Even in financial / tax software it is possible to create an abstraction in which you can safely write English code and move all specific terms into some i18n module. Of course if you are not clever enough to do that it's not that bad to use /required/ language, but in this case we talk about strictly technical tool for database modeling, so no excuses - it definitely needs to be translated in order to be accessible for other GitHubbers.
