Lecture 3

Question

Find candidates for structural relations between the classes in your event table - do this pair by pair

classDiagram

    class carRental {
        String name
        String age
        String carType
    }

    class Reservation {
        String reservationID
        Date startDate
        Date endDate
        cancelReservation()
    }

    class Person {
        String name
        String age

    }

    class LeaseAgreement {
        String leaseID
        Date startDate
        Date endDate
        String insuranceType
        float deposit
        finalizeLease()
    }

    class Customer {
        Boolean goodCustomer
        string driversLicense
        reserve()
        receiveGift()
    }

    class privateCustomer {
        Date rentalDate
    }

    class BusinessCustomer {
        String businessName
        String taxID

    }

    class Car {
        String model
        String type
        getStatus()
        needsMaintnance()
    }

    class Employee {
        Float Salary
        fire()
        giveGift(Customer)
    }






    BusinessCustomer <|-- Customer : Inherits
    privateCustomer <|-- Customer : Inherits
    Customer <|-- Person : Inherits
    Employee <|-- Person : Inherits
    LeaseAgreement <..> Customer : Relation
    LeaseAgreement <..> Car : Relation
    Reservation <..> Customer : Relation

Question

Explore if any of the patterns are relevant to your case - do this for each class

Class Name	Description
carRental
Customer	Hierarchy
privateCustomer	Hierarchy
BusinessCustomer	Hierarchy
Car
Employee	Hierarchy
Reservation
LeaseAgreement
person	Hierarchy, roles

Question

Make a class diagram

See question 1!

Question

Look for opportunities to simplify and extend the class diagram

incorporate roles

    class carRental {
        String name
        String age
        String carType
    }

    class Reservation {
        String reservationID
        Date startDate
        Date endDate

    }

    class Person {

    }

    class LeaseAgreement {

        Date endDate
        String insuranceType
        float deposit

    class Customer {
        Boolean goodCustomer

    class Car {

        needsMaintnance()
    }

    class Employee {
        Float Salary
        fire()
        giveGift(Customer)
    }

    class Roles {

    }

    class privateCustomer {
        Date rentalDate
    }

    class BusinessCustomer {
        String businessName
        String taxID

    }







    Roles <|-- Employee
    Roles <|-- Customer
    Person <|-- Roles
    BusinessCustomer --|> Customer : Inherits
    privateCustomer --|> Customer : Inherits
    LeaseAgreement --> Customer
