1.1 Background of the topic
Since the development of the Internet, both its theory and technology have matured, and it has widely participated in all aspects of society. It allows information to be disseminated through the Internet, and combined with information management tools, it can provide good services to people. Therefore, various industries, especially larger enterprises and schools, have begun to use the Internet and software tools to manage information, disseminate information, share information, etc., in order to enhance their own strength, improve their competitiveness in the same industry, and from Obtain development opportunities in various fierce competitions. In view of the chaotic information management of graduation project projects, high error rates, poor information security, high labor intensity, time-consuming and labor-intensive problems, after analysis and consideration, under the current circumstances, a modern management tool such as a graduation project management system can be introduced. , this tool is the best solution to solve the above problems. It can not only complete information processing in real time, but also shorten the graduation project project information management process, making it systematic and standardized. At the same time, it can also reduce the workload and save the manpower and funds required for information management of graduation project projects. Therefore, the graduation project project management system is an indispensable tool in the information management process, and it is very important for managers.
1. 2 Significance of the topic
Nowadays, there are more and more types of information, and the capacity of information is also becoming larger and larger. This is a sign of the information age. In recent years, computer science has been developing faster and faster, and software development technology has become more and more mature. Therefore, in every field of life, as long as there is information management, there is almost a shadow of computers. It can be said that many industries have Use computers to manage information. Compared with manual operations, computerized information processing has many advantages such as strong confidentiality, high efficiency, large storage space, and low cost.

Chapter 2 Development Environment and Technology
The coding implementation of the graduation project management system requires the establishment of a certain environment and the use of corresponding technologies. The following content is an introduction to the technologies and tools used in the graduation project management system.
2. 1 MYSQL database
The application developed in this project is unpredictable in data operations and changes frequently. There is no way to directly write the data in the document. This is not only unsafe, but also cannot realize the functions of the application. If you want to be able to realize the data storage functions required by your application, you cannot avoid choosing professional database storage software. Basically, the functions implemented by the application are not too complicated and can be implemented by any relational database software on the market. Based on my own learning progress and operating habits, Oracle database is suitable, but the installation software required is large, and many unnecessary functions are turned on, which consumes computer resources, so I did not choose Oracle database. , and although I have learned SQL Server database, problems often occur during installation because there may be other software on the computer. If the installation problem is not solved, you need to reinstall the operating system. This will affect the existing software. Another waste of time. There is only a MySQL database. The installation package is small, the installation speed is fast, and the operation is simple. Even if there is an installation problem, it can be easily solved. There is no need to reinstall the operating system, and it does not affect other software running on the computer. It consumes less resources. The most important thing is that it has great functions. This aspect completely meets the design needs, so the MySQL database was finally selected as the database needed for application software development.
2. 2 JSP technology
At the beginning of the rise of dynamic websites, Java, as a high-level programming language, naturally would not give up the cake in this field. Sun introduced Servlet as a technical standard for outputting dynamic websites. Although it was not very popular among programmers at the time, there were not many choices at the beginning. In the following months, the PHP language came out. Regardless of performance and efficiency, at least It distinguishes between dynamic code blocks and static code blocks required for writing web pages, which greatly improves writing efficiency and readability efficiency. Therefore, many Java programmers and junior programmers who have just entered the industry have chosen the PHP language as their career. Development direction, in order to maintain the status of Java language in high-level programming languages and prevent PHP from continuing to take away market share, Sun Company and the Apache Foundation developed a new technical standard for Java dynamic web pages. This is JSP technology. JSP absorbs all the advantages of PHP language in page writing, but backed by the huge backend of Java EE, it can also realize many functions that can be achieved through Java components. Those components can be directly referenced on the JSP page, making JSP more Strong and rich. It ensures the vertical and sustainable development of Java technology, and finally has a firm foothold in the field of dynamic website development. Other PHP developers can quickly transfer to JSP for development, regardless of the development of some special components or functions, and only develop from dynamic pages. In terms of development, it has completely realized the almost cost-free conversion of PHP programs and JSP programs, and JSP technology has developed in this way.
2.3 SSM framework
SSM framework is not the name of a framework, but the acronym of three frameworks, namely Spring framework, SpringMVC framework, and MyBatis framework. It is currently the preferred framework for learning among Java developers.
The Spring framework inherits the advantages of the JavaEE and EJB frameworks, removes bloated configurations in terms of dependency injection, simplifies the amount of code and improves code quality in terms of aspect-oriented aspects. Dependency annotations are configured so that all dependencies can be automatically configured and found through the program, reducing the amount of code writing and improving code readability.
The SpringMVC framework and Spring belong to the same company and can be reused in the underlying code structure. However, the main function is to filter data submission requests and return data. It is not limited to JSP technology on the page, but can also be other technology, a collection of technologies that are easier to develop on a large scale.
