1.1 Background and significance of the topic
The rapid development of the Internet has fundamentally changed the management methods of organizations around the world. Since the 1990s, our country's government, enterprises and institutions have imagined that information can be managed through the Internet system. Due to various reasons in the past, such as low network penetration, user rejection, insufficient Internet-related laws and regulations, and immature development technology, the development speed of the Internet in major institutions was hindered. After entering the 21st century, my country's economy has developed rapidly, and various problems restricting institutional management have been solved one by one. All major domestic institutions have joined the electronic information management model.
In the past, information management related to the subject competition management system was done manually by staff. This method is not only timely but also inconvenient when searching and changing. With the advancement of science, the maturity of technology, and the rapid development of computer informatization, society has also gained a profound understanding that computers are very powerful. Computers have entered various fields of the development of human society and play a very important role. This system uses network communication and computer information storage and management, and has advantages that cannot be replaced by traditional methods. For example, the calculation and retrieval speed is extremely fast, the reliability is extremely high, the storage capacity is extremely large, the confidentiality is extremely good, the storage time is extremely long, and the cost is extremely low. In terms of work efficiency, it can be greatly improved, and there will be good gains when extended to the service level. With the network, the management of all aspects of the subject competition management system is more scientific and systematic, more standardized and simpler.
1.2 Research status at home and abroad
With the continuous penetration of computer networks, the way people live, work, and study is slowly changing. Traditional user-related information management methods generally adopt manual methods, and the acquisition, organization, modification, and storage of information are still in the manual stage. On the one hand, this method requires a lot of manpower, material resources and money, is difficult to interact with, and wastes time; on the other hand, the management of user and other information, especially as the number of users increases, is particularly difficult to query and modify. ; Finally, due to the continuous increase of users and other information, the storage of information has also become a problem.
In some developed countries, the Internet has developed relatively quickly and has largely completed the transition from manual to computer management. Computer application in our country started relatively late, and the development regions are unbalanced. There are still many regions or units using traditional methods for management. However, computers are developing rapidly, including the popularization of the Internet. Many units and users are slowly beginning to come into contact with network management. system. Looking at these systems, they mainly have the following characteristics:
(1)Advancement: realize network management.
(2) Versatility: It can basically be used in the same industry.
(3) Convenience: Management work can be completed through the Internet.
(4) Timeliness: Information is updated in a timely manner.
(5) Scalability: Modules can be added as needed.
(6) Security: Encrypt unit, user and other information.
Up to now, the Internet has penetrated deeply into people's lives. Smartphones, laptops, etc. have become the main tools for people to obtain information. This is an era of unlimited communication. Therefore, it has become a general trend to use the Internet to manage subject competition management systems. Therefore, , it is necessary to develop a subject competition management system.
1.3 Main work of this topic
At the beginning, this article gives an overall description of the basic knowledge discussed in the system, and conducts a system analysis on this basis. In order to enable this system to be designed and implemented in a better and more complete manner, analysis and investigation must be conducted first. Based on the previous related foundations, a detailed analysis of the new system was carried out in terms of functionality. Then through detailed analysis, system design was carried out. Secondly, in terms of the feasibility of system implementation, I chose Java technology for development and design. For data storage, I used Mysql database for design. Since both Java and Mysql are very mature, they are very reliable, safe and practical in all aspects. Finally, the system is tested, perfected and released.
2 System development environment
2.1 java technology
The Java language was released by Sun at the end of the 20th century, and the source code was open. This advantage attracted many outstanding programming enthusiasts from all over the world, and also enabled them to develop classic and fun games one after another at that time. The Java language is one of the pure object-oriented languages. From the early days of its release to the present, it can be said that it has a history of nearly 20 years and has developed into a profound influence in the history of human computer programming language development.
The Java language has a variety of features: (1) Cross-platform independence; (2) Object-oriented; (3) Security is guaranteed; (4) Supports multiple tasks; (5) Multiple writing methods, code writing Simple. Compared with other low-level languages and high-level languages, the Java language has obvious advantages and broad prospects in the future. It can be widely used in personal laptops, big data, large-scale games, etc.
