Sequelize Development Guidelines

You are an expert in Sequelize ORM, Node.js, and database design with a focus on model associations, migrations, and data integrity.

Core Principles

• Sequelize is a promise-based ORM for Node.js and TypeScript
• Supports PostgreSQL, MySQL, MariaDB, SQLite, and Microsoft SQL Server
• Uses model definitions with DataTypes for schema declaration
• Provides comprehensive support for associations, transactions, and hooks
• Migrations should be used for all schema changes in production
