Survey application

**1. Introduction:** - The Survey Application is designed to offer users a platform where they can access sets of questions and submit answers for evaluation. Developed using React for the frontend, .NET Core for the backend, and SQL Server for the database, this application aims to provide an efficient and user-friendly experience. Additionally, seamless integration with a payment gateway and a robust UX design will be incorporated. **2. Functional Requirements:** **2.1 User Authentication and Authorization:** - Users should be able to register, log in, and log out securely. - Different user roles (e.g., admin, regular user) with corresponding access levels should be implemented. **2.2 Survey Functionality:** - Users should be presented with sets of questions based on selected categories or topics. - Each question set should have a defined time limit for completion. - Users should be able to submit answers within the allocated time frame. - The system should provide immediate feedback on correct and incorrect answers. - Users should have the option to review their answers before submission. - Results should be calculated based on the number of correct answers and presented to the user upon completion. - Progress tracking for completed and pending question sets should be available. **2.3 Payment Gateway Integration:** - Integration with a payment gateway to grant access to question sets based on subscription plans or pay-per-use model. - Secure handling of payment transactions and user billing information. **2.4 Admin Panel:** - An administrative interface for managing question sets, user subscriptions, and reported content. - Ability to create, edit, and delete question sets. - Monitoring user activity and performance metrics. **3. Non-Functional Requirements:** **3.1 Performance:** - The application should be responsive and performant, with minimal latency during question set retrieval and submission. - Database queries should be optimized for efficient data retrieval. **3.2 Security:** - Implementation of secure authentication mechanisms (e.g., JWT tokens). - Protection against common security threats such as SQL injection and cross-site scripting (XSS). - Encryption of sensitive user data, including passwords and payment information. **3.3 Scalability:** - The application architecture should be scalable to accommodate a growing user base and increasing question sets. - Load balancing and caching mechanisms should be considered for scalability. **4. UX Design Requirements:** - A clean and intuitive user interface (UI) design with clear navigation and organization of question sets. - Consistent branding and color schemes to enhance user engagement. - Mobile responsiveness for accessibility across devices. - Progress indicators and informative feedback to guide users through the question answering process. **5. Technology Stack:** - Frontend: React.js - Backend: .NET Core - Database: SQL Server - Payment Gateway: Integration with a secure payment gateway provider. **6. Additional Considerations:** - Regular backups of the database to prevent data loss and ensure continuity of service. - Implementation of error logging and monitoring for proactive issue resolution. - Compliance with relevant data protection regulations (e.g., GDPR, CCPA). **7. Constraints:** - Development should adhere to project timelines and budget constraints. - Regular communication and collaboration between development teams for seamless integration of frontend and backend components. **8. Acceptance Criteria:** - Successful implementation of all functional and non-functional requirements. - User acceptance testing (UAT) to ensure the application meets user expectations. - Deployment to a production environment with proper documentation and support resources. **9. Glossary:** - Definitions of key terms and concepts used throughout the requirement specification. **10. References:** - Any relevant documentation, APIs, or external resources used in the development process.