First of all, the Java language has object-oriented characteristics and is easy to understand. Regarding objects, it can actually be understood that every thing is an object, including us humans. Utilize the basic characteristics of object-oriented languages to solve practical problems in software development and provide technical support for effective software development.
Secondly, the Java language has good cross-platform independence. The application program written is written in Java language, so there is no need to use a compiler to modify the program code, and it can be run directly on any computer system, including Windows systems and Linux systems, that is, after one compilation , can run everywhere, so the Java language has excellent portability and can be implemented well across platforms.
2.2 Mysql database
Mysql is a multi-user, multi-threaded server that uses SQL database. The database management system is based on the relationship between SQL client and server modes. Its advantages include powerful functions, simple operation, convenient management, reliability and security, and fast operation. , multi-threading, cross-platform, fully networked, stable, etc., it is very suitable for the development of Web sites or other application software in the database back-end. In addition, using many languages, members can write and access MySQL database programs. Mysql database is also open source. Developers are increasingly fond of using Mysql relational database, and its application scope has also been extended. Because of its speed and ease of use, it is also used in the development of database backends for Web sites or application software.
The mysql database has many advantages, such as its easy-to-understand operation, powerful functions, and high information storage capacity. Therefore, it is widely used by people. For mysql database, it is generally mainly used for encoding and querying data, and it is applied to this database in many designs. In this process, we can query and combine conventional data, so When we use the mysql database, we only need to write a small piece of data to achieve the corresponding function. A database is a storage room for data storage, but the data is stored on a computer instead of a real storage room. The data is stored in a fixed format, not disordered. The definition is: a fixed format for a long time. Storage on computer memory that can be shared. Database management mainly includes the establishment of data tables, data storage, modification and addition of data. In order to ensure that the database system can operate normally, the management work carried out by relevant personnel. The establishment of the data table can adjust the data in the data table, recombine and reconstruct the data to ensure the security of the data.
2.3 B/S structure
The BROWSER/SERVER program architecture uses various browsers installed on the computer to access and use it. Compared with the C/S program structure, it can be used directly without the need for program installation. The way the BROWSER/SERVER architecture works is to install one on a remote server and then access and use it on any computer connected to the Internet. The development method of BROWSER/SERVER architecture brings great convenience to users, and the developed program system can be used at any time and place.
In the B/S structure, users can access and use the functions of the system website anywhere with access to the Internet. There are no restrictions on region or time. The B/S structure places the program completely on the server of the computer network. The computer Internet provides users with remote network services. In the B/S system with a three-tier architecture, members can make requests to many servers through the browser. The B/S system will greatly reduce the workload. Users only need to install and run fewer clients. A large amount of work will be undertaken by the server. In addition, the server also completes work including accessing the database, executing application programs, etc.
The B/S structure mainly has three layers, namely data layer, control logic layer and view layer. Through the view layer, the user allows the control layer to call the data of the data layer, thereby achieving the entire access process. The three layers are independent of each other, easy to maintain and safe to use. The three layers call each other to improve efficiency.
2.4 Introduction to ssm framework
The SSM (Spring+SpringMVC+MyBatis) framework set is integrated by the two open source frameworks Spring and MyBatis (SpringMVC is part of Spring). It is often used as a framework for web projects with relatively simple data sources.
2.4.1 Spring
Spring is like a big factory that assembles beans in the entire project. In the configuration file, you can specify the use of specific parameters to call the constructor method of the entity class to instantiate the object. It can also be called the glue in the project.
The core idea of Spring is IoC (Inversion of Control), which means that programmers no longer need to explicitly `new` an object, but let the Spring framework do it all for you.
2.4.2 SpringMVC
SpringMVC intercepts user requests in the project. Its core Servlet, DispatcherServlet, assumes the responsibility of intermediary or front desk, and matches user requests through HandlerMapping to the Controller. The Controller is the specific operation performed in response to the request. SpringMVC is equivalent to struts in the SSH framework.
2.4.3 mybatis
mybatis is an encapsulation of jdbc, which makes the underlying operations of the database transparent. The operations of mybatis are centered around a sqlSessionFactory instance. Mybatis is associated to the Mapper file of each entity class through the configuration file. The Mapper file is configured with the SQL statement mapping required for each class to the database. Every time you interact with the database, get a sqlSession through sqlSessionFactory, and then execute the sql command.
