Student Registration Management System

Complete two-tier desktop application for managing student registration data with secure authentication and comprehensive CRUD operations.

Project Overview

A full-stack desktop application developed for Skills International School using C# Windows Forms and SQL Server Express. The system implements a two-tier client-server architecture with robust authentication, comprehensive student data management, and real-time database connectivity through ADO.NET. Features include secure login with parameterized queries, dynamic data retrieval via ComboBox selection, client-side validation, and complete CRUD operations with user confirmations.

Challenge

Building a secure, reliable desktop application for managing sensitive student data with proper authentication, validation, and data integrity. The system needed to prevent SQL injection attacks, ensure data accuracy through validation, and provide an intuitive interface for non-technical staff while maintaining robust database operations.

Solution

Developed a two-tier architecture using C# Windows Forms for the presentation layer and SQL Server Express for data persistence. Implemented parameterized SQL queries to prevent injection attacks, created a dedicated Users table for authentication, designed auto-incrementing IDENTITY columns for unique registration numbers, and built comprehensive client-side validation (age verification, phone number format, required fields). Added user confirmation dialogs for destructive operations and dynamic ComboBox population for efficient record lookup.
