Name the idea, why it exists, then one short example.
End with when you use it and one common pitfall.
STEPS — What happens step by step?
Before you speak the answer, walk the interviewer through these steps:
- 1Owned types store related
value objects in the same table or dependent table without their own identity key for domain use.
- 2Why it exists
Addresses are a common example.
- 3Identity still exists under

- 4Give an example
One tiny concrete case you can say aloud.
- 5Common mistake
What juniors usually get wrong.
- 6Close
When you pick this over the alternative.

Key takeaway
Owned types store related value objects in the same table or dependent table without their own identity key for domain use. Addresses are a common example.
