and the DepartAirportCode column in the Flight table
F. Create a foreign key constraint on the DepartAirportCode column in the Flight table to
reference the AirportCode column in the Airport table
G. Create a primary key constraint on the AirportCode column in the Airport table
H. Create a foreign key constraint on the AirportCode column in the Airport table to
reference the DepartAirportCode column in the Flight table
Answer: D, E, F, G
Explanation:
The answers will meet the design shown below:
1. Primary Keys
2. 1. Airport Table: AirportCode is unique enough.
2. Flight Table: Composite primary key for FlightNumber, FlightDate and
DepartAirportCode. (Flight Number itself may not be unique enough since they could be
reused)
3. Foreign Keys
4. 1. Airport Table: DepartAirportCode will reference AirportCode
2. Airport Table: ArriveAirportCode will reference AirportCode
1. CityOfOrigin is not necessary to uniquely identify records within the Airport Table.
2. FlightDate has to be part of the composite key within the Flight Table.
Having a cascade delete is a nice-to-have option on the database. It isn’t essential.
If you wish to delete an airport, you have 2 options :
o Delete all the related Flight records (programmatically) then delete the Airport record.
o Delete the Airport code and let the database delete all related flight children records.

QUESTION 3

application. What should you do?
A. Create a manual that can be downloaded from the Web site
B. Create a compiled help module and use context-sensitive help for all screen elements
C. Implement ToolTips to provide information about all screen elements
D. Use the ALT attribute to provide a short textual description for all images and audio
files
Answer: C
Explanation:
C. This is the most suitable answer
Note:
Providing online user assistance
Even the best user interface design and input validation procedures cannot ensure
that your users will be able to know what to do and when to do it. To avoid
personally training and supporting every user through their individual learning
curves, you need to make some form of online user assistance in a format they are
able, willing, and ready to call up. The most common ways to do this are through
the use of status bars, tooltips, and application help files.
Incorrect
Answer:
A. This is an offline help method.
B. This is suited for Windows Applications instead of Web Applications.
D. This is normally used for people with disabilities.
