Normal Forms as the basis for specifying mappings
- If we consider XML representations of data conceived of at the
Entity/Relationship/Collection level
- A number of design patterns or ‘normal forms’ exist:
- Alternating or striped (elements encode entities and
relations, alternately)
- Elements encode relations (and entities are covert)
- Elements encode entities (and relations are covert)
- Particular XML applications can be understood as variations on this theme
