How to develop a simple logistics management system using Go language

With the rise of e-commerce, the logistics industry is developing rapidly. In order to improve logistics transportation efficiency, optimize distribution processes and reduce costs, many logistics companies have begun to use information technology for management and operations. In this article, we will introduce how to develop a simple logistics management system using Go language.

1. System requirements analysis
Before starting to develop the logistics management system, we first need to clarify the basic requirements of the system. A simple logistics management system should include the following functions:

1. Express order management: including functions such as entry, query, modification and deletion of express orders.
2. Order management: including functions such as order generation, allocation, modification and cancellation.
3. Vehicle management: including functions such as vehicle entry, dispatching and maintenance.
4. Driver management: including functions such as driver entry, shift scheduling and attendance.
5. Route planning: Automatically calculate the optimal delivery route.
6. Data statistics: including express delivery volume statistics, transportation cost statistics and other functions.
7. User permissions management: including permission settings for different user roles.

2. Technology selection
In the process of developing the logistics management system, we chose to use Go language as the development language. Go language is a simple, efficient and reliable language with good concurrency performance and easy maintenance. Additionally, we will also use the MySQL database to store system data.

3. System architecture design
Before starting coding, we need to design the system architecture. We chose to use the MVC (Model-View-Controller) design pattern to organize the code. Among them, the controller is responsible for processing user requests and corresponding business logic processing, the model is responsible for processing data and business logic, and the view is responsible for displaying data to users.

4. Database design
When designing the database, we need to design the corresponding data table according to the system requirements. According to the functions of the logistics management system, we can design the following tables:

1. User table: stores user information, including user name, password, permissions, etc.
2. Express order table: stores express order information, including express order number, consignor, consignee, etc.
3. Order table: stores order information, including order number, product information, shipping address, etc.
4. Vehicle table: stores vehicle information, including license plate number, model, load, etc.
5. Driver table: stores driver information, including name, mobile phone number, etc.

5. Coding Implementation
Before starting to write code, we need to install the Go language development environment and the corresponding database driver. Next, we can write the code step by step according to the system requirements. During the coding process, we need to pay attention to the readability, maintainability and testability of the code.

6. Testing and debugging
In the process of writing code, we need to test and debug to ensure that each function of the system operates normally. We can use the unit testing framework of the Go language for unit testing, and use tools such as Postman for interface testing.

7. Deployment and Online
After completing development and testing, we can deploy the code to the server and go online. During the deployment process, we need to pay attention to the configuration and security of the server.

8. Summary
By using the Go language to develop a simple logistics management system, we can improve the efficiency and accuracy of logistics and transportation, and achieve real-time tracking of orders and transparency of distribution information. Of course, this is just a simple logistics management system. If more complex functions are required, it can be expanded and optimized according to actual needs.

In short, the Go language has the characteristics of high performance, high reliability and easy maintenance, and is very suitable for developing logistics management systems. I hope this article will be helpful to you in the process of developing logistics management system using Go language.
