What is MVC ?

• MVC stands for Model ( Data ) + View ( UI ) + Controller ( Brain )
• The core concept is to separate the business logic, user interface and data model from each other.
• Model extracts data from a database like cloud, local storage, API's
• View represents the UI of app, it shows the data model and takes inputs from the users.
• Controller consist of business logics, control and decide what will be displayed to user.
• MVC helps to make work easy, structured and organized.
• So if something is changed in one part of the project, it will not affect other parts of the project.
• The user interacts with view on which data is displayed and provide input with controller through view
• Controller is like brain it manipulates the data for user or take data from model to work.
• And after work is completed again it is provided back to view which shows desired data to users.

Can we use Multiple web.config file ? : Yes

• We have one main configuration file that is Web.Config
• Then we have two more configuration files App.Config and Database.Config
• In App.Config we define all the application level settings like Protocols, Requests and Responses
• In Database.Config we define all the database level settings like Data Source and Passwords

<appSettings configSource="app.config">
</appSettings>
<connectionStrings configSource="database.config">
</connectionStrings>
