I think Nu is right, observation is about watching or looking at something carefully.

But isn't sampling the process of selecting a representative amount of data from a main repository?

That's true, Aja. Delta load is about updating only the changes since the last load.

I believe Delta load is used for incremental updates, not representative sampling.

I see your point, Lashawn. But sampling is specifically about selecting a subset for analysis.

But could it also be A) Observation? I mean, observing data can also give insights.

I agree with Nichelle. Sampling is taking a subset of data to represent the whole.

I don't know, I'm leaning more towards option B, the delta load. That seems like a more efficient way to work with large datasets.

Hmm, I was thinking it might be a delta load, where we only load the changes or new data from the main repo. But I guess sampling makes more sense in this context.

Yeah, I think you're on the right track. Sampling is a common technique in data analysis to get a good understanding of the larger dataset without having to process everything.

I'm pretty sure this is asking about data sampling. We use a representative sample of data from the main repository instead of the entire dataset, right?
