Welcome to your interview for the Software Engineer role at Sonsoft.

The question is on your right: Temporal Schema for History. Take a moment with it first.

Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen. You have three graded attempts to score 7/10 or better.

Only Submit answer is graded - discussion is free practice.

Problem

How would you design a database schema to support historical data tracking (temporal data) without severely degrading write performance for Sonsoft?
