What is sequelize?
Sequelize is an Object-Relational Mapping (ORM) library for Node.js that lets you interact with relational databases like PostgreSQL, MySQL, SQLite, and SQL Server using JavaScript objects instead of writing raw SQL queries. Developers use it to simplify database operations, manage complex relationships between data, and handle transactions while reducing boilerplate code. It supports advanced features like eager loading, lazy loading, and read replication across multiple database systems.
