Project structure is a example of layered (or n-tier) architecture , and it’s widely used in real-world enterprise applications. This Architecture Works in the Real World because it offers : Separation of concerns : Teams can work independently on UI, business logic, and data access. Testability : Business logic is isolated and easily testable. Scalability : You can swap out the UI (e.g., replace MVC with Blazor or Angular) without touching the core logic. Maintainability : Easier to onboard new developers and manage code over time. Real-World Scenario: HR & Payroll Management System Imagine a company which has thousands of employees across multiple locations. They need a system to manage: Employee records Attendance and leave tracking Payroll processing Departmental hierarchies Role-based access control How Each Layer Plays a Role Project Layer Real-Life Responsibility Example EmployeeManagementSystem.Web ASP.NET Core MVC front-end where HR staff log in, view dashboards, manage employee data EmployeeManagementSystem.Service Business logic like calculating leave balances, validating payroll rules, or applying tax slabs EmployeeManagementSystem.Repository Abstracts data access—e.g., fetching employee records, saving attendance logs EmployeeManagementSystem.Data Entity Framework Core context, migrations, and DB configuration EmployeeManagementSystem.Models POCOs like Employee , Department , LeaveRequest , PayrollSlip EmployeeManagementSystem.Tests Unit tests for service logic—e.g., verifying salary calculations or leave approval workflows
