FBN client side classes (Itinerary, Segment, Flight)

Hi there,

With the FBN assignment, the domain model shows Itinerary, Segment and Flight.

It seems that there need to be something equivalent on Client side as well, because we would not want to send clients a chain of objects when they are only interested in some properties of these objects.

I am thinking there has to be a FlightSpecification class since client class does not need to know that Flight has links to Equipments, etc., in other words I do not think we should expose Flight's server side functionality to client.

The question next is do I need to create client side classes for Segment as well? If not, where do I place info. regarding Itinerary and Segment for clients? There has to be a class to hold such info. Since Segment has links to server side Flight, I wouldnot want to send Segment to client, either.

What does everyone else think?

As an architect, you should be familiar with the J2EE design patterns (particularly with the VO/DTO pattern)
