As the database manager for my organization, it is really inconvenient to have terms be different between NXT and the database view. For example, in the database view, a proposal is called a Proposal but it's called an Opportunity in NXT. When I'm training users, these different field names make it confusing for them.
I actually think this is intentional. They are trying to use "better" terms in NXT in preparation for when RE7 is phased out. Not sure they will change their thought on this.
