## Overview

QLBD2 is an ASP.NET MVC student administration and grade-management application. Users access role-protected dashboards; account actions handle sign-in and account maintenance, while management actions cover courses and grades. The controllers use an Entity Framework context to query and save student, class, course, account, and result records. The tree shows corresponding dashboard and login views, but the excerpts do not establish client-side request wiring or the full details of each dashboard interaction, so those links are omitted.

Main entry points: [`QLBD2/Controllers/DashboardController.cs`](https://github.com/darkeyez-reborn/webqlbd/blob/master/QLBD2/Controllers/DashboardController.cs) (Dashboard actions), [`QLBD2/Models/Model1.Context.cs`](https://github.com/darkeyez-reborn/webqlbd/blob/master/QLBD2/Models/Model1.Context.cs) (Entity Framework context), [`QLBD2/Controllers/TaiKhoanController.cs`](https://github.com/darkeyez-reborn/webqlbd/blob/master/QLBD2/Controllers/TaiKhoanController.cs) (Account actions), [`QLBD2/Controllers/HomeController.cs`](https://github.com/darkeyez-reborn/webqlbd/blob/master/QLBD2/Controllers/HomeController.cs) (Home pages)