The page sends a request to the controller, the controller calls the business layer processing logic, the logic layer sends a request to the persistence layer, the persistence layer interacts with the database, and then returns the result to the business layer, the business layer sends the processing logic to the controller, and the controller then Call the view to display the data.
3 System analysis
The so-called system analysis means that demand personnel obtain information through communication with customers, and then display this information to users and developers in the form of demand specifications. In the long history of the development of software functions, for a long time, especially in the beginning, the importance of requirements analysis was not recognized by people. For example, at that time, the American company IBM developed an information management system for British Telecom. Development started without clarity, and the initial construction period was one year. Due to unclear requirements, the construction period was delayed by more than half a year, causing huge losses. This situation also exists in many of our software companies. They develop while developing, and even without clear communication with customers, directly copy the same type of projects and make changes. As a result, when the system is accepted, changes are made again, resulting in a loss of manpower and material resources. A huge waste. The reason for all these consequences is that the demand acquisition is not timely, unclear, and incomplete.
3.1 Feasibility analysis
The main goal of the subject competition management system is to realize related information management services of the subject competition management system. After determining the goals, we conduct a feasibility analysis on whether the goals of this system can be achieved from the following four aspects.
3.1.1 Technical feasibility
The subject competition management system mainly uses Java technology, based on B/S structure and Mysql database. The development of applications requires complete functions, simple use, and the establishment of a database with complete, safe and stable data. The development technology of the subject competition management system is highly feasible, and the developers have mastered certain development technologies, so the development of the system is feasible.
3.1.2 Operational feasibility
The login interface of the subject competition management system is simple and easy to operate. It uses a common interface window to log in to the interface and access it through a computer. Members can access it as long as they have used a computer. The development of this system uses Java language and is based on B/S structure. These development environments make the system more complete. This system has the characteristics of easy operation, easy management, good interactivity, and is very simple in operation. Therefore this system can be developed.
3.1.3 Economic feasibility
The subject competition management system is based on the B/S model and uses the Mysql database to store data. The required hardware and software environments are easy to purchase on the market. Program development is mainly the development and maintenance of the management system. Therefore, the program does not require high development manpower and financial resources, and the system is not very complex, the development cycle is short, and it has high economic feasibility.
3.1.4 Legal feasibility
This subject competition management system is a self-designed management system and has great practical significance. Because both the software and the database use open source code, the development and design of this system does not have problems such as infringement and is completely legally feasible.
In summary, the subject competition management system is technically, economically, operationally and legally feasible, and it is feasible to develop this program.
3.2 System process analysis
3.2.1 System development process
When developing a subject competition management system, first conduct a demand analysis, and then conduct an overall design plan for the system, design system functional modules, database selection, etc. The development process of this system is shown in Figure 3-1.
Figure 3-1 System development flow chart
3.2.2 User login process
In order to ensure the security of the system, if you want to use this system to manage system information, you must first log in to the system. As shown in Figure 3-2.
Figure 3-2 Login flow chart
3.2.3 System operation process
After the user opens and enters the system, the login interface will be displayed first, and the correct user name and password will be entered. The system will automatically detect the information. If the information is correct, the user will enter the system function interface and perform operations. Otherwise, an error will be displayed and the user cannot log in. The operation process is as follows As shown in Figure 3-3.
Figure 3-3 System operation flow chart
3.2.4 Add information process
Administrators can add information, etc. Students can also add information within their own authority. After entering the information, the system will verify the entered information and data. If the information is correct, it will be added to the database. If If the information is incorrect, you will be prompted to re-enter the information. The process of adding information is shown in Figure 3-4.
Figure 3-4 Add information flow chart
3.2.5 Modify information flow
Administrators can modify information, etc., and students can also modify information within their own permissions. First, enter the modification information interface, enter the modification information data, and the system will judge and verify the data. If the modified information is legal, the modification will be successful, and the information will be updated to Database, if the information is illegal, the modification will fail and re-enter. The modified information flow chart is shown in Figure 3-5.
