Project Overview

Objective: Provide a backend for an Airbnb-like service, handling user registration, property listings, bookings, payments, and reviews with scalability and security in mind.

Project Goals:

• User Management: Secure registration, authentication, and profile management.
• Property Management: Create, update, retrieve, and delete property listings.
• Booking System: Mechanism for users to reserve properties with check-in/check-out details.
• Payment Processing: Integrate transactional flows and record payment details.
• Review System: Allow users to leave reviews and ratings.
• Data Optimization: Ensure efficient data retrieval via indexing and caching.

Team Roles

Role	Responsibilities
Backend Developer	Implement RESTful and GraphQL endpoints, business logic, routing, and error handling.
Database Administrator	Design and maintain relational schemas, indexing strategies, and optimize queries.
DevOps Engineer	Configure CI/CD pipelines, containerization (Docker), monitoring, and deployment.
QA Engineer	Write and execute automated tests, validate API contracts, and ensure quality standards.

---

Technology Stack

Technology	Purpose in Project
Django	High-level Python web framework for building RESTful APIs.
Django REST Framework	Toolkit for creating and managing REST endpoints, serialization, and viewsets.
PostgreSQL	Relational database for storing users, properties, bookings, payments, and reviews.
GraphQL	Query language for flexible, efficient data retrieval and manipulation.
Celery	Handle asynchronous tasks (e.g., sending emails, processing payments).
Redis	In-memory store for caching frequently accessed data and session management.
Docker	Containerization for consistent development and deployment environments.
GitHub Actions	Automate CI/CD workflows: testing, building, and deployment.

Database Design

Entities & Relationships:

Entity	Key Fields	Relationships
User	id, name, email, password_hash, role	One user can own multiple properties; can place multiple bookings; can post multiple reviews.
Property	id, title, description, location, price, owner_id	Belongs to one user; can have multiple bookings and reviews.
Booking	id, user_id, property_id, check_in, check_out, status	Belongs to one user and one property.
Payment	id, booking_id, amount, currency, status, created_at	One-to-one with Booking; records transaction details.
Review	id, user_id, property_id, rating, comment, created_at	Belongs to one user and one property.

Entity Relationships:

• User ↔ Property: One-to-Many (a user can list many properties).
• User ↔ Booking: One-to-Many (a user can have many bookings).
• Property ↔ Booking: One-to-Many (a property can be booked multiple times).
• Booking ↔ Payment: One-to-One (each booking has a single payment record).
• User ↔ Review: One-to-Many (a user can post multiple reviews).
• Property ↔ Review: One-to-Many (a property can have multiple reviews).

Feature Breakdown

Feature	Description
User Management	User registration, login/logout, JWT-based authentication, and profile updates.
Property Management	CRUD operations for property listings: hosts can add, modify, and remove listings.
Booking System	Users can reserve properties, view booking history, and manage upcoming reservations.
Payment Processing	Secure processing of booking payments, integration with payment gateway, and transaction logging.
Review System	Users can rate and comment on completed stays to maintain community trust.
API Documentation	Interactive OpenAPI docs for REST endpoints and GraphQL explorer for flexible queries.
Asynchronous Tasks	Email notifications for booking confirmations, reminders, and payment receipts.

API Security

To protect user data and ensure secure transactions, the following measures will be implemented:

• Authentication:

  • JWT tokens stored in HTTP-only cookies.
  • Access & refresh token rotation.

• Authorization:

  • Role-based access control (RBAC) for endpoints (e.g., only owners can modify their listings).

• Data Validation & Sanitization:

  • Input validation at serializer level to prevent injection attacks.

• Rate Limiting:

  • Throttle requests per IP/user to prevent DDoS and brute-force attempts.

• HTTPS Enforcement:

  • Enforce TLS for all API traffic to secure data in transit.

• CSRF Protection:

  • Ensure CSRF tokens on state-changing operations (if cookies are used). |

CI/CD Pipeline

Overview: Continuous Integration and Deployment (CI/CD) automates testing and delivery to ensure rapid, consistent updates.

Key Steps:

1. Build & Lint: Run static analysis (flake8, black) on each PR.
2. Unit & Integration Tests: Execute test suite (pytest) and ensure all tests pass.
3. Docker Build: Build Docker images for backend service.
4. Deploy to Staging: Automatically deploy to a staging environment on merge to main branch.
5. Smoke Tests: Run basic health checks against staging.
6. Production Deployment: Manual approval for production rollout.

Tools:

• GitHub Actions: Define workflows for build, test, and deploy.
• Docker & Docker Compose: Containerize services for local and CI environments.
• Heroku / AWS ECS / Kubernetes: Potential targets for deployment.
