, Task 1
Task 1a) Requirements of the program
In this task I will be talking about the requirements and objectives of this program that I will build.
This task will outline how my program will function.
The program is so that Arima Railways can have a computer application to reduce the need for train
and tram tickets at railway stations and tram stops. This is so they don’t waste money on printing
extra paper and so they are able to profit and so lots of people don’t queue at the train and tram
stations before their journey. This way people can just book at home and just go on the train when
they need to go. Moreover, Arima Railways have a staff shortage as they are required to balance
their accounts to avoid administration. With this application it will be a blessing for the company.
The objectives of this application are that:
The Graphic User Interface (GUI) should be user-friendly so that users find it easy to use,
easy to understand without any difficulty and that users can see the screen clearly.
One way we could it user-friendly by having a help button which when pressed will lead you
to a webpage which will give the users help if they struggle to understand the application.
The users of this application should be able to pick their starting place and destination place
of their journey.
The user should be able to pick how many tickets they want to buy and what type of tickets
they want to purchase e.g. student, adult, etc.
The program should have an option for the user to be able to choose what they want to pay
with e.g. MasterCard, Visa, etc. Be able to see how much they need to pay.
The users should be able to print the receipt of the tickets.
Inputs and Outputs and Processes
This is the input, outputs and processes table (see table 1 below) which shows what I inputted into
the program, how it was calculated and what will be outputted in the program.
Table 1: Input Output Processes Table
Inputs Processes Output
Book 2 adult tickets and 2*30 = £60 for Adult £100
1 child tickets to travel 1*20 = £20 for Child 2 Adults
on a single economy +£20 for Economy 1 Child
