I have always thought that sparse arrays was just another term for a hash.

No. Hashes are unordered collections. You can impose an order on them by requiring ordered keys and then use a hash to implement a sparse array. Additional information, such as a normal dense array containing the sorted hash keys, are needed in order to allow iteration though.
