- introduction
- research background and meaning
Student performance management is an important part of school work, and the level of student performance management in colleges and universities in our country is generally not high. With the expansion of school scale and the increase of enrollment, it is very necessary to establish a performance management system. Ordinary performance management wastes a lot of manpower and material resources, and can no longer adapt to the development of the times. In today's information age, this traditional management method must be replaced by a computer-based information management system.
On the basis of most grade management systems, this system mainly adds the teacher's operation on the grades. After the teacher corrects the test papers, he does not need to report the grades to the Academic Affairs Office of the college, but can directly upload the grades to the network, and the students can also You can easily and quickly check your own results. After the exam, the academic administrators don’t have to stay in the college’s office all the time. They are not limited by time, location, and space. As long as they have access to the Internet, they can complete the relevant results at home. Enter, update, manage, query and delete. This system will change the previous situation of manually managing student grades and improve work efficiency. Hope it can bring convenience to the work of teachers and schools.
- development status
In foreign schools, unlike domestic schools, they generally have a relatively large and stable technical team to provide services and technical support. However, the information construction of domestic schools started relatively late. In the process of gradually applying the digital campus theory, on the one hand, schools continue to invest in the purchase and construction of various hardware, system software and networks; on the other hand, they also continue to develop and implement various application systems for teaching, scientific research, office management, etc. Large-scale information construction system. However, due to the relatively backward level of overall informatization, shortage of funds, and unsound theoretical system, the educational administration management system of domestic schools has a certain gap compared with foreign schools in terms of organizational setup, service scope, service quality, and personnel requirements.
Looking at the current domestic research status, there are certain deficiencies in security and information updating. The data of each existing system is established separately, and the sharing is poor; Cognition and preferences, it is not easy to grasp the real needs of users, and therefore cannot fully meet the needs of users. Therefore, the educational administration software should fully rely on the campus network to realize the centralized management, decentralized operation, and information sharing of educational information, so that the traditional educational administration can develop in the direction of digitization, paperless, intelligent, and comprehensive, and further realize the perfect It has laid a good foundation for the advanced computer educational administration management system and the whole school information system.

- Related technology introduction
- Development technical description:
The front-end part of the system is developed based on the MVVM model, using the B/S model, and the back-end part is developed based on the Django framework of python.
Front-end part: The front-end framework adopts the popular progressive JavaScript framework Vue.js. Use Vue-Router and Vuex to achieve dynamic routing and global state management, Ajax to achieve front-end and back-end communication, Element UI component library to make the page quickly prototype, and the front-end of the project realizes responsiveness through grid layout, which can be adapted to PC, tablet, mobile, etc. Perfect layout display for different screen sizes.
Back-end part: Django is used as the development framework, and Redis and other related technologies are integrated at the same time.
- Introduction to Python
Python is a high-level scripting language that combines interpretability, compilation, interactivity, and object orientation. The design of Python, compared to other languages that often use English keywords and some punctuation marks in other languages, it has a more distinctive grammatical structure than other languages, and is very readable.
Interpreted language: similar to Python and Perl, which means that there is no compilation link in the development process.
Interactive language: code can be executed directly after a Python prompt >>>.
Object-Oriented Language: Python supports an object-oriented style or programming technique in which code is encapsulated in objects.
- Django framework
The Django project is a custom Python framework that was released as open source in 2005 from an online news Web site. The core components of the Django framework are:
1. Object Relational Mapping for Model Creation
2. Perfect management interface designed for end users
3. First-class URL design
4. Designer friendly template language
5. Cache system.
Django (pronounced: [`dʒæŋɡəʊ]) is an open source web framework (open source web framework) written in the python language, which encourages rapid development and follows the MVC design. Django complies with the BSD copyright, was first released in July 2005, and released the first official version 1.0 in September 2008.
Django is named after Django Reinhardt , a Belgian jazz musician . He is a gypsy who mainly plays the guitar and also the violin.
