what is a street name?

[Max Voskob <max.voskob@paradise.net.nz>]

Hi all,

Can anyone explain to me what's the benefit of splitting street names into multiple parts, such as:
- pre-direction (NORTH Baker st)
- leading type (AVENUE of John Banks)
- name (North BAKER st)
- trailing type (North Baker STREET)
- post-direction (Baker st NORTH)

This looks very normalised in the schema, but for what purpose?

Can anyone use those elements separately one from the other?
Any examples?

Cheers,
Max
