I'm a little confused by this question. Is it asking about normalization or denormalization? I'll have to review my notes to make sure I understand the difference between those concepts.
Okay, I remember learning about this in class. The term for rejoining relations that were decomposed is B. Denormalization. I'm pretty sure that's the right answer.
Hmm, I'm not totally sure about this one. I know normalization is about breaking down tables, but I'm not confident which term describes the opposite process. I'll have to think this through more carefully.
I'm feeling a bit 'normalized' after reading these options. Maybe I should 'denormalize' my brain and go with B) Denormalization. It's the only one that makes sense to me.
D) Domain constraints? Really? That's more about defining the valid values for a column, not rejoining relations. I'm sticking with B) Denormalization.
