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

• Travellers(ID/key,name,email-address)
• Reservation(ID/key,TravellersID/Fkey,date,time,number of nights)
• Hotel(ID/key,Loc-code/Fkey,name,stars,address,brief-intr,favourites,low-price,rating,max-discount)
• Reservation Item(ID/key,HotelID/Fkey,type,check in date, number of nights,number of adults,number of children)
• Room(ID/key,HotelID/Fkey,ReservationItemID/Fkey,type,date,isAvailable,price)
• RoomDescription(ID/key,RoomID/Fkey,type,total,list-Price,description)
  
• Travellers(ID/key,name,email-address)
• Reservation(ID/key,TravellersID/Fkey,date,time,number of nights)
• CreditCard(ID/key,TravellersID/Fkey,type)
• CardDetails(ID/key,CreditCardID/Fkey,number,securityCode,expiryDate)
• Payment(ID/key,ReservationID/Fkey,date,time,total)

2、使用 UML State Model，对每个订单对象生命周期建模
