Sequelize
Promise-based ORM we use to support established Node services across SQL databases.
About Sequelize
Sequelize is a promise-based ORM (Object-Relational Mapper) for Node.js that supports PostgreSQL, MySQL, MariaDB, SQLite, and MSSQL. It provides an abstraction layer to interact with relational databases using JavaScript or TypeScript. Sequelize includes features like model relationships, migrations, eager/lazy loading, and raw query support. Its powerful query builder and flexible model definitions simplify database management in large-scale apps.
How We Use Sequelize
At ITBCO Solutions, we use Sequelize for building scalable backend APIs where relational data modeling is needed. It allows us to keep our business logic clean and structured while using native SQL features when necessary. We use Sequelize migrations and seeders to manage schema evolution across environments and CI pipelines. Its strong support for model associations helps us build normalized data schemas with complex relationships.