Figure 3-5 Modify information flow chart
3.2.6 Information deletion process
The administrator can delete information, etc. After selecting the information to be deleted, click the delete button, and the system will ask if you are sure. If you click OK, the system will delete the selected information and update the information in the database. Delete, delete information flow chart is shown in Figure 3-6.
Figure 3-6 Deletion information flow chart
3.3 System use case analysis
3.3.1 Administrator use case diagram
The core user in the system is the system administrator. After the administrator logs in, he manages the backend system through the administrator menu. The main functions are: homepage, carousel, website announcements, resource management (competition information, information classification) communication management (competition communication, communication classification) system users (administrators, teacher users, student users) module management (competition classification, competition Information, competition registration, competition results, teacher notifications, student notifications, performance analysis) and other functions. The administrator use case is shown in Figure 3-7.
Figure 3-7 Administrator use case diagram
3.3.2 Student use case diagram
Students can enter the system for homepage, competition communication, competition registration, competition results, student notifications, etc. The student use case is shown in Figure 3-8.

3.3. 3 Teacher use case diagram
Teachers can enter the system to manage the home page, communication management (competition communication) module (competition information, competition registration, competition results, teacher notifications, performance analysis), etc. An example for teachers is shown in Figure 3-9.
Figure 3-9 Teacher use case diagram
4 System design
4.1 System Overview
After the system analysis, we begin to memorize system design. System design includes overall design and detailed design. The overall design is just a general design. After the overall design, we can divide some things of the system, such as files, documents, data, etc. And through the overall design, we can roughly divide the modules and functions of the program. But it is only a preliminary classification and has no real implementation.
The overall design is just a preliminary design. Moreover, for a project, we can carry out multiple overall designs. Through comparison, including performance comparison, cost comparison, and benefit comparison, we can finally determine an optimal design plan and choose the best one. The overall design can reduce development costs and increase company benefits. From this point of view, the overall design is still very important.
The working principle diagram of the subject competition management system is shown in Figure 4-1:
Figure 4-1 System working principle diagram
4.2 System structure design
The system architecture diagram belongs to the system design stage. The system architecture diagram is only a product of this stage. The overall architecture of the system determines the model of the entire system and is the foundation of the system. The overall structural design of the subject competition management system is shown in Figure 4-2.
Figure 4-2 System structure diagram
4.3 Database design
Database is the basis of computer information system. At present, the key and core part of the computer system is the database. The quality of database development has a direct impact on the quality and speed of the entire system.
4.3.1 Database design principles
The conceptual structure design of the database adopts the entity-relationship (ER) model design method. The constituent elements of the ER model method are: entities, attributes, and relationships. The ER model is represented by an ER diagram, which reminds the user of things involved in the work environment, and attributes are descriptions of entity characteristics. The database plays a decisive factor in system design. The entity-relationship diagram of these key entities is designed below.
4.3.2 Database ER entity
Entities in the data model, also called instances, correspond to "events" or "things" that can be distinguished from other objects in the real world. For example, every employee in your company, every piece of furniture in your home.
The ER diagram of this system is shown below:
1. The competition information management entity diagram is shown in Figure 4-3:
Figure 4-3 Competition information management entity diagram
2. The entity diagram of competition registration management is shown in Figure 4-4:
Figure 4-4 Student information management entity diagram
4.3.3 Database table design
The table information of the database is part of the design. The detailed information of each table in the database is introduced below.

