The MVC PatternModel-View-Controller

4

Model-View-Controller (MVC) is a software architecture pattern Originally formulated in the late 1970s by Trygve Reenskaug as

part of the Smalltalk Code reusability and separation of concerns Originally developed for desktop

Then adapted for internet applications

The MVC Pattern

5

Set of classes that describes the data we are working with Rules for how the data can be changed and manipulated May contain data validation rules Often encapsulate data stored in a database

as well as code used to manipulate the data

Most likely a Data Access Layer of some kind It doesnt have significance in the framework

Apart from giving the data objects

Model

6

Defines how the applicationrsquos user interface (UI) will be displayed May support master views (layouts) May support sub-views (partial views or controls) Web Template to dynamically generate HTML

View

7

The core MVC component ndash holds the logic Process the requests with the help of views and models A set of classes that handles

Communication from the user Overall application flow Application-specific logic

Every controller has one or more actions

Controller

8

Incoming request is routed to a Controller For web HTTP request

Controller processes request and creates a presentation Model Controller also selects appropriate result (view)

Model is passed to View View transforms Model into appropriate output format (HTML) Response is rendered (HTTP response)
