3. Technical Architecture Details

System architecture style

The Hafta-Test system appears to follow a Monolithic architecture style, typical of Ruby on Rails applications. This architecture style is suitable for small to medium-sized applications and allows for rapid development and easier deployment.

Technology stack

  • Backend Framework: Ruby on Rails
  • Frontend: HTML, CSS (likely with SCSS), JavaScript
  • Database: PostgreSQL (inferred from typical Rails setups)
  • Authentication: Likely using Devise gem
  • Testing: RSpec (Ruby testing framework)

Programming languages

  • Ruby
  • JavaScript

Frameworks and libraries

  • Ruby on Rails
  • Turbolinks
  • Webpacker
  • Bootsnap
  • Devise (for authentication)
  • Puma (web server)

Database technologies

  • PostgreSQL

Cloud/infrastructure platforms

The deployment platform is not explicitly specified in the repository. However, common choices for Rails applications include:

  • Heroku
  • Amazon Web Services (AWS)
  • DigitalOcean

4. API and Endpoint Documentation

Based on the repository structure, we can infer some of the likely API endpoints. However, without access to the actual routes file or controller implementations, this is an educated guess:

User Authentication

POST /users/sign_in

  • Description: Authenticate a user
  • Request Body: 
    {
  "user": {
    "email": "string",
    "password": "string"
  }
}
  • Response Body: 
    {
  "token": "string",
  "user": {
    "id": "integer",
    "email": "string",
    "username": "string"
  }
}

Transactions

GET /transactions

  • Description: Retrieve a list of transactions
  • Authentication: Required
  • Response Body: 
    {
  "transactions": [
    {
      "id": "integer",
      "amount": "decimal",
      "date": "date",
      "user_id": "integer"
    }
  ]
}

POST /transactions

  • Description: Create a new transaction
  • Authentication: Required
  • Request Body: 
    {
  "transaction": {
    "amount": "decimal",
    "date": "date"
  }
}
  • Response Body: 
    {
  "id": "integer",
  "amount": "decimal",
  "date": "date",
  "user_id": "integer"
}

Reports

GET /reports

  • Description: Generate a report
  • Authentication: Required
  • Query Parameters:
    • start_date: date
    • end_date: date
    • type: string
  • Response: A downloadable report file

5. Security Architecture

Authentication mechanisms

  • User authentication is likely implemented using the Devise gem, which provides robust authentication solutions for Rails applications.
  • JSON Web Tokens (JWT) might be used for API authentication, although this is not confirmed from the repository.

Authorization model

  • Role-based access control (RBAC) is likely implemented to differentiate between regular users and administrators.

Data encryption strategies

  • Passwords are likely hashed using bcrypt (standard with Devise).
  • HTTPS should be used for all communications to ensure data in transit is encrypted.

Compliance considerations

  • Depending on the deployment region and nature of financial data, compliance with regulations such as GDPR, PCI-DSS, or local financial regulations may be necessary.

6. Performance and Scalability

Performance expectations

  • Quick response times for transaction processing (< 1 second)
  • Efficient report generation, even for large datasets

Scalability approach

  • Vertical scaling can be achieved by upgrading server resources.
  • Horizontal scaling might require modifications to the architecture, potentially moving towards a microservices approach for certain components.

Caching mechanisms

  • Rails built-in caching can be utilized for frequently accessed data.
  • Consider using Redis for more advanced caching needs.

7. Integration Points

External system integrations

  • Payment gateways for processing transactions (not explicitly visible in the repository, but likely necessary)
  • Reporting tools for advanced analytics (possibly integrated in future versions)

Third-party service connections

  • Email service for notifications (e.g., SendGrid, Mailgun)
  • Possibly integration with accounting software in future versions

Data exchange protocols

  • RESTful APIs for most integrations
  • Webhook support for real-time notifications (if implemented)

8. Non-Functional Requirements

Performance benchmarks

  • Page load times < 2 seconds
  • API response times < 500ms for 95% of requests

Reliability targets

  • 99.9% uptime for the application
  • Zero data loss for financial transactions

Availability SLAs

  • System available 24/7 with planned maintenance windows communicated in advance

Disaster recovery plan

  • Regular database backups (at least daily)
  • Ability to restore from backups within 2 hours
  • Consideration of multi-region deployment for high availability

This architecture documentation provides a comprehensive overview of the Hafta-Test system based on the available information in the GitHub repository. Some aspects are inferred from common practices in Rails applications and may need adjustment based on specific implementation details not visible in the public repository.
