Go language and MySQL database: How to divide data roles?

In modern software development, data role division is a very important part. It touches on all the critical aspects involved in software development such as security, data integrity, and user management. In this article, we will discuss how to use Go language and MySQL database for data role partitioning.

What is data role division?

Data role classification is the process of dividing data into different categories, each category corresponding to a specific user role. These user roles can be employees in different departments, users with different access rights, administrators, or other types of users.

Data role division can ensure that each user can only access the data they have permission to access. It can also make software development more secure and maintainable.

Using MySQL database for data role division

MySQL is a popular relational database that provides some functions that allow us to divide data into roles.

The following are the three main user roles in MySQL:

1. Administrator

The administrator has all permissions to access the entire database, including creating and deleting databases, Create and delete tables, view data in tables, maintain data, etc.

2. Ordinary users

Ordinary users are restricted from accessing part of the database. They can insert, update, and delete data within the scope of their permissions, but they cannot modify the entire database.

3. Read-only user

This type of user can only read the database and cannot make any changes. They can view stored data, but cannot create, update, or delete any part of the database.

Use Go language to implement data role allocation

Go language is a simple and easy-to-use programming language that can easily integrate the data role allocation function into the code.

The following is a simple example implemented using Go language:

func getUserRole(userId string) string {
   //获取用户角色的代码逻辑，在这个例子中，我们使用MySQL数据库查询实现

   //如果用户是管理员，则返回"admin"
   //如果用户只是普通用户，则返回"user"
   //如果用户是只读用户，则返回"read_only"

   return "unknown"
}

In this example, the function "getUserRole" obtains a user id and retrieves the user role from the MySQL database based on the user id. . If the user is an administrator, it returns "admin", if it is an ordinary user, it returns "user", if it is a read-only user, it returns "read_only". Coupled with the user role function of the MySQL database, we can easily make our software only provide appropriate access rights to the appropriate users.

Summary

It is very important to integrate data role division into software development to ensure access control and data security. MySQL database provides user role functions that can help us achieve this goal. At the same time, the Go language also provides a simple and easy-to-use programming method, which can integrate this function into our code to achieve better data management.
