As the application support person I want to be on the latest version of database because it is more reliable / more secure / whatever.
You could even phrase refactoring like that:
As the application developer I want all the data classes in one module so that I can add new fields to the app very quickly.
- Who benefits
- What you want to do
- What the benefit is
Ideally you don't want all the stories to have 1 be developers, but a few make sense (sharpening your ax instead of cutting down trees and all that).
