Association seems too loose for this kind of relationship.

Generalization doesn't make sense in this context.

Wait, could it be aggregation instead? Not so sure.

Totally agree, composition fits perfectly here!

It's definitely a composition relationship.

This reminds me of a practice question where we had to differentiate between aggregation and composition. I think this one leans more towards composition.

I'm a bit unsure, but I think aggregation could also fit because the invoice can exist without the items if it's just a placeholder.

I remember we discussed that composition implies a strong lifecycle dependency, so I think it might be composition since the invoice items can't exist without the invoice.

I feel like association could be a possibility too, but it seems too loose for this scenario. I’m leaning towards composition as well.

Okay, let me think this through. The key details are that this is the phase after powering on the EFI system and before the PEI. That sounds like the Pre-EFI initialization phase to me, so I'll go with A.

Okay, I've got this. The key is to link the Customers data extension to the data model using the Customer ID, and then connect the Orders data extension to the Customers data extension using a One-to-Many relationship. That should give me the data I need to set up the Journey.

I remember something about bursts of activity in our study sessions. That might relate to performance spikes during testing, but I can't recall if it's the right option.

Okay, I've got a strategy for this. I'll think about which industries rely more on borrowing and financing, as those would likely be hit harder by rate hikes. Public utilities and brokers seem like good options.

Okay, I think I've got this. The key is that the bank accepted the money on Monday and didn't purchase the securities by the end of Tuesday. Based on that, I believe the correct answer is B - the bank must purchase the securities before the close of business on Wednesday.
