This week we've looked at the difference between traditional transactional databases and data warehouses. Though both can be represented using relational structures, there are significant differences in the normalization between the two. For this discussion, give one real-world example of where you might want to denormalize a transactional database for a particular data question. What problem are you trying to solve, what question are you trying to answer and why does the alternate data format help more efficiently produce the answer you're looking for?
