2024 VCE paper; section C; Q11 (2 marks)
Vanja suggests that customers could be provided with a discount code, such as ‘FREECAKE’, that they could use to receive free items with their purchases once enough points have been earned. The code should be made invalid after it has been used. Data integrity would be diminished in terms of correctness if the code could be used more than once.
Identify a different characteristic of data integrity, and describe how a discount code that could be used more than once could impact on this characteristic.
Suggested
As correctness is already defined in the question, you can discuss authenticity, correctness, reasonableness, relevance, or timeliness. For this question, authenticity should be the focus.
Repeated illegitimate usage of the discount code is fraudulent/unauthorized making the rewards system unable to authenticate rewards, hence rendering it unreliable and inauthentic, negatively impacting the data’s integrity.
