mapping to our definition. Since we are using two tables we have to specify the
join conditions.
Click
Mapping—>Edit Join Conditions.

flightNo as a primary key, so they must match in
both tables. See Figure 9-15.

The complete definition is stored in passengerList.rmx, which is an abstract
representation of the mapping.
