## Overview

Student-Management-System is a web application for managing accounts, students, courses, available courses, and enrollments. Users interact through browser scripts and backend controllers; controllers dispatch to application operations, which use repositories to persist domain data. Authentication uses ASP.NET Identity and JWTs, and enrollment creation records student and course details. The README provides no capability details, and several application and frontend files were not sampled, so uncertain internal calls and frontend-to-endpoint wiring are omitted.

Main entry points: [`Backend/Infrastructure/Data/DataContext.cs`](https://github.com/leenalmahthi/student-management-system/blob/main/Backend/Infrastructure/Data/DataContext.cs) (EF data context), [`Backend/Infrastructure/Identity/usermanager.cs`](https://github.com/leenalmahthi/student-management-system/blob/main/Backend/Infrastructure/Identity/usermanager.cs) (Identity manager), [`Backend/Application/Athu/SignIn.cs`](https://github.com/leenalmahthi/student-management-system/blob/main/Backend/Application/Athu/SignIn.cs) (Sign-in and sign-up), [`Backend/Application/enrollment/CreateEnrollment.cs`](https://github.com/leenalmahthi/student-management-system/blob/main/Backend/Application/enrollment/CreateEnrollment.cs) (Create enrollment)
