使用 UMLet 建模

1、使用类图,分别对 Asg_RH 文档中 Make Reservation 用例以及 Payment 用例开展领域建模。然后,根据上述模型,给出建议的数据表以及主要字段,特别是主键和外键

  • 注意事项:

    • 对象必须是名词、特别是技术名词、报表、描述类的处理;
    • 关联必须有多重性、部分有名称与导航方向
    • 属性要注意计算字段
  • 数据建模,为了简化描述仅需要给出表清单,例如:

    • Hotel(ID/Key,Name,LoctionID/Fkey,Address…..)

Make Reservation

  • Hotel (ID/Key, name, address, cityID/Fkey)
  • City (ID/Key, name)
  • Room (ID/Key, type, availability, hotelID/Fkey)
  • Customer (ID/Key, fullName, emailAddress)
  • ReservationItem (ID/Key, roomID/Fkey, basketID/Fkey, checkInDate, checkOutDate, adultNum, childrenNum, price, isSmoking)
  • ReservationBasket (ID/Key, customerID/Fkey)

Payment

  • Payment (ID/Key, totalPrice)
  • PaymentWithCard (ID/Key, paymentID/Fkey, creditCardNum/Fkey)
  • CreditCard (CardNum/Key, type, securityCode, expiryDate, cardHolderAddressID/Fkey)
  • CardHolderAddress (ID/Key, title, firstName, lastName, address1, address2, city, countyOrState, country, postcode, daytimeTelephone, eveningTelephone)
  • ReservationItem (ID/Key, paymentID/Fkey, roomID/Fkey, basketID/Fkey, checkInDate, checkOutDate, adultNum, childrenNum, price, isSmoking)

2、使用 UML State Model,对每个订单对象生命周期建模

  • 建模对象: 参考 Asg_RH 文档, 对 Reservation/Order 对象建模。
  • 建模要求: 参考练习不能提供足够信息帮助你对订单对象建模,请参考现在 定旅馆 的旅游网站,尽可能分析围绕订单发生的各种情况,直到订单通过销售事件(柜台销售)结束订单。
