Model View Controller - review

Model-View-Controller Review

http://www.brandeis.edu/index.html
  • Reminder:
    • Basic Client <-> Server structure
    • MVC is a general pattern
    • Here we are applying it to a web (http) server
  • The Models: contains the application ‘state’
    • Think of it as what you want preserved if your app (i.e. the server in our case) has to be restarted
    • Think of your user’s reasonable expectations
    • Discussion
  • The Controllers: master control switch
    • Sees requests from the outside world
    • Asks the models for data, sometimes updates the data
    • Asks the views for new pages or results
    • Responds to the request
    • (Note: this parallels the HTTP protocol exactly!)
  • The Views
    • Use data (given by the controller)
    • To create and assemble responses to be sent
    • Responses are html, but may be other formats too
