A project written a few months ago, through this project, you can learn about database triggers, the basic syntax of python, the use of some third-party libraries in python, including how python connects the front and back ends (interface and data) , as well as interface design and so on. I hope you can learn something from the project.
1. Project Background
1. Brief description of experimental design
The hotel management system establishes the system by providing the relationship between customer and employee information, including employee management functions, rental management functions, customer management functions, order management functions, report and maintenance functions, and login functions. The system can quickly find the customer's room information by searching the customer information. It also includes the addition, deletion, modification, and query of customer information and the addition, deletion, modification, and query of employee information
.
(2) The hotel has rooms of various standards. Room data includes room number, room class, room price and room status (whether there are already guests). The room number uniquely represents a room, and the room level determines the price of the room. There are various levels of rooms, including single rooms, standard rooms, deluxe rooms, business rooms, and executive rooms. The room status indicates whether the room can be booked, checked in or transferred.
Basic function realization:
(1) Room management.
(2) Management of guest room reservation and cancellation.
(3) Guest check-in and in-store consumption management.
(4) Settlement management.
(5) Realize classification query.
(6) Output the corresponding datagram
Describe the main functions of each business.
1. Room management: store room information data, room number, customers can check the room type (single room, standard room, deluxe room, business room, executive room), room price, room status (with or without guests, no guests: the room can be reserved , the room can be transferred in. There are guests: the guest can check out and transfer), and the room corresponds to the floor.
2. Customer management: Customers are divided into individual reservation customers and team reservation customers (reservation time, reservation customer number), individual check-in customers and team check-in customers (check-in time, check-in customer number), and room change function.
3. Employee management: You can add employees (name, gender, employee number, position, entry time), delete employees, modify employees, and query employee information. You can view all orders, add, delete, and modify rooms (room number, room type, price).
4. Reports and maintenance: data backup (export data, import data, export data tables to tables), reports.
5. Order management function: order record report, room type (picture description), payment amount, customer information (customer number, check-in time, check-out time) 6. Login function: login (staff (account password)
login /Customer (account password) login) password retrieval function, password modification function.
2. Analyze and list the data items involved according to the function.
- booking_client personal reservation form: (cid customer number, rid room number, star_time check-in time, end_time check-out time, booking_time reservation time, remark note)
- booking_team team booking form: (tid team number, rid room number, star_time check-in time, end_time check-out time, booking_time booking time, remark note)

Data security refers to protecting digital information from unauthorized access and resisting risks such as damage and theft during the entire life cycle of digital information. To this end, we have set up permission access, and only the correct account password can be viewed For related information, non-administrator logins cannot obtain system information. In addition, we can also view the corresponding data reports and customer employee personal information through the input account password matching, or modify the data that needs to be changed. This also makes it difficult for information to be leaked out, increasing the modifiability of data. In order to prevent the administrator from wanting to change the password, we have also set up the function of changing the password on the login page, which strengthens the security of the data. In order to prevent problems such as loss of original data caused by human error, data loss caused by software bugs, and database data loss caused by hardware failures, we have set up database backups to retrieve lost data information. Especially the customer's reservation information, check-in information and data report information, our database will be updated every time a new customer or group is added, which is also conducive to our data verification. Using database backups also facilitates the use of the same database for new environment setups and development and test environment database setups. From the perspectives of data security, data backup and others, describe the security policies and risk control policies that the system can adopt

Third, the creation of the database
There are too many pictures, and it would be too much space to post them all. If you want to see them, just like, bookmark and follow, and then private message me in the background.
Four, GUI interface presentation
It's the same, I didn't show all the interface, but only a part of it. If you want to see the follow-up, just like, bookmark and follow, and then private message me in the background.
1. Modify password interface
2. View personal information, employees can log in to view
3. Add employees and fill in their basic information
4. Query room information
5. Query report: occupancy rate and order volume, as well as relevant information of customers and employees
6. Database risk prevention measures: data backup, and generate the backup file on the computer
7. The main interface of the hotel management system
Five, the code file
If you need the source code, please like, collect and follow, and then private message me in the background! ! !
