Database Schema Design

This handles the full lifecycle of database schema design, from initial entity modeling through migration scripts with rollback support. It covers normalization (1NF through 3NF), relationship patterns, and indexing strategies across PostgreSQL, MySQL, MongoDB, and SQLite. You get ERD diagrams, DDL files, and migration scripts with UP/DOWN paths, which is exactly what you need when refactoring a schema or starting fresh. The real value is in how it thinks through denormalization tradeoffs and generates complete artifacts instead of just advice. Solid choice if you're tired of hand-rolling migrations or second-guessing index placement.
