Chapter One Introduction
1.1 Research Background
This college competition information management system is a college competition information management system including administrators and students. The system must have a good and stable network environment during use. If it is used in an unstable network environment, system freezes and loading delays may occur. Therefore, the information management of college competitions in the past should also get rid of the manual management mode and use computer technology to carry out information management. Therefore, the university competition information management system designed by this system combines text and images, and can provide students with online competition registration and check competition results, which is also impossible for traditional models. After several years of practice and summary, college competition information management is developing in a deeper direction. The design of this system can improve the work efficiency of the administrator, so that students can view the competition information and register online anytime, anywhere and without restriction.
Therefore, it is very necessary to develop a high-efficiency, low-error college competition information management system. The main purpose of this system is to fully realize the digitalization of college competition information management system, so that administrators can master all modules, and students can have an intuitive understanding of competition information.

Chapter 2 Development Technology and Environment Configuration
Using java as the development language, using the current advanced springboot framework, using Eclipse as the system development tool, and MySQL as the background database, a university competition information management system was developed.
2.1 Introduction to Java language
The Java language is a complete object-oriented programming language. The idea of an object-oriented programming language is to regard objectively existing things as a type of object with state and behavior, and then find out the common state and behavior of the same type of object through an abstract method to form a model—class. Class is the core of the Java programming language and the basic abstract unit of the Java language. All kinds of things in the world are objects, which can be abstracted into classes with state and behavior. The main features of the Java language are:
Java language is a typical object-oriented. It provides classes, and classes provide object models. By using inheritance and polymorphism, code reuse can be achieved.
The Java language is safe. The biggest problem to be solved in the contemporary network environment is the security problem. Java has internal security measures to ensure the safety and integrity of the program.
The operation of the Java language is platform-independent. Java programs can run on any system, as long as the Java operating system is installed.
The Java language is multithreaded.
The Java language has memory management. Java can automatically manage memory, making good use of system resources and reducing waste.
2.2 Spring boot framework
This technology is an open source application framework of the Java platform, and its purpose is to simplify the initial construction and development process of Sping. By default, many framework usage methods are configured, and Jar packages are automatically loaded, in order to allow readers to run spring applications as quickly as possible.
The main advantages of SpinrgBoot are:
Provides a faster and broader entry experience for all spring development;
zero configuration;
Integrate the configuration of a large number of commonly used third-party libraries;
Provide ready features. Today, developers in the Java field are using SpinrgBoot, gradually becoming a leader in the development field.
2.3 MySQL environment configuration
(1) The data of this system uses MySQL, so you need to install MySQL to the specified directory. If you download the non-installed MySQL compressed package, you can directly decompress it to the specified directory. Then click on the file C:\Program Files\MySQL\bin\winMySQLadmin.exe where C:\Program Files\MySQL is the MySQL installation directory. Enter the initial student and password of winMySQLadmin (note: this is not the student and password in MySQL), and don’t worry about it. After confirming, a traffic light icon will appear in the task startup bar in the lower right corner. The red light means the service is stopped, and the green light means the service Normal, left click on this icon ->winnt->install the service to install this service, then left click on this icon ->winnt->start the service to start the MySQL service.
(2) Modify the root password of the MySQL database. Use cmd to enter the command line mode and enter the following command:
cd C:\Program Files\MySQL\bin
MySQLadmin -u root -p password 123
Press Enter and Enter password: appears, which is to enter the original password. The password was empty when it was first installed, so press Enter directly. At this time, the password of the account root in MySQL is changed to 123 and the installation is complete.
2.4 Introduction to mysql database
Using MYSQL's data independence, security and other characteristics to operate data in software projects can ensure the accuracy of data and reduce the application development time of programmers.
The feature of MYSQL is that it supports multi-threading, which can make full use of system resources conveniently, effectively improve the speed, and also provides various ways to connect to the database; MYSQL is relatively weak in function and small in scale, but the requirements of this system are not high. MYSQL can fully satisfy the use of this website.
Using MYSQL to establish a system database is not only conducive to the early integration of data processing services, but also conducive to the development of the latter two types of data expansion operations.
2.5 B/S Architecture
The B/S system can be used through a computer that can access the Internet. Its biggest advantage is that it does not need to install special software. First, the browser sends a request to the server, and then the server processes the request and returns the information to the browser. There is no need to access and calculate the data again, as long as it is responsible for displaying the data to reduce the requirements. If the client is like a "thin man", the server will become more and more "fat". The biggest difference between the B/S architecture and the C/S architecture is that the application software of the B/S system uses a web browser as a platform for interacting with students, while the C/S needs to develop a dedicated application program.
Currently, there are two popular structures of MIS system: C/S and B/S.
C/S structure system: C/S structure is the client server structure, which can send tasks to the Client and Server to make full use of the advantages of the hardware environment at both ends to reduce the communication cost of the system. The main role of the client is to handle human-computer interaction, execute client applications, collect data, and send task requests to the server. The basic role of the server is to execute the background program. It mainly responds to the client's request application. In addition, its role also includes: shared management of data service reservation storage system, communication management, file management and so on.
B/S architecture system: This network structure simplifies the client and concentrates the center of system function realization on the server. In this mode, only one browser is needed. This structure hands a lot of work to the WEB server, only requests WEB services through the browser, and then returns information according to the request.
Usually used inside the website, using C/S. The use of B/S is not limited to the case of intranet. Considering a series of requirements of this management system, the system is developed using B/S architecture.
2.6 Tomcat server
Tomcat is a small and lightweight application server. It is widely used in small and medium-sized systems and occasions where there are not many concurrent access users. It is the first choice for developing and debugging java programs. It can be considered that when the Apahce server is configured on a machine, it can be used to respond to access requests for HTML pages. Actually the Tomcat part is an extension of the Apache server, but it runs independently, so when running tomcat, it actually runs as a separate process from Apache.
Chapter 3 System Analysis and Design
3.1 Feasibility analysis
For a complete system, feasibility analysis is a must, because it is related to the survival of the system, and the significance of development is analyzed. Can this website supplement the gaps in the information management mode of offline college competitions to solve the problem? The deficiencies, etc., through the analysis of this website, not only can the workload be continuously reduced, but also the efficiency of work and management can be improved. Therefore, the development of the website can achieve greater significance and value. After the website is completed, whether it can achieve the expected effect requires a feasibility analysis. After the analysis, it is decided whether to develop the system. In the development and design of the college competition information management system, the feasibility analysis was carried out in terms of technology, economy and operation;
