Perl has a built-in Storable module that you can use to store complex data structures in some sort of storage so that you can recover later.

This example is from the Storable man page with a few comments added by me:

Code:
use Storable;
# %table is the hash to be stored in file 'file'
store \%table, 'file';
# Then recover the hash from file (you need to de-reference it to get its content)
$hashref = retrieve('file');

Storable - perldoc.perl.org

NAME
DBIx::Class::Serialize::Storable - hooks for Storable nfreeze/thaw DEPRECATION NOTE
This component is now DEPRECATED. It has not been providing any useful functionality for quite a while, and in fact destroys prefetched results in its current implementation. Do not use! SYNOPSIS
# in a table class definition __PACKAGE__->load_components(qw/Serialize::Storable/); # meanwhile, in a nearby piece of code my $cd = $schema->resultset('CD')->find(12); # if the cache uses Storable, this will work automatically $cache->set($cd->ID, $cd); DESCRIPTION
This component adds hooks for Storable so that result objects can be serialized. It assumes that your result object class ("result_class") is the same as your table class, which is the normal situation. HOOKS
The following hooks are defined for Storable - see the documentation for "Hooks" in Storable for detailed information on these hooks. STORABLE_freeze The serializing hook, called on the object during serialization. It can be inherited, or defined in the class itself, like any other method. STORABLE_thaw The deserializing hook called on the object during deserialization. AUTHOR AND CONTRIBUTORS
