## Overview

This is a console-based student and academic-record manager. A user selects an operation from the menu; the program handles student records, enrollment, marks and GPA, student search, and course and department browsing or creation, issuing SQL commands to SQL Server. The implementation is concentrated in one file, so feature nodes share its path. The README documents capabilities beyond the sampled excerpts; their menu-level presence is represented, but uncertain internal call wiring is omitted.

Main entry points: [`StudentManagementSystem/Program.cs`](https://github.com/simobin/studentmanagementsystem/blob/main/StudentManagementSystem/Program.cs) (Menu and dispatch), [`Database/Database.sql`](https://github.com/simobin/studentmanagementsystem/blob/main/Database/Database.sql) (SQL Server database)
