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.