The MyBatis framework abandons the bloated configuration of the Hibernate framework. Sometimes when the Hibernate framework business is more complex, the amount of code increases, performance decreases, and the underlying database statements cannot be optimized. The MyBatis framework effectively solves this aspect. You can use Java statements optimize database operation statements, making the code simpler and more efficient. It can also produce some modular codes and solve entity mapping operations that easily occur during the development process.
Chapter 3 System Analysis
Facing the system that is about to be developed, it is necessary to conduct advance analysis. This is also a necessary part of the development process. Usually during system analysis, the main content involved includes system development feasibility issues, analysis of system functions and performance, and other issues.
3.1 Feasibility analysis
Before formally investing in a project that needs to be constructed, there is a critical step that is indispensable, and that is feasibility analysis. It mainly evaluates the feasibility of the system from the current technology, economic and other perspectives. This scientific method is often used to demonstrate the project in investment decisions.
3.1.1 Technical feasibility
At present, system development technology has matured, and through the computer network, you can obtain the usage of development tools and standardized modular codes. This knowledge can help developers successfully complete the coding work of this system.
3.1.2 Economic feasibility
The software environment that needs to be configured during the development of this system can be downloaded and installed for free through the official development website. The hardware equipment that needs to be configured does not need to have high performance. Usually computers in Internet cafes or computers in school computer rooms meet the requirements. Therefore, from economic considerations, it is feasible to develop a graduation project management system.
3.1.3 Operational feasibility
The graduation project project management system is developed according to user usage habits. The designed interface is unified and has excellent navigation functions. Therefore, anyone who can simply operate a computer can operate the graduation project project management system without any stress.
In short, from the above argument, this system can be developed.
3. 2 System process
Tools such as flow charts can intuitively reflect the internal operating logic of the system and help users better understand the system.
3. 2.1 Operation process
Visitors are required to provide verification information to enter this system. Only qualified visitors can obtain access qualifications. The specific operation process is shown in the figure below. The visitor fills in the information accurately according to the information items set on the login interface. After the information is verified, the visitor can enter the designated page to enjoy the services provided by this system and read the relevant information of this system.
Figure 3.1 Operation flow chart
3. 2. 2 Login process
The login module of this system, its internal process is shown in the figure below. It mainly judges the verification information provided by the people who access the system one by one. The system will give prompts for incorrect information entered, such as prompts for incorrect account numbers or mismatched passwords. In short, if all the information filled in on the login page meets the requirements, the visitor will log in successfully.
Figure 3.2 Login flow chart
3. 2.3 Deletion of information process
After regular use, this system will generate a lot of information that loses value. Therefore, it is necessary to clean up the data in time to free up system space. When cleaning these data, the corresponding process is shown in the figure below. First select the data to be cleaned, and repeatedly confirm the data that needs to be cleaned to prevent operators from accidentally deleting it. Deleted data will not appear in the system.
Figure 3.3 Deletion information flow chart
3. 2.4 Add information process
This system is mainly used to display information and provide services. Among them, the data adding function is one of the services. The specific process is shown in the figure below. Let the operator enter the data on the page where the information is added. After the data is submitted for verification, it will be displayed on the system designated page.
Figure 3.4 Add information flow chart
3.3 Performance requirements _
Conducting demand analysis includes formulating functions based on actual user needs, and also covers performance demand analysis of the system to be designed. Therefore, when analyzing a system, on the one hand, the function of the system must be analyzed, and on the other hand, the performance of the system must also be analyzed. After all, designing and developing a system with good performance can ensure the quality and reliability of the system.
Next, the performance of the system will be analyzed from the aspects of interface friendliness, system time characteristics, system reliability, etc.
(1) Time characteristic requirements: The system has time requirements for processing data, which is also the time characteristic of the system. Usually the data processing time is analyzed, the response time of user requests is also set, and the range of values that the system can deviate from when running at full load needs to be analyzed and determined in advance.
(2) Interface friendliness: In addition to considering user needs in terms of functionality, the design of the human-computer interaction interface also needs to consider the user's usage habits, including interface layout, interface tone selection and color matching, etc. Try to ensure that users can operate the system independently after receiving simple training.
(3) System reliability: For beginners, one problem that easily arises is that the system designed and developed may crash due to human misoperation, and some may also cause the computer to crash. This phenomenon also shows that this system with low fault tolerance is unreliable. It cannot be used as a system for processing information in daily life. At present, system development must ensure reliability, and modular and structured design concepts should also be taken into consideration during design. If you encounter a system that has strict timeliness requirements, you will also need to take other measures, such as a dual-machine system and a disk array. There is also a reliable system, which also has requirements for the power supply capability of the equipment.
