What is the Difference Between MVC and MVVM?

Read Time:3 Minute, 54 Second

When you’re deciding between MVC and MVVM, you need to take several factors into account. Both approaches have their benefits, but what makes one better than the other? The most obvious difference is the model. In MVC, the model communicates directly with the View and Controller. MVVM, on the other hand, uses a model-view-model architecture. The model communicates with the Controller only indirectly.

Model-View-Controller

MVVM differs from MVC in many ways, including the view-model separation. Both approaches use a model class to hold information about the application’s data, and both include the controller. A model class is often used in conjunction with a controller to encapsulate caching and data access. The view, on the other hand, is the part of the application that the end user interacts with. It takes liberties with data in order to present it to the user. In MVVM, the view is active, while a passive view has no concept of the model. Both controllers and presenters are fully responsible for manipulating the data.

MVVM is often used to replace MVC, but it is important to remember that MVVM does not eliminate the controller role. Instead, the controller communicates with the view model, which does the logical work. Model-View-Controller and MVVM are often used interchangeably, but MVC is the more commonly known and favored design pattern. MVVM is more suited for large applications where many interacting views must be handled.

Back-End Logic

Both approaches make use of a model in the development process, which enables separating the logic of a web application from the user interface. This separation allows the application to be flexible, and to work with data from an API. MVVM also helps programmers structure and organize their code. It also facilitates separation of GUI development from back-end logic. Model-View-Controller and MVVM are similar in structure and purpose.

Data Binding 

The difference between MVC and MVVM lies in the approach to data binding. Both approaches use a view model to store data and related logic and a model that represents the data transfer between the view and controller components. The model object can then be used by the controller to manipulate the data and render the results. Data binding between MVC and MVVM is possible in a single page application. To see more information about how each approach works, please read the following article.

Model-Driven Architectures

MVVM and MVC are model-driven architectures, so the view model communicates with the model. However, the view model does not need to understand the other architecture. Data-binding handles this communication. The concepts will be explored in a draft post, which puts these concepts into concrete code. It will be interesting to see how each approach works in practice. This article is not intended to be a complete replacement of MVC, but rather a complement.

As an example, in MVC, data binding enables developers to logically group related actions on the Controller. This pattern works well for large teams of developers, but it lacks formal validation support and is difficult to maintain, particularly when using multiple technologies. Data management and code reuse is also difficult, and it becomes a messy process when the view controllers need to manually set the properties of each subview. A common complaint about MVVM is the difficulty of reusing code across multiple applications.

Reactive Programming

There are many ways to build web applications, and two popular styles are MVC and MVVM. Both have their own strengths and weaknesses, and each is an effective method for certain applications. This article will explain the differences between the two popular web development styles and their respective applications. In addition, we’ll compare the advantages and disadvantages of both approaches, and look at some practical examples. Listed below are a few of the key differences between MVC and MVVM.

MVVM uses a pattern called Flux, which tells app views how to interact with each other. This pattern enables the ViewModel to update itself, but still requires a Controller. MVVMs is also associated with data binding, making it popular in desktop applications. MVC is also associated with views that display data. MVVM applications are typically loosely coupled, but they can reference a service layer.

Conclusion:

MVVM is another Android architecture that separates business logic from presentation logic. While MVC offers a simpler structure, it can be too complicated for large projects. With MVVM, business logic can be separated from presentation logic and can be easily reused across many components. MVVM is not for everyone, and may be better for simple projects. However, you should consider your application’s needs before choosing between MVVM and MVC here.
