Suppose that a new residential neighborhood has opened in the city and it cannot be placed
in any other district. Then the system must have a new district added to the sytem and pretend
that the new district will be called "Happy Valley"
Assuming that the Add button has been pressed then the system will automatically generate
a district number but the user will have to enter a district name in the field labeled
district name.
Click on the district name field and enter Happy Valley
If the user desires they can enter the population of the district.
Enter 1024 in the field labeled population.
You have just completed the addition of a district to the system. Also contain within the District interface are two other fields. The Household field stores the number of households being serviced by Northam and the Retail field stores the number of retail outlets being serviced by Northam. These fields are just form information purposes and cannot be altered. The system automatically generates the values that appear in these fields.
