Hello,
i'm working on SCEA part 2 and i'm getting really confused.
I can't understand how the itinerary is created. I try to be clearer.
If i want to move from Rome to New York my itinerary would be (for example):
Rome -> London (Segment 1)
London -> New York (Segment 2)
How the system can know that i've to stop in london if i depart from rome to go to new york.
Should i investigate how the system work to find this 2 segments? Or i should simply assume that there's a component that gives to me the segments connecting two cities.
In other words, the connections n the time table is stored somewhere on the DB n i should access it or it is out of the exam this part?
Pls Help me!!!
Thx
F.

Now, if i look at the BDM i notice there's just one to one relation between Segment and Flight, but at the same time, in the real life, there can be more than one flight for each segment.

1. The assignment instructions clearly mentions that one need not have to explicitly specify the method signatures.

2. Each segment has one and only one flight

Each flight has many seats because a customer can book any number of seats (for himself and his family) on a flight.
