Ticket purchase record management
1. Project Introduction
Since the development of the Internet, both its theory and technology have matured, and it has widely participated in all aspects of society. It allows information to be disseminated through the Internet, and combined with information management tools, it can provide good services to people. In order to solve the problems of chaotic bus ticketing information management, high error rate, poor information security, high labor intensity, time-consuming and labor-intensive, the bus ticketing website can be used for effective management, making information management more scientific and standardized.
The car ticketing website is coded in the Eclipse environment using Java language and Mysql is used to create a data table to save the data generated by this system. The system can provide information display and corresponding services. Its administrator is responsible for reviewing member recharges, reviewing customer ticket purchase information and member ticket purchase information, managing passenger flights and message boards, and managing membership levels. Customers can check passenger train schedules, purchase and pay tickets, contact customer service at the front desk, leave messages to the administrator, check ticket purchase records in the backend, and recharge memberships. Members purchase tickets through the member ticket purchase channel, pay for tickets in the backend, check the ticket purchase review status, check membership levels, and manage collection information.
In short, the car ticketing website centrally manages information and has many advantages such as strong confidentiality, high efficiency, large storage space, and low cost. It can reduce information management costs and realize computerization of information management.
2. System design
A successfully designed system must be rich in content and user-friendly in terms of system appearance or system functions. Therefore, in order to enhance the value of the system, attract more visitors to the system, and allow visiting users to spend more time on the system, it means that the system is designed to be more professional.
Design Principles
This system needs to follow certain design principles during the design process. The purpose is to ensure that the developed system has high quality, complete functions, and is convenient and simple to operate, so that it can meet the user's requirements to the greatest extent. In addition to the basic principles of easy operation, the system design principles also include the principles of safety and accuracy.
The first design principle: the principle of ease of operation. The functions designed for this system must be complete and complete. When coding, the interfaces designed must be friendly. Once users use this system, they must be able to easily get started and operate the system to process data. time, it must be convenient. In addition, some necessary prompts need to be designed to guide users to operate the system.
The second design principle: the security principle. This system needs to authenticate each visitor in the login module. The system will judge based on the information entered by the visitor, use the security verification code written in advance for data comparison, and guide the successful matching. Visitors enter the specified operation interface. This prevents irrelevant visitors from stealing system data.
The third design principle: the principle of accuracy. In order to ensure that the data registered by users is correct, a data error correction mechanism needs to be designed in advance so that users can carefully check the registered error information through the system's error prompts and correct the errors in a timely manner. , fill in the correct information. For example, when setting a password, it is required that the length of the password cannot be less than 6 characters, and the data type cannot be all numbers, etc. can be standardized.
