二、系统需求分析
System Requirements Analysis
在当今信息化、数字化的时代背景下，学生选课系统的设计与实现显得尤为重要。

一个完善的学生选课系统不仅可以提高学校的教学管理效率，还可以为学生提供更加便捷、灵活的选课体验。

因此，我们深入分析了学生选课系统的实际需求，以确保系统的功能和性能能够满足用户的期望。

In the current era of informatization and digitization, the design and implementation of student course selection systems are particularly important. A comprehensive student course selection system can not only improve the efficiency of school
teaching management, but also provide students with a more convenient and flexible course selection experience. Therefore, we conducted an in-depth analysis of the actual needs of the student course selection system to ensure that the system's functionality and performance can meet user expectations.
系统需要支持多种角色登录，包括学生、教师和管理员。

学生需要能够查看课程信息、选择课程、查询选课结果等；教师则需要能够管理自己的课程、查看选课学生名单等；管理员则需要对整个系统进行维护和管理，包括用户管理、课程管理、选课规则设定等。

The system needs to support multiple roles for login, including students, teachers, and administrators. Students need to be able to view course information, select courses, query course selection results, etc; Teachers need to be able to manage their own courses, view the list of selected students, and so on; Administrators need to maintain and manage the entire system, including user management, course management, and course selection rule settings.
系统需要具备良好的用户界面和交互设计，以确保用户可以轻松上手并愉快地使用。

系统还需要提供详细的帮助文档或在线帮助，以
便用户在使用过程中遇到问题能够及时解决。

The system needs to have a good user interface and interaction design to ensure that users can easily get started and use it happily. The system also needs to provide detailed help documents or online help, so that users can solve problems in a timely manner during use.

At the same time, the system also needs to support multiple course attributes, such as course name, credits, class time, class location, etc., so that users can have a comprehensive understanding of course information.
在性能方面，系统需要保证高并发访问时的稳定性和可靠性，以应对大量学生同时选课的情况。

同时，系统还需要具备数据备份和恢
复功能，以确保数据的安全性和完整性。

In terms of performance, the system needs to ensure stability and reliability during high concurrency access to cope with the situation where a large number of students choose courses simultaneously. At the same time, the system also needs to have data backup and recovery functions to ensure the security and integrity of data.
系统需要具备良好的扩展性和可维护性，以便在未来能够方便地添加新功能或进行升级维护。

The system needs to have good scalability and maintainability in order to easily add new features or perform upgrades and maintenance in the future.
学生选课系统的需求分析涉及多个方面，包括功能需求、性能需求、安全性需求、扩展性和可维护性需求等。

我们将根据这些需求来设计和实现系统，以确保其能够满足用户的期望并为学校的教学管理带来便利。

The requirement analysis of the student course selection system involves multiple aspects, including functional requirements, performance requirements, security requirements,
scalability and maintainability requirements, etc. We will design and implement the system based on these requirements to ensure that it meets user expectations and brings convenience to the school's teaching management.
三、系统设计
System design
在《学生选课系统的设计与实现》中，系统设计部分是整个项目的核心。

本系统的设计主要围绕用户需求、功能设计、数据库设计、系统架构设计等几个方面展开。

In the design and implementation of the student course selection system, the system design part is the core of the entire project. The design of this system mainly revolves around user requirements, functional design, database design, system architecture design, and other aspects.
我们根据用户需求调研，明确了系统的基本功能。

学生选课系统需要支持学生登录、课程浏览、课程选择、退选、查询选课结果、查看课表等基本功能。

同时，系统还需要为教师和管理员提供课程管理、学生选课情况查看等功能。

We have conducted research based on user needs and clarified the basic functions of the system. The student course selection system needs to support basic functions such as student login, course browsing, course selection, withdrawal, query course selection results, and view course schedules. At the same time, the system also needs to provide functions such as course management and viewing of student course selection for teachers and administrators.
在功能设计方面，我们采用了模块化设计思想，将系统划分为多个独立但又相互关联的模块，包括用户管理模块、课程管理模块、选课管理模块、课表管理模块等。

每个模块都有其特定的功能和数据流程，这种设计方式不仅提高了系统的可维护性，也使得系统的扩展性更强。

In terms of functional design, we adopted a modular design concept, dividing the system into multiple independent but interrelated modules, including user management module, course management module, course selection management module, schedule management module, etc. Each module has its specific functions and data flow, which not only improves the
maintainability of the system but also makes it more scalable.
数据库设计是系统设计的关键环节。

我们根据系统功能需求，设计了包含学生信息表、课程信息表、选课信息表等多个数据表的数据库结构。

同时，我们还考虑了数据的完整性、安全性和并发性等问题，采取了相应的措施，如设置主键、外键约束，使用视图、存储过程等技术，确保数据库的稳定性和安全性。

Database design is a crucial aspect of system design. We have designed a database structure that includes multiple data tables such as student information table, course information table, and course selection information table based on system functional requirements. At the same time, we also considered issues such as data integrity, security, and concurrency, and took corresponding measures, such as setting primary and foreign key constraints, using technologies such as views and stored procedures, to ensure the stability and security of the database.
在系统架构设计方面，我们采用了C/S架构和B/S架构相结合的方式。

对于选课、退选等交互性较强的功能，我们采用了C/S架构，通过客户端程序实现与服务器的交互；而对于课程浏览、查询选课结
果等较为简单的功能，我们则采用了B/S架构，用户只需通过浏览器即可访问系统。

这种混合架构的设计方式既满足了系统的功能需求，又提高了系统的易用性和可维护性。

In terms of system architecture design, we adopted a combination of C/S architecture and B/S architecture. For interactive functions such as course selection and withdrawal, we have adopted a C/S architecture and implemented interaction with the server through client programs; For simpler functions such as course browsing and querying course selection results, we adopt a B/S architecture, where users only need to access the system through a browser. This hybrid architecture design approach not only meets the functional requirements of the system, but also improves its usability and maintainability.
通过对用户需求、功能设计、数据库设计、系统架构设计等方面的综合考虑和精心设计，我们完成了学生选课系统的系统设计工作。

接下来，我们将根据这个设计方案进行系统的实现和测试工作。

Through comprehensive consideration and careful design of user requirements, functional design, database design, system architecture design, and other aspects, we have completed the
system design work of the student course selection system. Next, we will implement and test the system based on this design scheme.

管理员可以在该模块中设置系统参数、备份数据库、查看系统日志等，以确保系统的正常运行和数据的安全性。

We have implemented system management and maintenance modules. Administrators can set system parameters, backup databases, and view system logs in this module to ensure the normal operation of the system and the security of data.
在整个系统实现过程中，我们采用了面向对象的编程思想，使用Java语言进行开发。

同时，我们还采用了MVC架构，将系统划分为模型、视图和控制器三个层次，提高了系统的可维护性和可扩展性。

Throughout the entire system implementation process, we adopted an object-oriented programming approach and developed it using the Java language. At the same time, we also adopted the MVC architecture, dividing the system into three levels: model, view, and controller, which improved the maintainability and scalability of the system.
通过不断地调试和优化，我们最终完成了学生选课系统的各个功能模块的开发和集成，并进行了全面的测试。

测试结果表明，该系统功能完善、性能稳定、操作简便，能够满足学生和管理员的需求。

Through continuous debugging and optimization, we have finally completed the development and integration of various functional modules of the student course selection system, and
conducted comprehensive testing. The test results show that the system has complete functions, stable performance, and easy operation, and can meet the needs of students and administrators.
以上即为学生选课系统的设计与实现过程中的系统实现部分。
