The development of the Internet has unlimited prospects. Early integration with the Internet, synchronization with the information age, and integration with high technology will surely inject fresh vitality into the development of all walks of life in society. Standing on the eve of the Internet age, we clearly heard the declaration of the Internet age: whoever controls the Internet controls the future. With the advancement of the times, information technology continues to develop. With the continuous research and development of mankind, the Internet era has arrived. People's consumption level is also constantly improving. Vehicle maintenance has slowly entered people's lives from scratch and developed rapidly, becoming a new type of consumption. This system is divided into four roles for login management: user, maintenance worker, merchant, and administrator. The four are interrelated. The user creates a fault repair order, the merchant accepts the car repair order, and the order is dispatched to the repairman. While ensuring the interests of all three parties, it also leads the trend of new industries.
Taking into account the fitness needs in real life and careful analysis of the system, the vehicle fault management system permissions are divided into administrators, maintenance personnel, merchants, and users.
According to the current situation, I designed a vehicle fault maintenance system with network functions. Customers can check the relevant vehicle maintenance status through the network, and the company's managers can manage it according to the actual situation of the customer. It has strong practicality, that is, It is convenient and improves work efficiency. [1]
As a part of computer applications, using computers to manage various types of information has advantages that manual management cannot match. It improves the labor quality of vehicle failure maintenance managers and shortens the time for customers to view information.
Language: Python
Framework: django/flask
Software version: python3.7.7
Database: mysql
Database tool: Navicat
Front-end framework: vue.js
By comparing two frameworks with different factors, it can be seen that Flask and Django cannot be labeled as being in a single function Best framework. While Django looks better and offers more features in large, fast-growing projects, Flask seems easier to get started with. Both frameworks are very useful for developing web applications and they should be selected based on the current needs and the size of the project.
The latest python web framework django/flask can be developed. Based on B/S mode, front-end technology: nodejs+vue+Elementui+html+css
, front-end and back-end separation is to split a single application into two independent applications: front-end Applications and back-end applications use JSON format for data interaction. This fully ensures the system code's good readability, practicality, easy scalability, versatility, and easy later maintenance.
With the continuous improvement of science and technology, computer science has become increasingly mature. Its powerful functions have been deeply understood by people, and it has entered various fields of human society and plays an increasingly important role. With the rapid development of the vehicle maintenance industry in our country, the business volume is also increasing, and the requirements for information processing are also getting higher and higher. The traditional automobile management personnel can no longer meet the needs of the vehicle maintenance business, so I will use calculations The rational utilization of resources such as huge storage space, high-performance processing, highly reliable data security, and clear visual data can truly achieve the purpose of reducing labor and improving labor quality.
