Perl's two primary data structures are the array and the hash. An array keeps its elements in a certain order; a hash is unordered but stores each of its values under a certain 'key', which may then be used to retrieve a given value. Arrays and hashes may both contain other arrays and hashes; in this case, they actually contain a reference to the array or hash.

If you want to see what these data structures look like, try use Data::Dumper; followed by print Dumper (\%hash), for instance.