Due to the rapid development of Django in recent years, Django has become more and more widely used. It was selected as the 2013 SD Times 100 by the famous IT development magazine SD Times, ranking 6th in the category of "API, library and framework", and is considered to be the best in this field. By.
- Mysql database
Mysql has been updated many times, and the functional level has been very rich and perfect. From Mysql4 version to 5 version, a relatively large update has been made, and it has achieved good practical application results in actual commercial use. The latest version of Mysql supports the compression of information, and at the same time, it can also perform encryption to better meet the needs of information security. At the same time, after multiple updates of the system, the mirroring function of the database itself has also been greatly enhanced, the smoothness of operation and ease of use have been greatly improved, and the use and creation of drivers are also more efficient and faster. The biggest change is the optimization of the display of spatial information, which makes it easier to label and calculate coordinates on the application map. The powerful backup function also ensures that users will feel more at ease during the use process, and the supported Office features also support users' self-installation and use. The display form of information has also been greatly updated, and two very useful display areas have been added, one is the information area, which has classified tables and text, and the display of the interface is more refreshing and specific. The second is the information control of the instrument, which can display information in the instrument information area and compare multiple information at the same time, which brings great convenience to the actual use of users [8][9].
In the actual implementation process of the square dormitory management system designed in this article, the main reason for choosing the Mysql database is that there will be a large number of databases that are frequently operated during the application and development of the enterprise application system, and the data security The requirements are also very high. Based on these factors, Mysql with a relatively high safety factor was finally selected to store the background data of the Square News website.
The overall structure diagram of the database management system is shown in the figure below.
Figure 2-1 Database structure
- Working principle of B/S system:
The B/S architecture adopts the working mode of browser request and server response.
Users can access information such as text, data, pictures, animation, video on demand and sound generated by the web server on the Internet through a browser;
And each web server can be connected with the database server in various ways, and a large amount of data is actually stored in the database server;
Download the program from the Web server to execute locally. If an instruction related to the database is encountered during the download process, the Web server will hand it over to the database server for interpretation and execution, and return it to the Web server, and the Web server will return it to the user. In this structure, many networks are connected together to form a huge network, that is, the global network. Each enterprise can build its own Internet on the basis of this structure.
In the B/S mode, the user requests access to many servers distributed on the network through the browser. The browser's request is processed by the server, and the processing result and corresponding information are returned to the browser. Other data Processing and requests are all completed by the Web Server. Through the frame structure and the browser embedded in the operating system, this structure has become the mainstream structure mode of today's software applications.
- system analysis
- Feasibility Analysis
This design is based on the B/S mode, and the Python technology is used to implement Mysql database and HBuilder. The overall feasibility is divided into the following three aspects.
- Technical Feasibility Analysis
The so-called technical feasibility refers to whether the functions planned in the early stage can be satisfied within a limited time. Whether there will be problems that cannot be solved in the development and design. Whether the completed project can be well applied, if there are shortcomings, whether there is great difficulty in later maintenance. After evaluating the system, it was determined that existing technology could achieve the goals. Using python technology to realize dynamic pages, embedding low-dependency design patterns, flexible databases, and stable servers, the operating efficiency of the entire system is greatly improved. It can be seen that achieving the goal at the technical level is not a nonsense.
- Economic Feasibility Analysis
Most of the tools used in the project are currently popular open source and free, so in the early stage of development, the funds used for the project will be greatly reduced, and the development of the software will not be affected by the funds during the project start-up period, so It is still economically feasible. Try to use the least cost to meet the needs of users. Save funds for labor costs and equipment costs. It will go further and further on the road of paperless and high efficiency.
- Operational Feasibility Analysis
The operation of this system to realize the function is very simple. The common configuration of ordinary computers can run this software, and as long as you have a rough understanding of the basic common sense of computer use, you can use this software smoothly. The computer has the ability to connect to the Internet and can access the system normally. It does not require the operator to have any superb ability. It only needs to understand the business process and operate correctly according to professional knowledge. Therefore, the student performance management system is operationally feasible.
