Restful architecture and application integration

Restful architecture

modular hexagonal or layered architecture

Architecture can further be divided into a module or layered and each layer/module is responsible for one functionality, like layer MVC or module in node.js

Presentation — UI

A UI is only responsible to present view to the user like button, chart, table, and will communicate with backend via a protocol like HTTP

Business logic — the application’s business logic.

All business logic will be present in a Controller like we have in ruby on rails

Database access —

there can be a database access layer or models which will communicate to database or map data to the database like we have sequelize js/ mongoose in node.js
