made a case diagram 1. Use Case Diagram:The use case diagram would capture the high-level functionalities of the system. Here are afew use cases:• Park vehicle (motorcycle, car, bus)• Unpark vehicle• Get available spots• Reserve spot (could be an extension)

In this question we have to understand and design a use case digram for the given requirement.Let's understand and hope this helps, If you have any queries please utilize threaded question feature.In the diagram, there would be:Driver representing the person operating the vehicle.Operator representing the person responsible for managing the parking deck.System representing the parking deck system itself.Diagram:Use cases are represented in ovals, and actors are represented as stick figures. Park Vehicle: This use case allows the driver to park a vehicle, which can be a motorcycle, car, or bus.Unpark Vehicle: This use case allows the driver to unpark a vehicle when leaving the parking deck.Get Available Spots: This use case allows the driver to check for available parking spots in the deck.Reserve Spot: This use case, which could be an extension of "Park Vehicle," allows the driver to reserve a parking spot. This use case is associated with the system.Actors (Driver and Operator) can interact with these use cases, indicating the high-level functionalities that each type of user can perform. The associations between use cases and the extension relationship between "Reserve Spot" and "Park Vehicle" are also shown.This use case diagram provides an overview of the system's main functionalities and the roles of the actors involved in parking and managing vehicles in the parking deck.
