Data Modelling How Swiggy's Data Model Is Built

From entities and keys to a normalised, production-shaped schema for a real food-delivery system.

Everyone writes SQL. Very few can design the tables behind it. In three hours we build Swiggy's data model live: entities, attributes, keys and cardinality, an ERD sketched before any DDL is written, normalization from 1NF to 3NF — and when denormalizing is the right call — finishing with customers, orders, order_items and restaurants wired end to end. You leave with a schema you can defend in an interview, and a repeatable way to model any system.
