Online Examination System

Java (Core & OOP) JDBC MySQL

Project Overview

This project is a robust, Java-based online examination platform designed to manage exams, evaluate results, and securely store user data[cite: 22]. The entire backend was built using Java, leveraging Core and Object-Oriented Programming (OOP) concepts for a clean and scalable architecture. For database operations, it integrates Java Database Connectivity (JDBC) with a MySQL server to ensure reliable and secure data management.

Key Features

User Authentication: Implemented a secure user login system to differentiate between administrators and test-takers.
Question Bank Management: Developed functionality for administrators to create, update, and manage a repository of questions for various subjects.
Timed Examinations: Engineered a timed test environment that enforces exam durations and ensures fairness.
Automated Result Generation: The system automatically evaluates answers upon submission and generates instant results for candidates.

Technical Insights

A primary challenge was designing the database schema to efficiently store relationships between users, exams, questions, and answers. This project provided deep practical experience in SQL query optimization and transaction management using JDBC. Applying OOP principles like encapsulation and polymorphism was crucial for creating reusable modules for user management and exam processing, making the system both robust and easy to maintain.
