Speaking as someone whose primary role is application designer, I would say that data design is *more* important than application design. Data design is the foundation that applications are written on.

These are critical. Denormalization leads directly to data corruption, as well as application bugs.

If you can't modify the design, you can't modify the design.

I have found that it's pretty common to run in to people who have a rigid idea of how to do things. They can't be argued with because their methodology is a priori, and not based on any particular theory or understanding. If you present a good case for changing a process and someone doesn't agree, but presents technical reasons against your idea, then you don't have one of those; you have someone whose experience is different and possibly greater than yours. If the person responds with assertions to the contrary absent any technical reasons, you have the rigid guy.
Good luck.
