Question



The V components in MVC are responsible for:

A.

User interface.

B.

Security of the system.

C.

Business logic and domain objects.

D.

Translating between user interface actions/events and operations on the domain objects.

Correct option is A


In the Model-View-Controller (MVC) architectural pattern:
· The V (View) component is responsible for the User Interface (UI).
· It is the presentation layer that displays the data (model) to the user and sends user commands to the controller.
Information Booster:
1. Components of MVC:
· Model: Manages the data, logic, and rules of the application.
· View: Handles the presentation and user interface.
· Controller: Manages the input, processes user commands, and updates the model or view.
2. Responsibilities of the View Component:
· Displays data from the model to the user.
· Captures user input and forwards it to the controller.
· Acts as a bridge between the model (data) and the controller (logic).
3. Examples of View Components:
· UI components like buttons, forms, tables, and charts in desktop, mobile, or web applications.
· Technologies: HTML, CSS, JavaFX, or front-end frameworks like React.
Additional Knowledge:
· Option (b): Security of the system is a part of application-level logic or middleware, not the view layer.
· Option (c): Business logic and domain objects are handled by the Model in the MVC architecture.
· Option (d): Translating between user interface actions and domain object operations is the responsibility of the Controller.
