【正文】 pictured as Figure 2. Fig. 2. Intended use case diagram 13 After the customer logs in the interface of reservation, if he is the member of the hotel would be asked to input the member number and password, then the system will provide his information immediately. The select region and time are the two necessary use cases to ensure the following reservation operation. Namely, the online reservation includes select region, select time and member registration use case, and make use of the use case of room inquiry to check the function. Fig. 3. Intended use case diagram 14 Extensive Referring Use Case Interaction View A collaboration diagram shows the objects and relationships involved in an interaction. Fig. 4. Scheduled interactive diagram Extensive Referring Use Case Active View Active diagram is the control flow that describes a range of activities of system and business, which demonstrates the whole process that transfers one activity to another. Active diagram is a special state machine, which contains most parts of active state, most transformation are triggered by the pletion of the original state activity. The elements of the active diagram consist of operating state, active state, transformation, branch, fork, connection, and track and object flow. Operating state indicates executable and inseparable action execution. For example, to calculate assignment of attribution, invoke an object, send a signal to the object, or build and damage an object, and so on. While active state is opposite to the active state, it can be deposed. Operating state is an exception from the active state for it can’t be deposed furthermore. 15 Active diagram provides the description of system after the use case diagram, to explain more about the execution process of system, and how to change the direction of execution in various situations. Therefore, active diagram is used to build work control flow for the use case model, to elaborate the use case model. Fig. 5. Scheduled activity diagram Extensive Referring Use Case—Sequence View Sequence diagram models use adopted logical proposal, the adopted proposal can be a part of use case。 however, one interaction can only involve one sequence diagram. This is the reservation sequence diagram of the ChainHotel Reservation Management: 16 Fig. 6. Scheduled sequence diagram 4 Feature Requirement In order to ensure the lasting, safe, stable, reliable and effective operation, “ChainHotel Management System” should meet the following aspects of feature requirement. Data Definition System of data processing accuracy and precision requirements shall be satisfied as follows: a) As the input generated by the system must meet 18. b) Required item must have signs, and address which input must conform to the form of address. c) Integer number should be retained on the units. d) The Real data do not special requirement generally retained after the decimal point two.. Characteristics of the Time and Adaptability System processing accuracy and timeliness is the system performance necessary. In the system design and development process, Must fully consider what will the system be exposed to current and future workload, The system3
