Three Tier Architecture vs MVC Architecture

Introduction

In this blog, we look at the difference between three-tier architecture and MVC.

Comparison of Three Tier Architecture vs MVC Architecture

Three-tier architecture never communicates directly to the data access layer, in three-tier architecture all the data communication must pass through the middle tier.
That's why the three-tier architecture is linear.
Three-tier is nothing but Presentation Layer which is present UI related things, a business logic layer that contains all the calculation, logic related parts, and last Data Access Layer(Model).
But in MVC Architecture is triangular.
The view sends updates to the controller, the controller updates the model, and then view directly gets updates from the model.
MVC contains Model (Data), View (UI), and Controller (Logic).

Still not clear about the difference, because all i know in MVC, view cannot directly access the Model. it has to be communicated by Controller (which means the data communication must pass through the middle tier) before it can be presented in the View
