What is MVC, why and when do we use it?

MVC stands for Model View Controller. It is a software architecture system that basically structure that divide the tradional application structure into 3 part i.e Model, View and Controller. THe Model is responsible for database related functionalities such as schema, the View is reponsible for the front-end or the User Interface part of the application and finally the Controller is responsible for handling the logic and other computation, in the interest of separation of concerns from the HTML document itself and have a more modular aspect of programming.

We used scaffold to create the database structure for the various inputs of our project. The main controller of this project is named Infos pertaining to the main objective of this application that is to record user information such as First name, Last name, address and so forth.
Controller had the logic for creation, deletion and updation of various user data.
Views has various views such as for showing, updating and creating the various DB entries.

Controller: Create:

def create
@info = Info.new(info_params)

respond_to do |format|
  if @info.save
    format.html { redirect_to @info, notice: 'User Info was successfully created.' }
    format.json { render :show, status: :created, location: @info }
  else
    format.html { render :new }
    format.json { render json: @info.errors, status: :unprocessable_entity }
  end
end
end

Update:

def update
respond_to do |format|
  if @info.update(info_params)
    format.html { redirect_to @info, notice: 'Info was successfully updated.' }
    format.json { render :show, status: :ok, location: @info }
  else
    format.html { render :edit }
    format.json { render json: @info.errors, status: :unprocessable_entity }
  end
end
end

Deletion:

def destroy
@info.destroy
respond_to do |format|
  format.html { redirect_to infos_url, notice: 'Info was successfully deleted.' }
  format.json { head :no_content }
end
end

This is how we view the data in table format in views file.

<td><%= info.First_name %></td>
    <td><%= info.Last_name %></td>
    <td><%= info.email %></td>
    <td><%= info.Address %></td>
    <td><%= info.gender %></td>
    <td><%= info.Age %></td>
    <td><%= info.PhoneNumber %></td>

We learn how to use GIT properly to maintain a repo with more than and push changes to main repo. We also understood the flow of control of information in a MVC project after making the CRUD functionalities.
