The best UI for a records system is the one nobody notices. Staff learn it once, use it for years, and never think about it, that's the goal, not a redesign every cycle.
Boring UI means familiar patterns: tables that look like tables, buttons that look like buttons, navigation where people expect it. Every novel pattern is a training cost someone else pays.
The systems that age well aren't the ones that won design awards, they're the ones a new hire can use on day one without a manual.
