Design Parking Lot System

Functional Requirements:

• Users can check for available parking spots in a parking lot.
• Users can reserve a parking spot for a specific time period.
• Users can park their vehicle in the reserved spot.
• Users can check out (leave) and release the spot.
• The system must prevent double-booking of parking spots.

Non-Functional Requirements:

• The system should be consistent, ensuring that no two users can reserve the same spot for overlapping times.
• The system should be available and responsive to user requests.
• The system should be able to support multiple parking lots, each with multiple spots.
• The design should be simple and easy to extend for future features (e.g., support for different vehicle types).

Out of Scope:

• Payment processing and integration with third-party payment providers.
• Support for different parking spot types (e.g., electric vehicle charging, handicapped spots).
• Advanced features like dynamic pricing, user reviews, or loyalty programs.
