In MyApp.pm:
# Start the application
__PACKAGE__->setup();
mymethod();
sub mymethod {
...
}
But that's probably not what you're looking for...

Create a model for it.
$ script/myapp_create.pl model MyData
Then create the data structure in Model/MyData.pm:
package MyApp::Model::MyData;
use Moose;
extends 'Catalyst::Model';
has 'mydata' => ( is=>'rw', isa=>'HashRef', default=>sub{{}} );
no Moose;
sub BUILD {
my $self=shift;
my $data = MyApp->model('DB::Table')->search(...)->first; # I rather
avoid storing dbic resultsets in memory for a long time.
$self->mydata({ foo=> $data } ); }
}
Then call it from any controller:
sub foo : Local {
my $c=pop;
$c->stash->{foome} = $c->model('MyData')->mydata->{foo};
}

If don't have $c defined, you can use MyApp->model() most of the time.