3.4 Functional requirements
Different systems provide different services and have different corresponding functions. Therefore, before starting the system, it is necessary to clarify its purpose and determine its functions. From this, each task can be carried out.
After analysis of the graduation project project management system, it was determined that the role of the administrator needs to be set, and its operating functions are displayed through a use case diagram (see the figure below). The administrator manages the design topics, voting records, topic selection information and announcements.
Figure 3.5 Administrator use case diagram
After analysis of the graduation project project management system, it was determined that it needs to set up the role of teachers, and its operational functions are displayed through use case diagrams (see the figure below). Teachers vote on design topics, review and manage user topic selection information.
Figure 3.6 Teacher use case diagram
After analysis of the graduation project project management system, it was determined that the user roles need to be set, and its operating functions are displayed through use case diagrams (see the figure below). Users select design topics, check the review status of topic selections, and manage topic selection information.
Figure 3.7 User use case diagram
Chapter 4 System Design
A successfully designed system must be rich in content and user-friendly in terms of system appearance or system functions. Therefore, in order to enhance the value of the system, attract more visitors to the system, and allow visiting users to spend more time on the system, it means that the system is designed to be more professional.
4.1 Design principles
This system needs to follow certain design principles during the design process. The purpose is to ensure that the developed system has high quality, complete functions, and is convenient and simple to operate, so that it can meet the user's requirements to the greatest extent. In addition to the basic principles of easy operation, the system design principles also include the principles of safety and accuracy.
The first design principle: the principle of ease of operation. The functions designed for this system must be complete and complete. When coding, the interfaces designed must be friendly. Once users use this system, they must be able to easily get started and operate the system to process data. time, it must be convenient. In addition, some necessary prompts need to be designed to guide users to operate the system.
The second design principle: the security principle. This system needs to authenticate each visitor in the login module. The system will judge based on the information entered by the visitor, use the security verification code written in advance for data comparison, and guide the successful matching. Visitors enter the specified operation interface. This prevents irrelevant visitors from stealing system data.
The third design principle: the principle of accuracy. In order to ensure that the data registered by users is correct, a data error correction mechanism needs to be designed in advance so that users can carefully check the registered error information through the system's error prompts and correct the errors in a timely manner. , fill in the correct information. For example, when setting a password, it is required that the length of the password cannot be less than 6 characters, and the data type cannot be all numbers, etc. can be standardized.
4.2 Functional structure design
Based on the administrator functions analyzed previously, the next design work is carried out, and the designed administrator structure diagram is finally displayed (see the figure below). The administrator manages the design topics, voting records, topic selection information and announcements.
Figure 4.1 Administrator function structure diagram
Based on the teacher functions analyzed previously, the next design work is carried out, and the designed teacher structure diagram is finally displayed (see the figure below). Teachers vote on design topics, review and manage user topic selection information.
Figure 4.2 Teacher functional structure diagram
Based on the user functions analyzed previously, proceed with the next design work and finally display the designed user structure diagram (see the figure below). Users select design topics, check the review status of topic selections, and manage topic selection information.
Figure 4.3 User function structure diagram
4.3 Database design
Developing a system also requires designing the database in advance. The database here is a collection of related data, and the data stored together is also organized in a certain way. At present, the database can serve a variety of applications because it has the best storage method and the advantage of low data redundancy rate. Although the database provides information storage services for the program, it can also maintain a high degree of independence from the program. All in all, the database has experienced a long period of development. From being unknown at the beginning to being well known now, its related technologies have become more mature and it also has a solid theoretical foundation.
4.3.1 Database conceptual design
This part of the content needs to be completed with the help of database relationship diagrams, and also requires the use of tools specifically designed to draw database relationship diagrams. For example, Visio tools can design ER diagrams (database relationship diagrams). Designing a database also needs to follow the design process. First, the entities must be determined according to the requirements, the characteristics of the entities must be analyzed, and the relationships between entities must be determined. Finally, the ER model representation method is used to draw the ER diagram of the system. Regardless of whether you use Edraw software or Visio tools, the representation symbols for ER models are the same. Generally, rectangles represent entities, the relationships between entities are represented by diamond symbols, and the attributes of entities, that is, the characteristics of entities, are represented by symbolic ellipses. Finally use straight lines to connect symbols such as rectangles, rhombuses and ovals. Next, start drawing the ER diagram of this system.
4.3.2 Database physical design
This database is a relational database, so the structural design of the two-dimensional table is also critical. After all, the two-dimensional tabular model is the relational model in the relational database. Some commonly used concepts in relational models also need to be understood before you can design the relational model. The following is a brief introduction to the meanings of common concepts such as relationships, tuples, attributes, domains, keywords, etc.
