How to design a system that supports multiple users of schools or institutions in online answering questions

With the development of technology, more and more schools and institutions are beginning to adopt online Question-answering system to improve teaching effectiveness and learning efficiency. When designing an online question-answering system that supports multiple users, we need to consider the following aspects: user management, question management, exam management, question-answer management, and system security.

First of all, the user management module is the core of the entire system. We need to design a user registration and login interface to support multiple users to log in and answer questions at the same time. Each user needs a unique username and password, and needs to select the school or institution to which they belong. In the user management module, we also need to design a user rights management function, including different role rights for administrators, teachers, and students.

Secondly, the question management module is the basis for users to answer questions. We need to design a question bank management interface to support administrators or teachers to add, modify and delete questions. Each question needs to have a unique question ID and corresponding information such as question content, options, and correct answers. Questions can be managed according to subject, chapter, difficulty, etc., making it easy for users to filter and search.

Next, the exam management module is the focus of the entire system. We need to design an exam scheduling interface to support administrators or teachers to create, edit, and delete exams. Each exam has a unique exam ID and corresponding exam name, time and location information. In the test management module, we also need to design a test score management function to facilitate administrators or teachers to view and count students' answers.

In the question answering management module, we need to design a question answering interface to support students in online answering operations. Students can choose to take the exam that has been created, answer the questions and submit their answers according to the requirements of the questions. The system needs to automatically correct the answer results and give corresponding scores and feedback. Students can view their answer records and scores in the answer management module.

Finally, system security is very important. We need to design a security authentication function to ensure that user information and answer data are not leaked or tampered with. In the user registration and login interface, we can use verification codes and other methods to verify the user's identity. In the answer management module, we can use encryption algorithms to protect the security of answer data.

The following is a simple code example to implement the user management module of a system that supports multiple users of schools or institutions in online answering:

class User:
    def __init__(self, username, password, role, school):
        self.username = username
        self.password = password
        self.role = role
        self.school = school

class UserManager:
    def __init__(self):
        self.users = []

    def register(self, username, password, role, school):
        user = User(username, password, role, school)
        self.users.append(user)

    def login(self, username, password):
        for user in self.users:
            if user.username == username and user.password == password:
                return user
        return None

# 示例代码使用了面向对象的方法，创建了一个User类和UserManager类。
# User类包含了用户名、密码、角色和所属学校等属性；
# UserManager类包含了用户注册和登录的方法。

user_manager = UserManager()
user_manager.register("admin", "admin123", "admin", "学校A")
user_manager.register("teacher1", "teacher123", "teacher", "学校A")
user_manager.register("student1", "student123", "student", "学校A")

user = user_manager.login("admin", "admin123")
if user is not None:
    print("用户登录成功！")
    print("用户角色：", user.role)
    print("所属学校：", user.school)
else:
    print("用户登录失败！")

This is just a simple example, the actual online answering The system still needs further improvement and refinement. I hope these ideas and code examples will be helpful to you when designing a system to support multiple users in a school or institution during online quizzes.
