First, Sorry for the Route/Road mismatch! In fact is it Road, i checked it before.

The structure:

Location ___|_______Road
___________ |____________________

IATA   PK    ----------->  ORIGIN            PK  +FK
spacee     ----------->  DESTINATION    PK + FK

So IATA is a String of an Location/Place and Road has a StartPoint (ORIGIN) and an EndPoint (DESTINATION). So Road has a double relation with Location.
The idea behind this structure, in Java, is to know from one Road, for example, which the Details of the Origin/Destination from type Location are without using SQL and just work with Java classes.

Best regards
