Description

BookBazaar is an online bookstore designed to manage book inventories, user orders, and data analytics.

Technical Specifications

1. Backend: ASP.NET Core Web API with C#
2. Database: Azure Cloud SQL Server
3. APIs: RESTful APIs
4. Authentication: JWT (JSON Web Tokens) for secure user authentication.
5. Frontend: React (TypeScript)
6. Cloud Platform: Azure
7. DevOps Tools: Git for version control; CI/CD pipeline using Jenkins or Azure DevOps.
8. Testing: xUnit for unit testing; Postman for API testing; Selenium for UI testing.

Architecture

1. User: Handles user registration, authentication, and profile management.
2. Inventory: Manages books' details, stock levels, and categorization.
3. Order: Processes orders, manages shopping carts, and tracks order status.
4. Payment: Processes payments and handles payment gateway integrations.
5. Recommendation: Provides personalized book recommendations to users based on their browsing and purchase history.
6. Analytics: Gathers and analyzes data for business insights, like popular books, sales trends, etc.

Key Features

User

• User registration and login functionality.
• Profile management (update user details, view purchase history).
• Role-based access control (admin, user).

Inventory

• CRUD operations for book details (title, author, genre, price, stock quantity).
• Search functionality (by title, author, genre).
• Book categorization (e.g., fiction, non-fiction, educational).

Order

• Shopping cart management.
• Order placement and confirmation.
• Order status tracking (placed, shipped, delivered).

Payment

• Integration with a payment gateway (e.g., Stripe, PayPal).
• Secure handling of payment transactions.
• Support for different payment methods (credit/debit card, net banking).

Recommendation

• Algorithm to suggest books based on user preferences and previous orders.
• Feature to rate and review books.

Analytics

• Dashboard for sales data visualization.
• Reports on top-selling books, customer demographics, and sales trends.
• Real-time data updates.

Development Approach

1. Kanban using Trello at https://trello.com/b/1k7otVhD/bookbazaar
2. TDD (Test-Driven Development): Write tests before coding features.
3. Code Documentation: Comment code and maintain clear documentation for each model.
4. Version Control: Use Git with feature branching strategy.

Project Deployment

• Develop a CI/CD pipeline for automated testing and deployment.

Final Deliverables

• Source code.
• API documentation.
• User manual.
• Test cases and results.
• Deployment scripts and instructions.

Testing

1. Unit Testing:

   • Write unit tests for individual components within each modl.
   • Utilize xUnit.net as your testing framework.
   • Ensure that you cover edge cases, failure modes, and happy paths.

2. Integration Testing:

   • Test the interactions between models to validate the integrated system behavior.
   • Mock external dependencies or use in-memory databases like SQLite for .NET to simulate real-world scenarios.
   • Tools like Postman or Swagger can be used for testing RESTful APIs.

3. Functional Testing:

   • Conduct end-to-end testing to validate the application from a user's perspective.
   • Automate user interactions using a tool like Selenium for web applications.

4. Load Testing:

   • Test how your system behaves under high load conditions.
   • Use tools like JMeter or Apache Bench to simulate multiple users accessing your application concurrently.
   • Focus on identifying bottlenecks, latency issues, and potential crashes.

5. Security Testing:

   • Validate the security aspects of your application.
   • Ensure that user data is protected, authentication mechanisms are robust, and APIs are secured against common vulnerabilities like SQL injection, XSS, etc.
   • Tools like OWASP ZAP can be used for security testing.

6. Code Quality Analysis:

   • Use tools like SonarQube to analyze your code for quality issues, code smells, and technical debt.
   • Ensure coding standards are maintained and best practices are followed.

7. Performance Testing:

   • Monitor and test the performance of your application, focusing on response times, resource usage, and throughput.
   • Use profiling tools to identify performance issues and optimize code where necessary.

8. User Acceptance Testing (UAT):

   • Engage real users or stakeholders to test the application in a production-like environment.
   • Gather feedback on usability, functionality, and overall user experience.

9. Continuous Integration and Deployment (CI/CD) Pipeline Validation:

   • Ensure that your CI/CD pipeline correctly builds, tests, and deploys your application.
   • Automate your testing as part of the pipeline to ensure that changes do not break the application.

10. Monitoring and Logging:

    • Implement monitoring and logging to track the health and performance of your application in real-time.
    • Use tools like ELK Stack or Prometheus and Grafana for logging and monitoring.

11. Documentation and Code Review:

    • Ensure your code is well-documented and easy to understand.
    • Conduct code reviews with peers or mentors to get feedback and identify potential issues.

12. Compliance and Best Practices:

    • Ensure your application complies with industry standards and best practices.
    • Stay updated with the latest .NET guidelines and architectural best practices.
