I am designing a data model for a local city page, more like requirements for it.

So 4 tables: Country, State, City, neighbourhood.

Real life relationships is: Country owns multiple State which owns multiple cities which ows multiple neighbourhoods.

In the data model: Do we link these with FK the same way or link each with each? Like in each table there will even be a Country ID, State ID, CityID and NeighbourhoodID so each connected with each? Other wise to reach neighbourhood from country we need to join 2 other tables in between?

There are more tables I need to maintain for IP addess of cities, latitude/longitude, etc.
