s of ChainHotel Management System: (1) Traveler: can search for the map position of the hotel by accessing to the Inter, make hotel reservation, register as a member, and check integral (2) Hotel administrator: tasks include maintenance of staff information, inquiry (enquiry BRE) the rates of checkin, check all kinds of report forms (3) Receptionist: in charge of checkin and checkout, inquiry information of customers, maintain the type and information of hotel room, inquiry information of guest rooms (4) System administrator: maintain the system data, add, delete or update all the information of guest rooms, members of ChainHotel, and revise preferential activities of members. Features of Software Products Features of this system description: inquiry map position, reservation, management of checkin and checkout, charges system. Reservation contains online reservation and phone reservation.

Scheduled to management use case diagram Customers can search for the map position of the hotel, make sure if there is any vacant rooms, fill in the required information of reservation before they make an online reservation。 it also can be the logic involving in several use cases. Sequence diagram belongs to some interaction among behavioral classifier. Classifier is collaboration. One collaboration can involve several interactions。 at the same time, UML modeling capabilities provide all the process of software development. 1. Portal. UML Unified Modeling Practical Guide.