- Functional Requirements Analysis
Before system development and design, you should make a preliminary idea of the functions, know what sections the management system has, what functions each section has, whether the overall design meets the needs of users, and then conduct a detailed analysis and summary of the developed system functions , so as to design a complete system and implement it. Communication analysis of users and developers to achieve the best understanding and make the system function to the best.
The student use case diagram is shown below.
Figure 3-1 Student use case diagram
The administrator use case diagram is shown below.
Figure 3-1 Administrator use case diagram
The teacher use case diagram is shown below.
Figure 3-1 Teacher use case diagram
After analyzing the requirements of the student performance management system, the whole system is mainly divided into three parts: administrators, teachers, and students. The branch functions of each module are different. Describe the function as follows:
Student Module:
Account login authentication.
Manage profile information, modify modifiable information items.
Student performance information query, query personal results.
Teacher Module:
Submit student grades, and at the same time view historical submitted student grade records.
Admin module:
Maintain students, review student accounts, freeze student login permissions, or delete student accounts.
Publish teachers, and can destroy a certain teacher, update teacher data, fuzzy search teacher data, etc.
View student performance data submitted by teachers, and administrators have the right to maintain it.
- Non-Functional Requirements Analysis
There are many non-functional requirements of the system, such as performance requirements, maximum number of users that can be carried, stability, and usability requirements. The analysis of this system takes into account the requirement of ease of use, because the system is used by people, so it is necessary to fully consider the user experience from the user's point of view, so that the system is easy to understand, easy to use and easy to operate.
- Data Flow Analysis
The zero-level data flow chart includes modules such as login, user function, and retrieval maintenance. The data used in the login module stores user account documents, and the storage required by the user function module is the data file of each user function module. The retrieval maintenance uses the above Data documents are retrieved by keywords.
