What ASP.net means by three-tier architecture

What ASP.NET means by three-tier architecture is the MVC architecture.

MVC is a pattern for creating Web applications using the MVC (Model View Controller) design.

The Model represents the core of the application (for example, a list of database records).

View displays the data (database records).

Controller processes input (writing to database records).

The MVC pattern also provides full control over HTML, CSS, and JavaScript.

The Model is the part of the application that handles the logic of the application data.

Often the model object is responsible for accessing data in the database.

View is the part of the application that handles the display of data.

Often views are created from model data.

Controller is the part of the application that handles user interaction.

Often the controller is responsible for reading data from the view, controlling user input, and sending data to the model.

MVC layering helps manage complex applications because you can specialize in one aspect at a time. For example, you can focus on view design without relying on business logic. It also makes it easier to test the application.

MVC layering also simplifies group development. Different developers can work on the view, controller logic, and business logic at the same time.
