I think I've seen this type of question before. If I remember correctly, there are a couple key limitations to be aware of. I'll need to double-check the details, but I'm feeling reasonably confident about this one.
I've used full outer joins before, but I'm not as familiar with how they behave in a star join node. I'll need to make sure I understand the differences compared to other join types in that context.
Okay, let's see. I know full outer joins can be useful, but I'm not sure how they work in a star join specifically. I'll need to review the concepts around star joins and join types.
I think you're right, a full outer join includes all data from both tables. So, B) Only one column can be included in the join condition and D) It is restricted to one DIMENSION in a star join node are correct.
Nah, I'm pretty sure A and D are the right answers. You can't mix a full outer join with other join types in the same star join node, and it's limited to just one dimension.
