Sequelize works on the principle of mapping database entries to JS objects and vice versa.

This is because JS objects are very well documented and JavaScript itself was modeled to deal with array structures much better than with SQL tables.

This enables a developer to manipulate a the data much easier in Node.js server-side environments, by using JavaScript instead of SQL commands.

Sequelize is quite advanced, supporting most operations supported by SQL engines, allowing an in-depth manipulation and processing of SQL data, just what developers have wanted from their ORMs.

Sequalize has been tested and seamlessly works with Express and Heroku-powered apps.

Currently supported databases:

MySQL

MSSQL

SQLite

PostgreSQL

MariaDB
