Wait, reasonless check? Is that even a real thing?

Cyclic redundancy check? Really? That seems off.

I think edit check could work too, but not as effective.

Sequence check is the way to go for duplicates.

I don't recall much about reasonless checks, but they sound like they wouldn't be effective for this scenario.

I feel like cyclic redundancy checks are more about error detection in data transmission, not really for preventing duplicates.

I'm not entirely sure, but I remember practicing with edit checks for data validation. Would that help with duplicates?

I think a sequence check might be the best option since it can help ensure that each voucher is unique and in order.

The calendar delivery deadline and the need for a recruitment campaign within 12 months seem like the most relevant timescale considerations here. I'll go with those.

I remember something similar in our practice questions, and I think regressive applies when lower incomes pay a higher percentage.

I think an entity is a single relation... or maybe it's the thing we store info about? Ugh, I wish I had focused more on this topic!

Hmm, I'm a bit confused by the different code snippets. I'll need to carefully analyze each one.
