Nosql Database Design

This handles the design patterns you need when you're building schemas for MongoDB or DynamoDB instead of relational databases. It covers the classic embedding versus referencing decisions, how to denormalize data without shooting yourself in the foot, and query optimization for document stores. You get reference guides on document structure, MongoDB indexing, schema validation, DynamoDB table design with GSIs, and item operations. The quick start shows a basic user document with embedded address and orders array, which is the bread and butter pattern. Honest take: NoSQL gives you flexibility but you can still make a mess of it. The structured guidance here keeps you from reinventing wheels or falling into common traps around data modeling.
