Project Overview

CEMS is a software system developed to centralize and automate all aspects of exam management. It enhances the efficiency and reliability of handling different types of exams through features like automated grading, data analysis, anti-cheating mechanisms, and a user-friendly interface. The system is designed to be modular, scalable, and adaptable for future requirements.

Features

1. Question Bank Management:

   • Allows instructors to create and manage a bank of questions.
   • Supports multiple subjects and courses with uniquely identifiable questions.

2. Exam Creation:

   • Instructors can generate exams by selecting questions from the question bank.
   • Each exam has a unique identifier, defined duration, point allocations, and customizable instructions.

3. Exam Execution:

   • Manual Mode: Provides students with downloadable exam files for offline completion.
   • Automated Mode: Allows students to answer questions directly in the system UI.

4. Automated Grading and Anti-Cheating:

   • Automatic grading functionality with configurable scoring.
   • Anti-cheating mechanism through pattern detection in student answers.

5. Data Processing and Analytics:

   • Statistical calculations (average, median, score distribution) for exams.
   • Detects and flags potentially identical errors across submissions.

6. User Management and Security:

   • User authentication and role-based access control.
   • Import utility for integrating user data from external systems.

Technologies Used

• Backend: Java
• Frontend: JavaFX for user interface components
• Database: Relational database for user data, exams, and analytics
• Network: TCP/IP for local network operations (initial phase)

System Architecture

This project follows a full-stack architecture:

• Frontend: JavaFX-based UI that allows interaction with the system.
• Backend: Java backend logic and a relational database handling data persistence and business logic.
• Network Configuration: Operates over a LAN in its first phase, with future expansions to support web-based access.

Installation

1. Clone the Repository:

   git clone https://github.com/your-username/CEMS.git
   cd CEMS

2. Setup Database:

   • Configure a relational database to store user and exam data.
   • Import any necessary table structures or use the provided scripts if available.

3. Run the Application:

   • Open the project in Eclipse or any compatible Java IDE.
   • Compile and run the main application.

Usage

1. User Login: Authenticate using provided credentials.
2. Managing Exams:
