领域建模 - 对象状态
练习资源:Asg-RH.pdf
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
领域模型
数据库模型
- Hotel (ID/Key, LocationID/FKey, Name, Stars, Address, Introduction, Rating, LowestPrice, IsFavourite, Discount)
- Room (ID/Key, HotelID/FKey, RoomDescriptionID/FKey, Type, Date, Price, IsAvaliable)
- RoomDescription(RoomDescriptionID/key, RoomCatalogID/Fkey, Type, Totals, List-price, description)
- RoomCatalog(ID/key, Type)
- Location (ID/Key, Name, IsFavourite, Code)
- Traveler (ID/Key, Name, Phone, IDCardNum, Email)
- Reservation (ID/Key, TravelerID/FKey, HotelID/FKey, NumOfRoom, TotalPrice)
- ReservationItem (ID/Key, ReservationID/FKey, RoomID/Fkey, Type, CheckInDate, CheckOutDate, Price, NumOfNight, NumOfPerson)
Payment
领域模型
数据库模型
- Payment (ID/Key, TimeStamp, TotalPrice)
- PaymentItem (ID/Key, PaymentID/FKey, ReservationItemID/FKey, Price, Description, CreditCardType)
- CreditCard (ID/Key, UserID/FKey, PaymentID/FKey, CardNumber, Type, SecurityCode, ExpiryDate)
- CreditCardDetail (ID/Key, CreditCardID/FKey, FirstName, LastName, PostCode, CityOrState, Country)
- User(ID/Key, Phone, IDCardNum, Email)
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。
