Sequelize is a popular Node.js ORM supporting PostgreSQL MySQL SQLite MariaDB and MSSQL providing a promise-based API for database operations without writing raw SQL. The library handles model definition associations validations and migrations making it straightforward to work with relational databases in JavaScript applications. Sequelize supports eager and lazy loading of associations along with hooks for extending behavior. The framework is widely used in production applications and has extensive documentation and community support.
