Worked Solution & Example Answer:5.1.1 The electronic form below was designed to be used for online registration - NSC Information Technology - Question 5 - 2016 - Paper 2
Step 1
Critically comment on the layout of the components of the form, by indicating TWO ways in which the layout can be improved.
Answer
-
Grouping Related Information: The layout should group related information, such as personal details and exhibition information separately. This makes it easier for the user to understand and fill out the form without confusion.
-
Improve Navigation: The navigation can be improved by aligning the text boxes and buttons either underneath each other or arranging them in a single column layout to enhance readability and the natural flow of the form.
Step 2
Critically evaluate the components on the form that are used to obtain data from the user. Identify TWO poorly chosen components and suggest a more suitable component in EACH case. Motivate EACH suggestion.
Answer
-
Checkboxes for Gender Selection: Using checkboxes for gender is not optimal, as it allows users to select more than one option. A more suitable component would be radio buttons, as they restrict the user to one selection, which is appropriate for this scenario.
-
Table Selection: The table selection is currently a text input field, which is prone to errors. It could be better replaced with a dropdown list or combo box that contains a predefined list of options for the number of tables, ensuring valid and comparable entries.
Step 3
Using the above form, draw a UML (unified modelling language) diagram for the objStand object class.
Answer
class objStand {
- StallCode: string
- ExhibitorName: string
- PlugPoint: boolean
- NumTables: integer
- NumAssistants: integer
+ getStallCode(): string
+ setPlugPoint(pp: boolean)
}
