Project background and significance
Purpose : The main goal of this topic is to design and implement a lost and found system based on the WeChat applet. The front-end users use the applet, and the back-end management uses a B/S architecture based on PHP+MySql; through the back-end management information, member management, classification management, Lost and found information management, message management, etc. Users can log in through the mini program to view the latest announcement information on the platform, publish their own lost and found information, etc.
Significance : The lost and found system based on the mini program is a product of the combination of computer technology and lost property management. Through the small program lost and found system, efficient management of lost and found information is achieved. With the continuous improvement of computer technology, computers have penetrated into every corner of social life. However, the method of manually managing and publishing lost property information is not only inefficient, error-prone, cumbersome, but also consumes a lot of manpower. In order to meet the requirements of market managers for lost property information management, announcement information management, and lost property personnel management, on the premise that the management staff have certain computer operation capabilities, this lost property system software based on small programs is specially compiled to improve transaction information. Management efficiency.
Feasibility Analysis
The feasibility of system development can be summarized in the following three aspects of the new student registration system based on the WeChat applet, as follows:
1. Technical feasibility
Use Windows 7 or 10 as the operating system, use phpstorm software as the development backend management, use MySQL for database storage, and use WeChat developer tools to develop WeChat applets; the hardware environment of the backend management system is a PC, and front-end users use WeChat applets on their mobile phones. .
2. Economic feasibility
On the one hand, using phpstorm and WeChat developer tools to develop a good human-machine interface and strong functional support can further improve the efficiency of lost property managers in managing lost and found transaction information, thereby saving manpower and material resources; on the other hand, The production cost of the system is low, and it can be developed on existing PCs using phpstorm and WeChat developer tools.
3. Operational feasibility
The phpstorm software operates on the Windows operating system; the developed backend can be used for lost and found information management, realizing the entry, modification, and deletion of backend information, member information management, deletion, management and deletion of message information, and lost and found information. Information management, deletion, etc. Those who have lost property can use their mobile phones to log in to the WeChat applet lost and found system.
