I thought data tables could also store raw data?

B is more structured, so it can't be unaltered.

Definitely A, data lakes hold raw data.

Data factory sounds like it processes data, so I doubt that's the answer. I’m leaning towards data lake as well.

I'm a bit confused; I thought data tables could also hold unaltered data, but maybe that's not the case in this context?

I remember practicing a question like this, and I think data warehouses usually transform data, so that rules them out.

I think a data lake is the right answer since it stores raw, unaltered data, but I'm not completely sure.

I'm leaning towards the data lake as the answer, but I want to double-check my understanding of the differences between the data repositories.

I think the data lake is the best choice for storing unaltered data. The question is asking about the repository, not the processing or transformation of the data.

Data lake sounds like the right answer here. It's designed to store raw, unprocessed data, unlike a data warehouse which stores transformed data.

Hmm, I'm a bit confused between the data lake and data warehouse. I'll have to think this through carefully.

Data factory? What is this, some kind of data assembly line? I want my data to be free-range, not mass-produced!

I prefer my data to be free-range too, but sometimes a data factory is necessary for certain processes.

Data factory does sound like a data assembly line, but it's actually a repository that stores unaltered data.

User 1: Data factory is not a data assembly line, it's a repository for processed data.

Data table? Isn't that just a fancy way of saying 'spreadsheet'? I'm not looking to organize my data, I want it to be a wild, untamed beast!

Hmm, a data warehouse? Isn't that where data goes to get all cozy and structured? I'm looking for something a little more 'au naturel', if you know what I mean.
