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

数据表清单:

  • Customer (ID/Key, name, emailAddress)
  • Hotel (ID/Key, LocationID/FKey, name, address, info, favourites, lowest-prices, star-rating, cut-off)
  • Location(ID/Key, name)
  • RoomType(ID/Key, name)
  • RoomDescription(ID/Key, HotelID/FKey, type, list-prices, info, list-services)
  • Room (ID/Key, RoomDescriptionID/FKey, type, date, price, isAvailable, availableNum, reservedNum)
  • Reservation (ID/Key, CustomerID/FKey, HotelID/FKey, checkInDate, numberofNights, checkOutDate, total, IsCustomerSmoking, contactEmail)
  • ReservationItem (ID/Key, ReservationID/FKey, RoomID/Fkey, adultsNum, childrenNum, childrenAges, numberofNights)

Payment

数据表清单:

  • Payment(ID/Key, CreditCardID/FKey, date, time, total)
  • PaymentItem(ID/Key, PaymentID/FKey, details, price)
  • Customer(ID/Key, name, emailAddress)
  • CreditCard(ID/Key, CustomerID/FKey, type)
  • CreditCardDetails(CreditCardID/FKey, number, securityCode, expiryDate)

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。
