MongoDB entity relationship graph mapping user-centric data flows across smart kitchen appliances, recipe management, and e-commerce domains. Users connect to sessions, machines, and transactional entities like orders and grocery lists, while recipes form a rich subgraph linking ingredients, brands, and cooking templates. This schema demonstrates denormalization patterns for read-heavy workloads in connected device ecosystems with complex meal planning workflows. Fork this diagram on Diagrams.so to adapt the entity relationships for your own IoT or food-tech data model. The recipe_proxy intermediary pattern enables staging and versioning without disrupting production recipe data.
