 Model-view-controller - Wikipedia, the free encyclopedia
Model-view-controller (MVC) is a software architecture that separates an application's data model, user interface, and control logic into three distinct components so that modifications to one component can be made with minimal impact to the others.
Complex controllers are often structured using the command pattern to encapsulate actions and simplify extension.
MVC is often seen in web applications, where the view is the HTML page and the code which gathers dynamic data for the page.

 Pattern Model View Controller - Web Application Component Toolkit
In MVC, The controller is NOT a Mediator between the view and the model.
Model View Controller MVC is a time tested method of separating the user interface of an application from its domain logic.
The controller is considered a Strategy that the view uses for input.

 Model-View-Controller (Microsoft Patterns)
It is important to note that both the view and the controller depend on the model.
Therefore, it is important to keep the view in mind when coding the model.
Because the view is separated from the model and there is no direct dependency from the model to the view, the user interface can display multiple views of the same data at the same time.

 (ootips) Model-View-Controller
A controller accepts input from the user and instructs the model and viewport to perform actions based on that input.
The MVC paradigm is a way of breaking an application, or even just a piece of an application's interface, into three parts: the model, the view, and the controller.
The controller interprets mouse and keyboard inputs from the user and maps these user actions into commands that are sent to the model and/or viewport to effect the appropriate change.

 model-view-controller - a Whatis.com definition
In object-oriented programming development, model-view-controller (MVC) is the name of a methodology or design pattern for successfully and efficiently relating the user interface to underlying data models.
A Controller, which represents the classes connecting the model and the view, and is used to communicate between classes in the model and view.
A Model, which represents the underlying, logical structure of data in a software application and the high-level class associated with it.

 How to use Model-View-Controller (MVC)
The model is totally "unaware" of the existence of either the view or the controller and of its participation in an MVC triad.
In either case, the string model is a completely passive holder of the string data manipulated by the view and the controller.
In the MVC paradigm the user input, the modeling of the external world, and the visual feedback to the user are explicitly separated and handled by three types of object, each specialized for its task.

 Model View Controller
In fact for the MVC pattern the idea of model and view switching requires that the substitute view or model have the exact same interface with the controller than the original view or model otherwise the magical switch is broken.
An easy way to understand MVC: the model is the data, the view is the window on the screen, and the controller is the glue between the two.
The Controller has a life of its own that must be understood in the context of providing the "control" portion of "command and control." In EmbeddedSystems the Controller is most often some kind of machine interface that provides a means of flipping doors, ringing bells, and shining lights.

 MVC design pattern brings about better organization and code reuse
Model-View-Controller (MVC) is a widely used software design pattern that was created by Xerox PARC for Smalltalk-80 in the 1980s.
Presented with a number of reusable building blocks in the model and the view, the controller picks and chooses which blocks are needed to handle specific processing and display requirements.
Because the model is self-contained and separate from the controller and the view, it's much less painful to change your data layer or business rules.

 MVC Pattern
Views in MVC are associated with controllers that update the model as necessary when a user interacts with an associated view.
The Model View Controller pattern was invented in a Smalltalk context for decoupling the graphical interface of an application from the code that actually does the work.
The View should implement the update method by querying the model (actually the Observable t) for the changes it needs and then make appropriate changes to the view itself.

 Refactoring to Model-View-Controller
I also knew that the term "controller" is short for "code that handles the interaction between model and view, and/or functions outside the scope of either."
I knew that the way people describe MVC is "model-view separation," which means, "separate the code that handles your data (the 'data model') from the code that handles displaying that data (the 'view')," and I knew that's a good thing.
For now, let's move these members into the new View object as well.

 Model view controller triad
The actual implementation of the controller object can vary quite a bit, but the idea of an object to 'transform' events to changes in data and execution of methods is the essence of this pattern.
In contrast, objects in object oriented programming are composed of methods and data members that attempt to model something from the domain of interest.
The best models are fully encapsulated, meaning that they implement every aspect of that real world object of interest to the domain of interest, and that they don't have any extra code that doesn't model the real world.

 Apache Struts - Struts Action Framework - User Guide - Introduction
But, a direct link between the Model and the View is not practical for web applications, so we modify the classic MVC arrangement so that it would look less like a loop and more like a horseshoe with the controller in the middle.
The original MVC pattern is like a closed loop: The View talks to the Controller, which talks to the Model, which talks to the View.
The Controller is focused on receiving requests from the client (typically a user running a web browser), deciding what business logic function is to be performed, and then delegating responsibility for producing the next phase of the user interface to an appropriate View component.

 Observer and Observable
Its central characteristics are that the model, the controllers, and the views are treated as separate entities, and that changes made to the model should be reflected automatically in each of the views.
The class combines the features of both a view (it textually displays the value of the current state of the model) and a controller (it allows the user to enter a new value for the state of the model).
Typically, the model is a subtype of Observable and the view is a subtype of observer.

 PGUI: Model-View-Controller
The separation of the controller and the view is based on the possibility of implementing several different controllers for one single view.
Anytime the model is changed, each view of the model is notified so that it can change the visual representation of the model on the screen.
The controller communicates with the view to determine whet object is being manipulated.

 ColdFusion + Model-View-Controller = CFMVC @ COLDFUSION DEVELOPER'S JOURNAL
Model-controller, as the name suggests, handle all interaction with the model layer but it's important to remember that code here is not intended for reuse and extra features for this application can be added for example an e-mail or calling a web service.
The model layer handles all core data interaction whether with a database, XML files or any other data store along with other business interactions.
All code in the model layer must be written so it can be reused in other applications and should not use session, application or request variables; rather, values should be passed in via attributes.

 Model View Controller
Smalltalk provides mechanisms to link models, views and controllers in some standard way in order for a model to communicate state changes to every attached view (there can be several, as you can see).
Model state changes happen either because a controller issued some command or for some internal reason.
The argument is that, because the web works by returning HTML views to clients, an MVC design is inherent in server-side web programming.

It is based on the Model-View-Controller (MVC) pattern, which was the central concept behind the Smalltalk-80 user interface.
The View is the display of the model, and the Controller takes care of the user interface interaction with the user input.
A view is normally passed as a reference to the controller object and can access some of the variables in the controller.

 How to use Model-View-Controller (MVC)
View release causes it to remove itself as a dependent of the model, send the message release to the controller, and then send release to any subViews.
You will need to flesh out the information given here by looking at the way familiar kinds of views and controllers -- such as workspaces, browsers and file lists -- are set up.
Suppose that the data object -- the string in the above example -- changes as a result of messages from objects other than its view or controller.

 Java BluePrints - J2EE Patterns
Controller - The controller translates interactions with the view into actions to be performed by the model.
This can be achieved by using a push model, where the view registers itself with the model for change notifications, or a pull model, where the view is responsible for calling the model when it needs to retrieve the most current data.
The MVC architecture has its roots in Smalltalk, where it was originally applied to map the traditional input, processing, and output tasks to the graphical user interaction model.
