List Possible Objects In The New Bike Shop System

List possible objects in the new bike shop system, including their attributes and methods

The bike shop system encompasses several core objects, each representing key entities within the business operations. The primary objects include Customer, Employee, Bike, ServiceRequest, and Inventory. Each object possesses specific attributes that describe their characteristics and methods that define their functionalities within the system.

Customer: Attributes include CustomerID, Name, ContactInformation, Address, and PurchaseHistory. Methods involve Register(), UpdateDetails(), MakePurchase(), and RequestService(). These methods facilitate customer registration, updating personal information, purchasing bikes or accessories, and requesting repairs or maintenance services.

Employee: Attributes encompass EmployeeID, Name, Role, Schedule, and Compensation. Methods include AssignTask(), RecordWorkHours(), ProcessPayment(), and GenerateReport(). Employees can be sales associates, mechanics, or administrative staff, with methods enabling task assignment, time tracking, payroll processing, and report generation.

Bike: Attributes consist of BikeID, Model, Brand, Type (e.g., cruiser, racing), Price, and Status (available, sold, in service). Methods involve UpdateStatus(), RecordSale(), and MaintenanceCheck(). The system manages inventory status and records sales or repairs associated with each bike.

ServiceRequest: Attributes include RequestID, CustomerID, BikeID, ServiceDescription, DateRequested, and Status (pending, in progress, completed). Methods are CreateRequest(), UpdateStatus(), AssignTechnician(), and CloseRequest(), enabling tracking and management of customer service activities.

Inventory: Attributes include InventoryID, PartName, PartNumber, QuantityAvailable, and Supplier. Methods involve AddPart(), RemovePart(), UpdateQuantity(), and GenerateInventoryReport(), assisting in inventory control and procurement management.

Identify at least three possible use cases and two actors

Use Cases:

1. Register Customer: A customer provides personal details to register in the system. Actor: Customer.
2. Process Bike Sale: A sales associate records a new bike sale, updates inventory, and generates a receipt. Actor: Sales Representative.
3. Handle Service Request: A service request is initiated by a customer, assigned to a mechanic, and marked as completed. Actor: Customer and Mechanic.

Actors:

1. Customer – interacts with the system to browse bikes, request services, and make purchases.
2. Sales Representative – manages sales transactions and customer information.

Create a use case diagram that shows how service requests are handled

The use case diagram illustrates the interaction between the Customer, Service Department, and Technician in handling service requests. The Customer initiates a service request, which is recorded by the system. The request is then assigned to a Technician (Mechanic), who performs the repair or maintenance. Upon completion, the request status is updated to 'completed,' and the customer is notified.

Create a state transition diagram that describes typical customer states and how they change based on specific actions and events

The customer lifecycle begins with a 'New Customer' state. When the customer makes their first purchase, their state transitions to 'Active Customer.' If the customer requests service, their state shifts to 'Service Requested.' After the service is completed, the state reverts to 'Active Customer.' If the customer ceases business or is inactive for an extended period, their status may change to 'Inactive Customer.' Actions such as making a purchase, requesting service, or closing the account trigger these transitions.

Sample Paper For Above instruction

The design and implementation of a computer system for Campus Bikes, a bicycle shop situated near a university, require careful consideration of various objects, use cases, actors, and state transitions. This system aims to streamline business operations, improve customer service, and enhance inventory management, aligning with modern standards of retail technology.

Objects in the System

Fundamentally, an object-oriented approach involves identifying entities that encapsulate both data and operations pertinent to their functions. In the context of Campus Bikes, the key objects include Customer, Employee, Bike, ServiceRequest, and Inventory. Each object carries specific attributes; for example, Customer holds details such as CustomerID, Name, and ContactInformation, while Bike comprises attributes like BikeID, Model, and Status. Methods associated with these objects facilitate interactions; for instance, Customer objects can execute Register() or MakePurchase(), and ServiceRequest objects can execute CreateRequest() or UpdateStatus(). These methods encapsulate behaviors like creating new customer profiles, processing sales, or tracking repairs, thereby mirroring real-world business activities.

Use Cases and Actors

Among the critical functionalities are registering new customers, processing bike sales, and managing service requests. Three use cases illustrating system operations include: (1) Register Customer—where a new customer’s details are entered; (2) Process Bike Sale—where a bike is sold, inventory updated, and receipts generated; and (3) Handle Service Request—involving request creation, technician assignment, and completion. Actors facilitating these use cases encompass Customer, who initiates requests and purchases; Sales Representative, who processes sales; and Mechanic or Technician, who performs repairs and services.

Use Case Diagram

The use case diagram visualizes interactions where a Customer initiates a Service Request, which is recorded and assigned to a Technician. The diagram emphasizes the workflow from customer request to service completion, showing the system’s role in managing these activities efficiently.

Customer State Transition Diagram

The customer’s lifecycle can be represented via a state transition diagram, starting with the 'New Customer' state. When a customer makes their first purchase, they transition to 'Active Customer.' If they request service, they move to 'Service Requested.' Once the service is completed, they return to 'Active Customer.' For prolonged inactivity, their status can become 'Inactive Customer.' These transitions are triggered by actions such as purchases, service requests, or account deactivation, accurately reflecting customer engagement patterns.

In summary, developing an effective computer system for Campus Bikes involves understanding the core objects, their interactions through use cases, and the customer lifecycle. An object-oriented approach ensures clarity, modularity, and scalability, providing a robust foundation for the shop’s digital transformation. Such a system would not only improve operational efficiency but also enhance customer satisfaction by streamlining sales, service, and inventory management activities.
