The Model in a Model-View-Controller (MVC) application controls the application’s state and non-UI-specific behaviour. The persistence, display, and business logic may all use the same model class in simple applications. However, a solution that fits all typically cannot handle complicated applications. Different model types (classes) with various responsibilities might be sensible. This blog will explore “What Are the Different Types of Models in MVC?”. Join the MVC Training In Chennai and learn the ins and outs of Model-View-Controller architecture and excel in web application development.
Domain Model
Developers often encapsulate complex business logic within a domain model. This domain model remains independent of infrastructure concerns and is well-suited for easy validation through unit tests. The domain model typically incorporates abstractions and services that enable the Controller to operate at a higher level of abstraction. It keeps low-level plumbing code from cluttering the Controller, making testing more challenging. Additionally, the domain model includes interface definitions for services, repositories, and other elements used by the application. It also encompasses persistence-agnostic entities and some services representing the state and behaviour of the application’s business logic.
View Model
The concept of a ViewModel is familiar to many developers. Especially those who have experience with application frameworks following the Model-View-ViewModel paradigm. In an MVC web application, a ViewModel is designed to contain only the information required by a View for display. In the context of ASP.NET MVC, ViewModel classes can also simplify model binding. Generally, ViewModel types serve as data structures. Any logic they may include should be tailored to assist the View in rendering data. It’s common to have various ViewModel classes, each customized to meet the exact requirements of individual Views.
Binding Model
Occasionally, making a type exclusively for model binding could be advantageous. Usually, these kinds are just data containers without any behaviour. By preventing users from binding to Model properties not available on the posted form, a binding model can help with security issues with ASP.NET MVC model binding.
API Model
If your application provides an API, you can define custom API model types to separate the external data format from the internal domain model of your app. By doing this, you can modify the internal model types without affecting any clients who might be accessing the publicly available APIs. These types will serve as both a ViewModel and a BindingModel for APIs because clients often employ exposed API models for read and write activities.

Persistence Model
Some applications utilize unique classes that closely match how data is stored and accessed, frequently resulting from automated algorithms that create these classes based on a database plan. Even though it would seem like an intelligent idea to embed business logic in these classes and use them as the core model for the application, there are situations in which it is advantageous to have a different domain model from this persistence model. In these circumstances, the classes in charge of managing data storage (such as repositories) handle transporting data between these various models.
If you’re using Entity Framework, it can typically connect your primary Model to the storage of data directly. It reduce the need for a separate model solely for data storage.
The Different Types of Models in MVC can be employed depending on the complexity and requirements of your web application. Each type of Model serves a specific purpose and helps maintain a structured, maintainable, and scalable codebase.