The zero-level data flow diagram of the system is shown in the figure below.

- 系统设计
- 系统架构设计
目前B/S体系的系统主要的数据访问方式是：通过浏览器页面用户可以进入系统，系统可以自动对用户向服务器发送的请求进行处理，处理请求是在系统后台中进行的，用户在浏览器页面上进行相应操作，就能够看到服务端传递的处理结果。学生成绩管理系统主要分为视图-模型-控制三层架构设计。在视图层中，主要是操作在服务器端向客户端反馈并显示的数据，在模型层中，主要处理相关的业务逻辑、数据整合等，最后的控制层它介于视图和模型之间，主要是调整两层之间的关系，最终落实数据的传递。
系统架构图如下图所示。
图4-1系统架构图
- 系统功能结构
系统设计的目的是分析系统包括的所有功能结构，为开发人员设计开发和实现系统做好准备工作。经过前期的需求调查、分析和整理之后，确定的总体需求主要包括多个模块，分别是：用户管理、教师管理、学生管理、课程成绩管理、学生成绩管理。系统整体角色分为三个部分，一是学生、二是教师用户、最后是管理员。权限分布也是很明显，普通用户是在除去浏览信息之外还具有查询和管理账户信息、学生资料管理、学生成绩、等权限；管理员是最高权限拥有者。
系统功能结构图如下图所示。
图4-2系统功能结构图
- 功能模块设计
学生管理模块
该模块是为所有用户登录设计的，如学生用户这种普通用户登录后只能进行自己的普通功能操作(如个人信息修改），管理员和超级管理员登录后有不同的权限，管理员不能超越权限。超级管理员能对整个系统的数据进行管理，主要是用户的登录权限以及用户登录后在系统里的操作权限。
教师维护模块
操作人来录入教师数据，点击教师录入按钮，依次填写要录入的教师数据，点击提交按钮，将数据提交至数据库，然后刷新教师数据页面，每条数据右边有删除和编辑按钮，来完成相应的删除和更新功能。
- 表单字段校验处理设计
1.出错信息类型
出错信息类型包括：
A 未输入必填项；
B 应输入合法字符或数字却输入非法字符或数字；
C 对空数据表进行更改或删除操作；
D 向要求唯一值的关键字段添加重复值。
2.出错处理对策
对于错误A，系统要求用户输入非空值。
对于错误B，系统要求用户输入合法字符。
对于错误C，系统提示数据表无记录可更改或删除。
对于错误D，系统要求用户输入非重复值。
- 系统维护设计
学生成绩管理系统是个现代化的高度集成的综合信息系统，系统主要服务对象为用户，最大化在页面中提供多的信息，因此在系统维护上，数据量较大，整体的维护设计如下：
（1）代码的维护：部署在云服务器上或本地服务器，通过SVN或FTP保持版本更新迭代。
（2）功能增加：功能升级在必要的前提下。
（3）数据维护：根据安全性等需求，定期对数据库进行人工备份。
- 数据库设计
- 概念模型
对于一个要开发的系统来说，E-R图可以让别人能更快更轻松的了解此系统的事务及它们之间的关系。根据系统分析阶段所得出的结论确定了在学生成绩管理系统中存在着多个实体分别是用学生、教师、管理员、成绩、。
系统总体ER图如下图所示。
图4-4系统总体ER图
- 关系模型
管理员（管理员id、用户名、密码、权限）
学生（学生id、学号、学生姓名、性别、年龄、专业、班级名称、审核状态、用户id）
教师（教师id、工号、教师姓名、性别、职称、审核状态、用户id）
学生成绩（学生成绩id、学生、学号、学生姓名、专业、班级名称、科目、成绩）
- 数据表
数据库逻辑结构就是将E-R图在数据库中用具体的字段进行描述。用字段和数据类型描述来使对象特征实体化，最后形成具有一定逻辑关系的数据库表结构。学生成绩管理系统所需要的部分数据结构表如下表所示。

- 系统实现
- 登录模块的实现
系统的登录窗口是用户的入口，用户只有在登录成功后才可以进入访问。通过在登录提交表单，后台处理判断是否为合法用户，进行页面跳转，进入系统中去。
登录合法性判断过程：用户输入账号和密码后，系统首先确定输入输入数据合法性，然后在login.python页面发送登录请求，调用登录验证方法来验证。
用户登录模块的IPO如下所示：
输入：用户名和密码。
处理：
1）检测用户输入的账号、密码是否正确及在数据库已对应存在。
2）从数据库中提取记录，并储存在本地的session中（timeout默认=30min）。
3）根据用户名，将其显示在系统首页上。
输出：是否成功的信息。

- 测试结果
经过对此系统的测试，得出该系统足以满足用户日常需求，在功能项目和操作等方面也能满足操作员对于其他用户的管理。但是，还有很多功能有待添加，这个系统仅能满足大部分的需求，还需要对此系统的功能更进一步的完善，这样使用起来才能更加的完美。
- 总结与展望
通过学生成绩管理系统的开发，本人巩固了之前学过的知识，如今将平时所学到的知识融合在设计中，在设计过程中，做了很多的准备，首先，在数据库系统的设计过程中，尤其是在数据库的工作原理、工作特点，对其深刻的讨论，与此同时，对于小型站点来说，最好服务器的选择，其次，利用所学的知识点分析所做的系统，并在此基础上设计。
目前本系统已经上线，正在试运行阶段，用户反馈良好，基本完成用户所需，试运行过程中没有出现阻断性问题，有一些不足和小问题也及时予以修正，系统上线后，为了保证数据的安全性，对系统进行了备份操作，系统备份是每两个月备份一次，数据库备份为每周备份一次，系统部署在租赁的云平台服务器中。
本次系统上线成功后，得到了用户的高度认可，但是在功能上和性能上还需做进一步的研究处理，使其有更高的性能和更好的用户体验。
系统在以后的升级过程中，需要解决一系列用户所提出的问题，例如打印过程中如何避免浏览器的兼容性问题，大量用户访问时，如何保持较高的响应速度，在系统今后的升级过程中将着重解决这些安全性问题。
