>> That solution can be correct in some situations. But I don't think that it is very interesting in the context of addresses.

I like that one, but I get scared by a thing we had in Atlanta where
there were 43 "Peachtree Street" designations in 1996 for the
Olympics; no idea what the count is today. You need a Civil
Engineering number as an identifier, which is what I called the
"street_code" in my skeleton DDL.
Parts of Atlanta are built on top of old parts of Atlanta -- Google
"Underground Atlanta"; the original streets are on to of the old
