Object Oriented Analysis Systems

Creating a complete class diagram for the "Housekeeper service system" if given you an overview of the classes, attributes, and associations you would need:

1. *User*
   - Attributes: name, password, mobile phone, email
   - Methods: updatePassword(), updateMobilePhone()

2. *System Administrator*
   - Inherits from User
   - Attributes: level Of Access
   - Methods: registerWorker(), registerCustomer(), updateServices(), addOffers()

3. *Worker*
   - Attributes: age, nationality, specialty, evaluation degree
   - Methods: displayAssignedVisits(), submitLeaveOfAbsence()

4. *Customer*
   - Inherits from User
   - Attributes: nationality ID, addresses
   - Methods: selectServices(), chooseVisitTime(), confirmServiceInformation(), makePayment(), getTransactionInformation()

5. *Address*
   - Attributes: street name, building number, zip code, city
   - Methods: addAddress(), deleteAddress(), updateAddress(), setDefaultAddress()

6. *Payment*
   - Attributes: transaction ID, date, time, type (Apple Pay, Credit card, bank transfer)

7. *Service*
   - Attributes: contract ID, service type, frequency, start date, end date, period time, number of visits, location, cost in SR
   - Methods: bookService(), selectService(), cancelService(), getServiceInformation()

8. *Visit*
   - Attributes: visit ID, date, address
   - Methods: rescheduleVisit(), changeVisitAddress(), evaluateWorker(), cancelVisit()

9. *VisitWorker*
   - Attributes: worker ID
   - Association with Visit: Many-to-One (Many VisitWorkers to One Visit)

10. *CustomerService*
    - Attributes: services
    - Association with Customer: Many-to-Many (Many Customers to Many CustomerServices)

11. *ServiceVisit*
    - Attributes: visits
    - Association with Service: One-to-Many (One Service to Many ServiceVisits)

12. *ServiceAddress*
    - Attributes: address
    - Association with Service: One-to-Many (One Service to Many ServiceAddresses)

Please note that you would need to add multiplicities and association names to the diagram, specifying whether associations are one-to-one, one-to-many, or many-to-many as per your system's requirements. Additionally, the diagram should show inheritance relationships between classes as mentioned in the problem statement. This is a simplified representation, and you can further refine it based on your specific needs and constraints.