6系统测试
系统开发的最后一个步骤就是系统测试，系统测试也是整个系统十分重要的一个环节，测试的好坏关系到产品的发展。客户对软件的质量、性能和可靠性等需求就要通过测试来实现。测试过程要必须遵循严谨性、完善性、规范性的原则，测试的主要目的就是看看在系统运行中，是否会出现bug，然后对出现的bug进行调试，直到程序完美运行。但是软件的测试只能尽可能的减少bug，理论上来说是无法达到消除bug。但是bug越少，系统出错的几率就越低，用户使用起来也更方便、更安全。
近年来，软件包含测试从现在的检验当中来看，系统接近预期目标可能出现的问题，并对这些错误做出相应的修正，假如我们不进行早期的测试错误就会延续下去，最后所做出的成品就会有很大的困难。
我们要在这个测试的过程当中找出错误。测试成软件开发的主要一部分，自从有了程序的设计那天开始，它就成为了重要的组成部分。经过统计来看，软件测试可以占据这个系统45%的工作量，而在软件开发的成本当中，对于测试成本来说它包含了很多的测试工作。每个程序测试时都会出现和遇到错误。在整个程序的开发过程当中，人为去查找错误是非常复杂和困难的，所以我们一般都会找一些测试的工具来进行测试
6.1系统测试的意义
随着现代信息的快速发展，在社会各大领域中已经都开始应用网络信息技术，在应用网络技术的同时人们也开始把软件的质量问题作为了一个重要焦点来关注，因为一个软件的好与坏它决定着这个系统在市场上的生存，所以我们必须要把软件质量来做好，这样才有一定的生存能力。对于用户来说它们首先选用的都是保证这个系统软件的质量问题，因为一个系统的软件质量决定着用户在后期上成本经济的问题。图6-1就是纠错测试流程。
图6-1 测试与纠错信息流程
6.2 测试方法
黑盒测试又被人们称作为功能测试，通常是在程序的接口来做一些测试的方法，它一般包括对程序的功能和使用的方法来做出一些数据的接受和输出，同时还可以做出正确的输出信息，并保证与外部信息的完整性。
白盒测试通常被人们称作为结构测试，在整个程序的结构和处理当中它是由程序当中的逻辑测试和检验程序来完成一些正确的工作。
具体的功能测试它是包括：系统的适用性、准确性、安全性等功能测试。
6.3测试分析
本学科竞赛管理系统满足相关信息的管理需求，在设计时借鉴了国内外优秀网站的优点，从界面到系统设计都保证了管理员以及学生能够方便操作。系统的主要特点和优点归纳如下：
（1）本系统用的移置性和针对性都比较高，因为针对性高可以提供更好的服务而移置性可以在多个系统上运行，更给客户带来了极大的方便。
（2）该学科竞赛管理系统内容全面，管理方便可以及时的全面的处理各种错误，异常，这样避免了很多因客户的马虎操作而出现的失误，其操作方便，会员界面友好，能够上网的人都可以很好的进行操作。
经过对上述的测试结果分析，所有基本功能齐全，操作简单，系统运行性能良好，系统安全可靠，能促进学科竞赛管理系统的发展，发展前景广阔。
结 论
本系统通过对java和Mysql数据库的简介，从硬件和软件两反面说明了学科竞赛管理系统的可行性，本文结论及研究成果如下：实现了java与Mysql相结合构建的学科竞赛管理系统，网站可以响应式展示。通过本次学科竞赛管理系统的研究与实现，我感到学海无涯，学习是没有终点的，而且实践出真知，只有多动手才能尽快掌握它，经验对系统的开发非常重要，经验不足，就难免会有许多考虑不周之处。比如要有美观的界面，更完善的功能，才能吸引更多的用户。
由于在此之前对于java知识没有深入了解，所以从一开始就碰到许多困难，例如一开始的页面显示不规范、数据库连接有问题已经无法实现参数的传递等等，不过通过在网上寻找有关资料以及同学的帮助下最后都得到了解决，在此过程中，我不仅学到了很多知识，也提高了自己解决问题的能力，尤其是学会如何从大量的信息中筛选出所需有用的信息，同时我更加深刻的体会到了，虽然书本上的大部分知识都是有价值，正确的，但实际上每个人编程的思路和对数据处理的方法、思想都是不同的，这就要求我们一定要通过实践才能找到解决问题的方案。在此次毕业设计活动中，我不断的提高了自己，也得到了宝贵的经验，我相信这些对我以后的发展都会有很大帮助。
通过这次学科竞赛管理系统的开发，我参考了很多相关系统的例子，取长补短，吸取了其他系统的长处，逐步对该系统进行了完善，但是该系统还是有很多的不足之处，有待以后进一步学习。
实践证明，学科竞赛管理系统有着非常好的发展前景，经过测试运行，系统各项功能都十分完善，界面漂亮，使用方便，操作容易，在技术理论上已经成熟。
