SharePoint Cloud hosted Apps Girish

SharePoint Development Challenges Code runs in full trust code Developers need a dedicated SharePoint server

SharePoint Apps Apps cannot run SharePoint server side API code instead use REST/CSOM App Solution does not live on SharePoint instead Executes at the client context(Browser) or at a different server(IIS server or Azure) and hence isolated from SharePoint Apps are given permissions to SharePoint using OAuth Developers need not Know SharePoint API and can use REST and OAuth(Industry based) for communication with SharePoint

Why MVC Enables the full control over the rendered HTML. Enables Test Driven Development(TDD) Following the design of stateless nature of the web.

How MVC Works The Model is the part of the application that handles the logic for the application data. Often model objects retrieve data (and store data) from a database. The View is the parts of the application that handles the display of the data. Most often the views are created from the model data. The Controller is the part of the application that handles user interaction. Typically controllers read data from a view, control user input, and send input data to the model.

How MVC Works User enters the URL Route handler parser the URL and decides on which controller to run Controller contain actions methods which act on the model Controller renders the result to view engine

View Two ways of data communication View bag(loosely coupled) View model(tightly coupled)
