' => '1262152 KB','application' 
+=> 'R: [New Volume]','hostname' => '5096'},{'objecttype' => 'WINFS','
+totalsize' => '574463 KB','application' => 'C:','hostname' => '5096'}
+],'objecttype' => '6','host' => '5096'}
];

my @array2 = [
{'platformid' => '100','da' => 'A.9','os' => 'microsoft amd64 wNT-6.1-
+S','ma' => 'A.9','cc' => 'A.9','size' => [{'objecttype' => 'OB2BAR','
+totalsize' => '230986 KB','application' => 'IDB','hostname' => '5096'
+},{'objecttype' => 'WINFS','totalsize' => '1262152 KB','application' 
+=> 'R: [New Volume]','hostname' => '5096'},{'objecttype' => 'WINFS','
+totalsize' => '574463 KB','application' => 'C:','hostname' => '5096'}
+],'objecttype' => '6','host' => '5096'},
{'platformid' => '22','da' => 'A.9','os' => 'hp-ux-11.31','host' => '2
+060','cc' => 'A.9','ma' => 'A.9','size' => [{'objecttype' => 'FILESYS
+TEM','totalsize' => '3628129 KB','application' => '/depot','hostname'
+ => '2060'}],'objecttype' => '2'}
];

my @array3 = sort {$a->{platformid} cmp $b->{platformid} or $a->{da} c
+mp $b->{da} or $a->{ma} cmp $b->{ma} or $a->{os} cmp $b->{os} or $a->
+{cc} cmp $b->{cc} or $a->{objecttype} cmp $b->{objecttype} or $a->{ho
+st} cmp $b->{host} or $a->{size} cmp $b->{size}} @array1;

my @array4 =  sort {$a->{platformid} cmp $b->{platformid} or $a->{da} 
+cmp $b->{da} or $a->{ma} cmp $b->{ma} or $a->{os} cmp $b->{os} or $a-
+>{cc} cmp $b->{cc} or $a->{objecttype} cmp $b->{objecttype} or $a->{h
+ost} cmp $b->{host} or $a->{size} cmp $b->{size}} @array2;

my $array1ref = \@array3;
my $array2ref = \@array4;

# print Dumper $array1ref;
# print Dumper $array2ref;
my $rc = Compare($array1ref,$array2ref);
if($rc == 1)
{
    print "Data structures are equal";
}
else
{
    print "Data structures are not equal";
}
