2. Project introduction
2.1 Basic introduction
The rapid development of e-commerce has also led to the prosperity of China's express delivery and logistics industry. Online shopping and receiving express delivery seem to have become a small joy in people's daily life. Regarding the management of courier information, there are many software and platform systems built by courier companies in the market. For example, Alipay can query the courier information based on the logistics distribution of Cainiao Network, but it cannot query the courier packages that do not pass through Cainiao Network. Similarly, the courier information of courier companies such as STO Express and Shunfeng Express is also closed-loop query. If a customer purchases express delivered through different express platforms, it is very inconvenient to log in to multiple platforms to view the delivery information of the express. The express transportation management system based on the WeChat applet to be studied in this topic is to solve this problem.
This set of express transportation management system based on the WeChat mini-program developed after research is mainly based on the lightweight client application of the WeChat mini-program to realize information query and management. Consumers can register and log in to the WeChat mini-program platform. Complete information query, express information query, delivery information query, etc., the express delivery staff can log in to complete the delivery of express information, query and other operations, and at the same time, the background administrator can log in to perform corresponding management operations on the information of the entire express platform.
In terms of technology selection, the express transportation management system developed by this topic uses WeChat applet development tools to implement the front-end, and combines the VUE framework to use Nodejs to run the front-end project of the background management. The background service interface is integrated and developed using the SSM framework. The database uses MYSQL5.7 database for data storage and data relationship design. The whole system is developed and implemented by separating the front and back ends, and the human-computer interaction is in line with people's daily habits.
2.2 Demand Analysis
Based on the survey of express delivery stations and the survey and analysis of users who often shop online, it is known that the user roles of this system are divided into three categories, namely ordinary users, delivery personnel and system administrators. The following describes the functional operation of this user.
The main functional operation examples of ordinary users are shown in the figure below:
Figure 3-1 Common user use case diagram
Ordinary users mainly have the functions of online registration and login, platform announcement information query, personal courier information viewing, delivery information viewing, personal center management, etc.
The use case diagram for the function realization of the courier user is shown in Figure 3-2 below.
Figure 3-2 Use case diagram of delivery staff
The delivery staff registers and logs in to the front end of the WeChat applet, and can browse the announcement information online, check the express delivery that needs to be delivered and pick it up. After the offline delivery is completed, modify the delivery status and wait for the customer to confirm.
The functional use case diagram of the platform administrator is shown in Figure 3-3 below.
Figure 3-3 Administrator use case diagram
The platform administrator of the express transportation management system can manage the information of users and delivery personnel registered at the front end after logging in to the system, and at the same time manage the carousel image information and personal information released by the front end. In the user management module, you can add the courier information owned by this user. After adding, both the WeChat applet user and the courier can view it. At the same time, the administrator can manage the added courier information in the courier information management module. In the delivery information management The module manages the courier information that has been received by the courier, manages the delivered courier in the delivery courier module, and manages the completed courier information in the confirmation completion management module.
2.3 Database design
According to the above extraction and description of the database entity information, the specific table structure information is analyzed. If a professional UML tool is used for design, the specific table structure can be directly generated according to the entity diagram. The main table structure information of the system is shown below.
