Hibernate understands mapping a collection into 4 parts
  1. The key - the foreign-key defining the association to the owner
  2. The element - for Maps this is analogous to the value
  3. The index - the List/array index or Map key
  4. The collection-id - this is only relevant for id-bag mappings
