Summary
With the rapid development of information technology and network technology, human beings have entered a new era of information, and traditional management techniques have been unable to manage information efficiently and conveniently. In order to meet the needs of the times and optimize management efficiency, various management systems have emerged as the times require, and all walks of life have entered the information management era one after another. The student performance management system is one of the products of the transformation of the information age.
Any system must follow the basic process of system design, and this system is no exception. It also needs to go through the steps of market research, demand analysis, general design, detailed design, coding, and testing. Based on the java language, the student achievement management system is designed and implemented. The system is based on B/S, the so-called browser/server model, using java technology, and choosing MySQL as the background database. The system mainly includes home page, personal center, student management, teacher management, class management, comprehensive achievement management, professional management , course information management and other functional modules.
This paper first introduces the technical development background and development status of student performance management, and then follows the software development process, first selects the applicable language and development platform for the system, formulates modules and designs database structures according to demand analysis, and then according to the overall functional modules of the system Design and draw the functional module diagram, flowchart and ER diagram of the system. Then, design the framework and write codes according to the designed framework to realize each functional module of the system. Finally, test the preliminarily completed system, mainly function test, unit test and performance test. The test results show that the system can realize the required functions, and the operating condition is not obvious .

1 Introduction
1.1 Subject background
With the development of science and technology, computers have become an indispensable tool for people's daily life and office work. In this context, network technology has been applied to various aspects. In order to improve the efficiency of office life, network information technology has developed rapidly. In this context, human society has entered a new era of information technology. Student grade management has always been a major problem in information management. There are a large number of student grades. At this time, it is imperative to find an effective and convenient method of student grade management. The increasingly mature computer information management technology has become the first choice to solve this problem. Nowadays, computer information management technology has been able to deal with student performance management with ease. In fact, information management technology has penetrated into the information control management of various industries, and has a pivotal position. With the continuous progress of modern socialism, the living standards of ordinary people have been greatly improved, and many aspects are realized on the Internet, so the Internet has become the most direct, convenient and fast access.
Using the student performance management system has many advantages compared to the traditional student performance management method: firstly, it can greatly improve the retrieval of student performance information, and the desired result can be fed back within a few seconds only by inputting the relevant information of the grade; secondly, it can store a large amount of student performance information, At the same time, the security of student performance information is more guaranteed; compared with paper documents to manage student performance information, the student performance management system saves space and human resources. These advantages greatly improve operational efficiency and save operating costs. Therefore, it is necessary to develop a student performance management system to effectively manage student performance information, which not only improves the efficiency of student performance management, increases the security of user information, facilitates timely feedback to administrators, and increases the number of users and administrators. The interaction between students can improve the experience intensity of student performance management.
This system intends to use MySQL to design the database for the flexibility of the database structure, while java technology and B/S architecture guarantee high platform adaptability. This article mainly introduces the development background of the system, the functions to be completed and the development process, and mainly explains the key points and design ideas of the system design.
1.2 Current status of subject research
Nowadays, more and more people are willing to choose a suitable management plan, but ordinary users are often limited by management experience. At this time, the rise of the student performance management system, a large number of student performance management systems have entered people's lives, and the student performance management system It is undoubtedly the best system for student performance management. Under the background of such a successful management model, there are more and more student performance information. However, with the increase of student achievement information, the management of student achievement has become a difficult problem. Efficient and convenient management of student performance has become an urgent task to change the management model and be compatible with the times.
The student performance management system provides a convenient method for users to view student performance information anytime, anywhere, and more importantly, it greatly simplifies the way administrators manage student performance information, and provides other information and operating conditions for students who want to know student performance information And choose convenient and reliable channels. Compared with the traditional student performance management methods, such electronic information management is more concise and convenient, and it also has unique advantages in the aspects of student performance management, maintenance information feedback and handling of student performance management opinions.
2 System development environment
2.1 Java Technology
Java is a cross-platform object-oriented programming language launched by Sun. Because Java technology has the characteristics of excellent versatility, high efficiency, robust security and platform portability, and Java is open source and has the world's largest developer professional community, so Java develops rapidly.
2.2 B/S mode
The B/S structure is currently the most used structural mode, which can make the development of the system easier, easier to operate, and can also be maintained. When using this structure, you only need to install the database in the computer and some very common browsers. The browser will connect information with the database, which can realize many functions. The B/S structure can be used directly, and the B/S structure greatly reduces the maintenance of work during use. Based on B/S software, all databases are independent of each other, so it is very safe. Because based on the B/S structure, you can clearly see the business being processed by the system, and you can let the managers make decisions in a timely manner, so that you can avoid the loss of the enterprise. The basic feature of the B/S structure is the centralized management mode. After the user uses the system to generate data, the data can be stored in the system database for future use, so that all people's needs can be met.
