MVC (Model-View-Controller) is a software architectural pattern that separates an application into three interconnected components: 1. *Model*: Represents the data and business logic, managing data storage and retrieval. 2. *View*: Handles user interface and presentation, displaying data to the user. 3. *Controller*: Manages user input and requests, interacting with the model and view to update data and render the UI. MVC is important because it: 1. *Separates Concerns*: Decouples components, making development, testing, and maintenance easier. 2. *Promotes Reusability*: Components can be reused across multiple applications. 3. *Improves Flexibility*: Allows for easy changes to individual components without affecting others. 4. *Enhances Testability*: Components can be tested independently, reducing complexity. 5. *Supports Scalability*: Makes it easier to add new features and components as the application grows. MVC is widely used in web development, desktop applications, and mobile app development, making it a fundamental concept in software engineering. Its importance lies in its ability to create maintainable, flexible, and scalable software systems. read less

MVC (Model-View-Controller) is a design pattern that separates an application into three components:Model - Manages data and business logic.View - Handles the display/presentation.Controller - Manages user input and updates the Model and View.This separation helps organize code and improve maintainability.

Both Spring MVC and Struts are popular Java-based web frameworks, but they have different design principles, architectures, and use cases. The choice between them depends on your project requirements, team experience, and personal preferences. Here's a brief comparison: *Spring MVC:* 1. _More flexible and modular_ 2. _Tighter integration with Spring ecosystem_ 3. _Annotation-based configuration_ 4. _Supports both Java and Kotlin_ 5. _More extensive community support_ *Struts:* 1. _More mature and established_ 2. _XML-based configuration_ 3. _Strong emphasis on MVC pattern_ 4. _Robust support for internationalization and localization_ 5. _Less tightly coupled with other frameworks_ Consider Spring MVC if: - You're already using Spring in your project - You prefer annotation-based configuration - You need a more modular and flexible framework Consider Struts if: - You're working on a legacy project already using Struts - You prefer XML-based configuration - You need strong support for internationalization and localization Ultimately, both frameworks can help you build robust web applications. Assess your project needs and team expertise to make an informed decision. read less

MVC (Model-View-Controller) separates concerns by dividing an application into three interconnected components: 1. *Model*: - Represents the data and business logic - Manages data storage and retrieval - Encapsulates data and behavior - Notifies views of changes 2. *View*: - Responsible for rendering the user interface - Displays data provided by the model - Receives user input and sends it to the controller - Does not contain business logic 3. *Controller*: - Handles user input and requests - Interacts with the model to retrieve and update data - Selects and invokes the appropriate view - Does not contain business logic or rendering code By separating concerns, MVC provides several benefits: - *Decoupling*: Components are independent and can be modified or replaced without affecting others - *Reusability*: Models, views, and controllers can be reused across multiple applications - *Testability*: Components can be tested individually, making it easier to identify and fix issues - *Maintainability*: Code organization and separation of concerns make it easier to maintain and update the application MVC promotes a clean, modular, and scalable architecture, making it easier to develop and maintain complex applications. read less
