Chapter 09: Structured Data & Persistent Storage Quiz

Twenty-two questions. No tricks. If you've done the work in this chapter, you'll know these answers. If some questions stump you, that's not failure -- it's feedback. Check the source reference, revisit that lesson, and come back.

Scoring guidance:

• 20-22: strong operational readiness for chapter scope
• 16-19: good foundation, revisit weak outcome areas
• <=15: repeat core exercises before moving forward

Best practice: answer once without notes, then review misses and retake after targeted repair.

What This Quiz Measures

Missed a few? Good -- that means you know exactly what to revisit. Check the outcome IDs below to pinpoint which lesson to review.

• O1 misses (modeling and constraints): revisit Lessons 2 and 4.
• O2 misses (CRUD and session correctness): revisit Lessons 3 and 5.
• O3 misses (relationships and query reasoning): revisit Lesson 4.
• O4 misses (transaction safety): revisit Lesson 5.
• O5 misses (Neon operations and security): revisit Lesson 6.
• O6 misses (tool choice and verification): revisit Lesson 0, Lesson 7, and capstone policy sections.
