README

If you are not willing to setup the project in your local system then you can go to the following link given at the end of this file to run the application on the web. This application is hosted on heroku (initially it will take time because hosted on a free dyno).

This file will tell you how to setup your system and run this test.

List of Dependencies:

Active Record

As we know that rails uses MVC architecture where M stands for Models, V stands for Views, C stands for Controllers. Models are responsible to connect the application with the database (a layer which runs between the database and business logic). Active Record is the ORM in which tables are mapped to classes, objects are mapped to rows/records, and columns are mapped to attributes. Business logics are to be written in models to make light weight controllers.

click on Active Record button

A dialog box will appear.

Click on Seven Segment button