Relationship: A relationship is a data table in the database. Each data table has a name, that is, each relationship also has a name, which is the name of the data table;
Tuple: A tuple is a row of records in the data table;
Attribute: An attribute is a field in the data table, that is, a column in the data table;
Domain: Domain is to limit the values of attributes in the data table;
Keyword: The keyword is the primary key in the data table;
After understanding the common concepts of table structure design, you need to use the ER model drawn previously to complete the design of the table structure, create data tables in the database, and name each data table. The design results are presented below in tabular form.

6.1.2 修改密码功能测试
这个功能的设置也是出于对系统的保护，让操作人员的密码可以一直变化，减少泄露的几率。测试的数据见下表。通过验证旧密码，确认操作者是本人，然后开始对新密码进行登记。一般修改完密码后，需要再次登录。

6.2 测试结果
经过测试，从毕业设计项目管理系统功能的角度来看，本系统各个功能在符合用户要求的情况下，也能保持运行正常。从毕业设计项目管理系统性能的角度来看，本系统可以保持24小时不间断运行，而且面对用户的误操作行为，有提前设置的错误反馈机制应对，另外，本系统界面布局考虑用户阅读习惯，可以让用户短时间内获取需要的内容。总之，本系统可以投入生产，帮助用户解决实际问题，发挥其应用价值。
结 论
采用Java+Mysql的方式设计制作的毕业设计项目管理系统，在功能上可以满足管理人员对于信息的管理需求；在界面的设计上，尽最大努力用自身的美工知识做到界面美观简洁。在操作方面上，让系统可以方便操作，同时对用户常见的误操作行为进行分析总结，并尽力在系统中避免同样的由于用户的误操作所带来的错误现象。
作为毕业设计，分配给本系统的设计与制作时间还是不足的，所以，毕业设计项目管理系统还有许多需要完善的地方。
第一个就是本系统的编程代码问题，各个程序文件的代码存在冗余的地方非常多，导致代码不够简洁，同时对代码的注释也比较麻烦。编码期间，对于很多页面可以共享的函数与方法都没有单独列出来，而是在需要用到函数和方法的页面上都重新编写了代码，通过后期的技术学习，以及对编码过程的分析总结，发现可以把共用的函数或方法编写在同一个页面上，在之后的页面中，需要使用此函数的页面，则可以直接调用函数，无需再编写代码了，这样可以简化代码，也能节省时间和存储空间。
第二个就是对数据库的设计不够好，在数据处理中，影响程序运行速度。因此需要对数据库的性能进行优化。通过这方面知识的学习，在某个开发技术类的博客中，发现可以用数据库连接池技术来解决数据库的性能问题，另外还需规范数据库里面的关系模式，降低数据库的冗余率，提高运行速度。
如果说平时的作业也是检查对知识的掌握情况，那么制作毕业设计，将是对自身所有知识的一个全面检测。因为系统能够制作完成则是经历了很多阶段，正如文中所展示的那样，先有可行性分析，对功能的分析，对功能的设计，对数据库的设计，对程序功能的编码实现，对完成编码程序的测试等，这些环节缺一不可，而且还都需要认真对待，大学学到的所有知识在制作系统时，才会发现不够用。所以这个项目制作，在检测自身能力的同时，也对问题分析，资料搜集，问题解决等能力进行了培养。
我通过制作本系统，熟悉了程序开发的流程，提高了对程序的编码能力，培养了独立分析与解决问题的能力；但也让我明白自身的不足之处，所以在接下来的时间，我还是要加强对技术知识的学习，去逐渐完善本系统。
制作毕设项目这段时间，忙碌又充实。从最开始选题的不知所措，到现在毕设项目完成时的淡然，两种完全不同的心境，也意味着我这段时间在不断成长。项目制作是一个很耗费时间与精力的任务，如果说仅仅依靠自己的话，那肯定达不到毕设的标准。所以，这一路走来，导师给予我的帮助也是非常大的。不管我处于哪个阶段，比如选题阶段，比如分析系统功能阶段，设计系统结构阶段，系统编码阶段等，都有导师参与指导，他提出的建议和技术上的指导让我可以更快地完成这个毕设项目。此刻，我非常感谢导师，感谢他提供的帮助。
毕设项目制作期间，我身边的同学也及时指出了我系统的错误，并帮助我完善已开发的系统，还提供了很多文档撰写的技巧，所以，我也非常庆幸能和他们一起努力制作项目，也非常感谢他们一直以来的陪伴。
大学短短几年，能够得到成长，也离不开授课老师们，他们一直在校园为广大学子传授知识，用他们毕生所学，教出一批批优秀的学生，我这几年的成熟与成长也得益于他们的教导。所以我也非常感谢校园的各位老师。
即将离开校园，回想这几年的时光，还真挺不舍。安安静静在校园走了一圈，发现我的大学校园真的很美，我也感谢学校给我们提供这么美好的学习环境，以及给了我上大学的机会。感谢母校！
