hi all,
from the requirement of FBN, i found that no system for flight data
or seat data is described. so i'm very confused. how can the system
get the data about how many flights are there from A city to B city,
and how many seats are there in one flight? what can the client do
when they want to add some information about flights in the future?
or delete some flights when they are canceled?
thanks in advance.

Patrick,
The BDM includes entities 'Flight' and 'Seat'. I think you have to make an assumption that they contain all the data you require.

Hi Ray,
so may I look it as a subsystem of flight?
or i should build some ejbs to maintain those datas
and make it part of my system as the customer module?

Thats the choice u need to make. There are many ways for the solution.
U need to explain your decision and how it meets the requirement.
If u go the EJB route peformance and scalability factors. Other times u may want to use the Fast lane reader for better performance but outdated data.
These are just some of the issues u may want to address before deciding which design works for u.

U may also need to document all your assumptions
