The Model-view-controller (MVC) is a software architectural pattern that separates the representation of information from the user's interaction with it. This separation of concerns means that the model is responsible for managing the data, the view is responsible for displaying the data, and the controller is responsible for handling user input and updating the view.
The MVC pattern is often used in web applications, where the view is a web page and the controller is a web server. The model is often a database. However, the MVC pattern can be used in any type of application, including desktop and mobile applications.
What is MVC used for?
MVC stands for Model, View, Controller. It is a software architectural pattern for implementing user interfaces. It is a way of dividing an application into three parts: the model, the view, and the controller.
The model is the part of the application that handles the data. It is responsible for fetching data from a database or other source, and for storing data in memory.
The view is the part of the application that handles the user interface. It is responsible for displaying data to the user, and for handling user input.
The controller is the part of the application that handles the logic. It is responsible for deciding what to do with the data, and for sending commands to the model and view.
What is difference between MVC and MVVM?
MVC is a software design pattern for structuring code. It stands for Model View Controller. The Model View Controller design pattern divides code into three sections:
1. The "Model" section contains code related to data and business logic.
2. The "View" section contains code related to the user interface.
3. The "Controller" section contains code that connects the Model and View sections.
MVVM is a software design pattern that is similar to MVC. However, instead of having a "Controller" section, MVVM has a "ViewModel" section. The ViewModel section contains code that connects the View and Model sections.
What is the role of model view and controller in MVC architecture?
The Model View Controller (MVC) architecture is a software design pattern that is commonly used in web applications. It is a way of organizing code so that there is a separation of concerns between the different parts of the application.
The Model is responsible for the data and the business logic of the application. The View is responsible for the presentation of the data to the user. The Controller is responsible for handling the user input and interacting with the Model.
The MVC pattern is advantageous because it makes the code easier to maintain and debug. It also makes it easier to add new features to the application. What is the difference between controller and ViewModel? The controller is responsible for handling user input and invoking changes to the model or view. The ViewModel is responsible for exposing data from the model in a format that the view can bind to, and for handling user input from the view. What is difference between ViewModel and model? ViewModels are typically used in conjunction with a Model, where the Model is used to represent the data and the ViewModel is used to represent the state of the view. The ViewModel is responsible for providing the data and logic needed by the view, and it is typically bound to the view via a data binding framework.
