The main users of the train booking management system are divided into administrators and users. The functions include administrators: home page, personal center, user management, model information management, train information management, ticket order management, change order management, and refund order. Management, system management, user: home page, personal center, ticket order management, change order management, refund order management, front page home page; home page, train information, train information, personal center, background management and other functions.
Database Design
A good database can be related to the pros and cons of program development. Database design is inseparable from the design of table structure, as well as the relationship between tables, as well as information such as the content of data tables that need to be designed for system development. During the database design, it is necessary to carry out targeted development and design of the database according to the actual situation.
Database ER diagram design
This train booking management system uses MYSQL database, which is fast in data storage, because the train booking management system is mainly about the management of information, and there is a lot of information content, which requires a good database to be well designed, and the classification must be clear , when the information cannot be added, the information is too confusing. The designed database first needs to express the relationship between the various entities clearly. The ER diagram of the system is shown in the following figure:
1. User information entity diagram is shown in the figure
2. The entity diagram of train information management is shown in the figure
3. The entity diagram of model information management is shown in the figure
System detailed design
Front page home function module
In the train booking management system, you can view the home page, train information, train information, personal center, background management, etc. on the home page of the system, as shown in the figure
Login, user registration, on the user registration page, you can fill in the user name, password, name, gender, avatar, ID card, mobile phone and other information to register, as shown in the figure
Train information, fill in the train name, train name, license plate, picture, starting station, terminal station, route, date, departure time, duration, seat type, price, number of tickets and other information on the train information page. As shown
