Assuming that AddressDB::People is a DBIx::Class-based model, then

my $people = $c->model('AddressDB::People')

will get you a DBIx::Class::ResultSet object, which is an object. You  
can then use that object to iterate over the resultset or chain  
another search on it.

my @people = $c->model('AddressDB::People')

will get you an array of row objects, which are the values returned by  
iterating over the resultset. It's the equivalent of $c- 
 >model('AddressBookDB::People')->all();

Catalyst just provides a thin wrapper around the model, so this  
doesn't really have anything to do with Catalyst and is more the  
behaviour of DBIx::Class.
