I'm a little confused by this question. I'm not sure if I should use the existing tests or create new ones. Maybe I'll go with option D and just focus on testing the existing code.
Ah, this is a good one. I'd say option C is the way to go. Creating test data based on the use case is a solid approach to thoroughly test the code in the development/testing environment.
Hmm, this seems like a pretty straightforward question. I think I'll go with option C - create test data based on the use case to test both existing and new tests.
I'm a bit unsure about this one. I'm thinking either option C or D, but I'm not totally confident. Maybe I'll just go with C since it seems to cover more bases.
Ugh, I'm a bit confused on the details of the relational model. I'll have to review my notes to make sure I understand the key characteristics before selecting the incorrect statement.
Hmm, I'm a little unsure about this one. I know the concepts of backward chaining, contingency-shaped behavior, and rule-governed behavior, but I'm not totally confident in applying them to this specific scenario. I'll have to think it through carefully.
This looks pretty straightforward. I'd probably go with option C - using the Supplier/Item Relationships to update the prices based on the currency and exchange rate. Seems like the most logical way to handle it.
