1. Understand the Project Goals:

Create an efficient, user-friendly, and scalable parking lot system to accommodate various vehicles, ensure quick vehicle retrieval, and secure payment handling.

2. Requirements:

Functional:

• Vehicle identification via license plate recognition.
• User account verification for regular customers.
• Real-time tracking of vehicle locations and durations.
• Efficient vehicle retrieval for quick exits.
• User registration and vehicle association.
• Real-time availability of parking spots.
• Spot allocation based on vehicle size and user preferences.
• Payment processing integration.

Non-Functional:

• Scalability for at least 1,000 parking spots.
• 99.9% uptime for high availability.
• Redundancy and failover for reliability.

3. System Components:

Microservices:

• User Service:
  • User Registration: Implements an endpoint to accept user details and create new accounts. It stores user information securely and provides unique identifiers for each user.
  • Login and Authentication: Offers secure authentication mechanisms, such as OAuth 2.0, and generates tokens for session management.
• Vehicle Service:
  • Vehicle Data Management: Registers vehicles to user accounts and stores details like make, model, and tier preferences. It also assigns a unique vehicle ID for tracking within the system.
