Question

Eric was told that Visualforce is part of the MVC paradigm. In this context, what does MVC stand for?

1) Master Control Variable
2) Master Class Variable
3) Model View Controller
4) Model Variable Controller

Answer 1

MVC stands for Model View Controller, and it is a paradigm which separates an application into three interconnected components to manage complexity and enhance maintainability. Option 3 is the correct answer.

Step-by-step explanation:

Eric was told that Visualforce is part of the MVC paradigm, which stands for Model View Controller. The MVC paradigm is a design pattern widely used in software development for segregating the application into three interconnected components. This separation of concerns allows developers to manage complexities when building user interfaces and supports scalability and maintainability.

In the MVC pattern:

• The Model represents the data and the business logic of the application. It is responsible for managing the rules of the application, the database records, and essentially everything that relates to the data or how the data is manipulated.
• The View corresponds to the elements of the user interface, such as text, dropdown menus, and buttons. The view takes data from the model and displays it to the user.
• The Controller acts as an intermediary between the Model and the View, receiving user input and deciding what to do with it. It controls the data flow into model objects and updates the view whenever data changes.

Visualforce, being part of Salesforce's suite of tools, leverages the MVC pattern to allow developers to create custom user interfaces with controllers written in Apex, Salesforce's proprietary programming language. Thus, the correct answer to the question is option 3) Model View Controller.
