Question

 IN C.

This is a hotel room and guest management system, the main purpose of this procedure is to manage the room, manage the guest account and check the hotel performance (how many rooms are booked, etc.). There are two types of people who use this system, the manager and the receptionist.

As a manager, there are three options:

1. Set/adjust room levels and rates for each level

Detail: there are 80 rooms in the hotel, 10 on each floor, eight floors. All rooms have four levels: **, ***, *** and VIP. I think the operation here is that the manager can manually input a room number, and then divide it into one of the four levels. Each level has a fixed price.

2. Manage customer information (add/adjust/delete)

Detail:The manager will be able to see a library of users and (add/remove/modify) the customer in it, as well as label some users with special VIP codes that will allow them to stay in VIP rooms.

3. Check hotel status

Detail: this means that the manager can see how many people have stayed in the hotel, if the most simplified, is the room occupancy rate.
