Database Normalization

Question

I\'m new to database design and I have been reading quite a bit about normalization. If I had three tables: Accommodation, Train Stations and Airports. Would I have address

Answer 1

This isn't really what I understand by normalisation. You don't seem to be talking about removing redundancy, just how to partition the storage or data model. I'm assuming that the example of addresses for Accommodation, Train Stations and Airports will all be disjoint?

As far as I know it would only be normalisation if you started thinking along the lines. Postcode is functionally dependent upon street address so should be factored out into its own table.

In which case this could be ever desirable or undesirable dependent upon context. Perhaps desirable if you administer the records and can ensure correctness, and less desirable if users can update their own records.
