Answer the following questions based on the above database:

1, Create a view named ATL_CHARTERS_V that includes the following For each charter of aircraft to Atlanta (STL), print the charter date, charter hours flown, and the corresponding customer last name, first name, area code, and phone number. Your answer should include both the SQL statement for view creating along with the contents of the view (you get the contents of the view by select * from ATL-CHARTERS_V).

Modify the MODEL table to add the following attribute: (Note: use ALTER TABLE and UPDATE commands for this question.)

Attribute name	Attribute Description	Attribute type
MOD_LIFT_ WEIGHT	Amount of weight each model can lift	Numeric

Once the attribute has been added, update the values of all rows as per following values:

Attribute values for MOD_LIFT_WEIGHT

10,000 for Mod_code = DC-90A

5,000 for Mod_code = MA23-250

20,000 for Mod_code = PA31-950

Create a trigger named trg_charter_hours that will automatically update the AIRCRAFT table after a new CHARTER row is added. Use the CHARTER tables CHAR_HOURS_FLOWN to update the AIRCRAFT tables AC_TTAF, AC_TTEL, and AC_TTER values.

The meaning for the AIRCRAFT table columns are as follows:

AC_TTAF: Total time on the air frame

AC_TTEL: Total time on the left engine (Also used to record single engine hours) AC_TTER: Total time on the right engine.

So in the trigger, you need to increase all of them with value of CHAR_HOURS_FLOWN
