Covers the core mental shift of modeling around access patterns rather than normalization, three structural patterns (Attribute, Bucket, Computed), the embed vs. reference decision with a practical checklist, and the Subset/Hybrid pattern. The aggregation pipeline section walks through $match, $group, $lookup, $unwind, $project, $addFields, and $facet with real-world scenarios including a monthly revenue cohort analysis. Also addresses performance considerations like using explain(), compound indexes, avoiding $where, and common pitfalls like unbounded embedded arrays and overusing $lookup in hot paths. ## Full article daily.dev links to this article rather than hosting it.
