Student Database Management System (SDMS)

A simple Student Database Management System combining a C++ backend and a static frontend.

Project Overview

• Description:: Minimal student database demo with a C++ program (backend.cpp) that reads/writes data.json, and a web frontend (frontend/) (HTML/JS/CSS) for interaction and display.
• Language/Tech:: C++17, header-only nlohmann/json (included under include/nlohmann/json.hpp), plain HTML/CSS/JavaScript for the frontend.

Quick Start

• Open Project:: Open the project folder at c:\Users\Desktop\SDMS in your editor.

Prerequisites

• C++ Compiler:: g++ (MinGW / GCC) or MSVC (cl).
• Python (optional):: python for serving the frontend via a simple HTTP server (recommended for correct file/URL behavior).
• Web Browser:: Modern browser (Chrome, Edge, Firefox).

Build & Run — Backend (PowerShell)

• Compile with g++:

cd C:\User\Desktop\SDMS
g++ -std=c++17 -I include -o backend.exe backend.cpp

• Compile with MSVC (Developer Command Prompt / cl):

cd C:\Users\Desktop\SDMS
cl /EHsc /I include backend.cpp

• Run backend:

.\backend.exe

Notes:

• The project uses the header-only nlohmann/json library already present at include/nlohmann/json.hpp so no extra package installation is required for JSON support.
• The backend reads/writes data.json in the project root. Ensure the process has write permissions to that file.

Run — Frontend

• Easiest: open frontend/index.html directly in a browser.
• Recommended (serves files over HTTP):

cd C:\Users\Desktop\SDMS\frontend
python -m http.server 8000

Then open http://localhost:8000/index.html in your browser.

Project Structure

• backend.cpp: C++ backend program that manipulates data.json.
• data.json: The JSON data store for student records.
• frontend/:
  • index.html: Frontend UI.
  • app.js: Frontend JavaScript logic.
  • style.css: Frontend styles.
  • run.txt: (auxiliary file; inspect for notes)
• include/nlohmann/json.hpp: Header-only JSON library used by backend.cpp.

Data format

• data.json contains student records in JSON format. Open it to inspect or modify sample entries. The backend and frontend expect JSON objects/arrays — check backend.cpp and frontend/app.js for exact field names.

Troubleshooting

• Compiler errors about headers:: Ensure the -I include flag is used so the compiler finds nlohmann/json.hpp.
• Frontend fetch/network errors:: Serving via python -m http.server avoids CORS/file:// restrictions. If opening the file directly causes issues, use the HTTP server.
• Permission errors writing data.json:: Run the backend from a directory where you have write access, or run your terminal as an elevated user if necessary.

Contributing

• Improvements: Add detailed build scripts, a small REST API, or a database-backed store.
