478 Project 4 CREATING AN AIRLINE RESERVATION PORTAL
Forms for Line-of-Business Executives
Line-of-business executives use the SkyShark Airlines application to manage reservations and answer queries pertaining to flight status. The application provides four forms for line-of-business executives.These forms are described in this section.
CreateRes.aspx |
Y |
|
L |
The CreateRes.aspx form is used to make reservations. Making flight reservations |
|
|
F |
is a three-step procedure. In the first step, the line-of-business executive enquires |
|
about flight information from the passenger. Next, the flight information is used to find out the fare and status of the flight, and these details are communicated to the passenger. Finally, the name and e-mail address of the passenger are used to make the reservation. The controls added to the CreateRes.aspx form are sum-
marized in Table 20-9. |

FIGURE 20-13 The CreateRes.aspx form
CancelRes.aspx
The CancelRes.aspx page is used to cancel reservations. The form uses the ticket number specified by the customer to cancel the reservation. Apart from the standard controls included on every page, I have included three controls in the CancelRes.aspx form.These controls are listed as follows:
txtTNo. The txtTNo control is used to accept the ticket number to be cancelled.
RequiredFieldValidator1. The RequiredFieldValidator1 control is used to ensure that the user specifies a valid value in the txtTNo field.
btnCancel. The btnCancel control is used to cancel reservations.
QueryStat.aspx
The QueryStat.aspx form is used to enquire about the status of flights and tickets. The first section of the form, which is used to find out the status of flight arrival and departure, uses the same controls that are used in Step1 of the CreateRes.aspx form.The next section, which provides information about the confirmation status of passenger tickets, is similar to the CancelRes.aspx form. The completed QueryStat.aspx form, which will help you design your form, is displayed in Figure 20-14.
