A customer can travel directly from city A to city B OR he can travel to from A to C and C-B.

In your assignment have to consider break journey options (A-C and C-B) and how did you handle this scenario?

HI,

Suppose I would like to add one more Domain class between Itinerary and Segment. I am not changing any cardinality between the existing domain classes as provided. So will this be a extending the BDM or changing the BDM?

Parag,

Question) A customer can travel directly from city A to city B OR he can travel to from A to C and C-B. In your assignment have to consider break journey options (A-C and C-B) and how did you handle this scenario?

Response) Yeah i did take care of the break flight. I think we cannot leave this out of design as there can always be a situation where flight route from A to X is not direct but is through other cities. Think of terms segment and leg and see how you can use them to come up with break flight? The same can be achieved with "n" # of designs.

Question) Suppose I would like to add one more Domain class between Itinerary and Segment. I am not changing any cardinality between the existing domain classes as provided. So will this be a extending the BDM or changing the BDM?

Response) Yep this will be extending the BDM.

Take care

Hi Vijay
I assume a segment means from one city to another city without stopover.
Am i right? what do you mean by leg? I think one flight can serve one segment and same flight or another flight can serve for another segment, is that called leg?

Thanks

Vijay,

Which version of UML you used, 1.1 or 2.0? Which Case tool you used for the exam?

Response) That is not the definition i used for segment. There is no 1 correct design, its all depends upon the assumptions you make and then be consistent.

Cheers

Vijay some more queries
1 .Did you use Cade's book as reference ? If yes what is customer in Cade's class diagram ? Similarly other classes which he has derived from domain model like LineItem, Return Request etc are not in sequence or component diagram. Are these persistent entities ?
2. you used simple MVC framwork that means you displayed the complete nine yards i.e. controller, BD etc ?

Vijay

These are my assumptions:

1. 1 equipment has 1 or more seats (association)
1..* 1
Seats------------------- Equipment
2. 1 Flight has 1 equipment (association)
1 1
Equipment ------------- Flight
3. 1 segment has 1 flight (association)
1 1
segments -------------- Flight
4. Itinerary has 1 or more segments (association)
1..* 1
segments --------------- Itinerary
5. 1 Customer has 0 or more Itineraries (Itinerary navigation association towards customer;
0..* 1
Itineary ---------> customer
6. Itinerary link with payment
1 1
Itineary --------> Payment
7. Customer has composite relationship with Profile as well as Mileage account
(1-1 relation ship)
8. Profile has composite relationship with Creditcard.
9. Payment is link with Mileage account as well as Creditcard.
Payment ------------> Mileage Account
payment ------------> Creditcard
Can you please suggest me, any navigation or aggregation or composite relation ships?

Thanks,
Vijay
