Online Examination System: Computer Engineering Guide
1. Introduction
Overview of the project.
Objectives of the system: Develop an online platform for conducting examinations efficiently and securely.
Scope of the system: Applicable for educational institutions, certification programs, and recruitment processes.
2. Requirements Analysis
Functional Requirements:
· - User registration and authentication for students and examiners.
· - Creation and management of exams, including question banks and schedules.
· - Conducting exams with features like time limits and random question generation.
· - Automatic evaluation for objective questions and manual evaluation for subjective answers.
· - Result generation and analytics for performance review.
Non-Functional Requirements:
· - Scalability to handle large numbers of concurrent users.
· - High security to prevent cheating and ensure data integrity.
· - User-friendly interface for both students and administrators.
3. System Design
Architecture:
· - Client-server model with a web-based frontend and backend for processing and data management.
· - Integration with proctoring tools for exam monitoring.
Data Flow Diagrams (DFDs):
· - Level 0: Overview of data flow from login to result generation.
· - Level 1: Detailed processes for exam setup, conduct, and evaluation.
Database Design:
· - Tables: Users, Exams, Questions, Answers, Results.
4. Technology Stack
Frontend:
· - Web application development using React.js, Angular, or Vue.js.
Backend:
· - Python (Flask/Django) or Node.js for API development.
· - Proctoring APIs for live monitoring.
Database:
· - SQL (PostgreSQL, MySQL) or NoSQL (MongoDB, Firebase).
Cloud Services:
· - AWS, Google Cloud, or Azure for hosting and scalability.
5. Implementation
User Authentication:
· - Implement secure login using OAuth or JWT.
· - Allow role-based access for students, teachers, and administrators.
Exam Creation:
· - Develop modules for question bank management and exam scheduling.
· - Include options for different question types (MCQs, short answers, essays).
Exam Conduct:
· - Implement a real-time exam module with features like timers and randomization.
· - Integrate proctoring tools to monitor and flag suspicious activities.
Result Management:
· - Automate scoring for objective questions and provide tools for manual evaluation of subjective answers.
· - Generate detailed performance analytics for students and administrators.
6. Security
Encrypt sensitive data during storage and transmission.
Implement anti-cheating mechanisms like browser lockdown and live proctoring.
Ensure system integrity through regular audits and updates.
7. Testing
Unit Testing: Validate individual components such as user authentication and exam modules.
Integration Testing: Ensure seamless communication between frontend, backend, and proctoring tools.
System Testing: Test the entire system for usability and reliability.
Performance Testing: Evaluate system performance under high user loads.
8. Deployment
Deploy the application on cloud platforms for scalability and reliability.
Provide user training and support documentation.
Set up monitoring tools for system performance tracking.
9. Maintenance and Updates
Monitor system performance and resolve issues promptly.
Regularly update the application with new features and improvements.
Incorporate user feedback to enhance functionality and usability.
