Quick Reference
MongoDB: Embed for 1:few relationships accessed together. Reference for 1:many, shared data, large/unbounded arrays. Avoid arrays >100 items. Index query patterns, not all fields. Use explain() to verify index usage. Aggregation $lookup is expensive - prefer embedding. Shard key choice is critical.
