Naming Convention for Israel street names

I mean:
“Rehov” (or “Sdera”, or "Derech, for that matter) is not part of the name of the way.
You can see it as some feature (or “type”) of the way.

That means, that in a normalized DB, we will have a table of all way name features (rehov, derech, simta, etc.) and in the ways table, there will be a column that points to that table.
