A framework is a software toolkit with prewritten code libraries and datas organized in structures , which helps you in developing applications. Ruby on rails framework is based on MVC architecture. So what the heck is a MVC architecture. To put it in a simple way. MVC pattern is a way to deveop an applcation in a organized and secure way.
View: View is the web UI of the application where the user submits the requests and view contents of the application.
Controller: Controller is the integral part of the MVC architecture. Controller handles the incoming user requests from the UI and process it according to the needs. If the request is to update or delete any data from the database , the controller will process the request accordingly by sending appropriate requests to the database.
If we take the traditional web applications, the view and the controller are bundled together. when a user creates a request for some data, the code that is bundled with the UI will process the request and connect to the database based on user needs. But in MVC the UI, business logic and data are seperated.
