What is the Sources and specific examples on hand course about?

Even strong data engineers find themselves second-guessing when senior stakeholders question schema decisions or pipeline patterns. Without clear precedent or documented tradeoffs, it's easy to lose ground in high-stakes design conversations, even when your instincts are correct.
