1 Introduction
1.1 Background of topic selection
Since the development of network technology and computer technology, they already have a profound theoretical foundation and have been fully used in reality, especially the software based on computer operation has attracted the attention of all walks of life. Computer software can set different functions according to the business characteristics and management needs of different industries, which can meet the actual operation requirements of various industries. Its fast and convenient information processing mode can already free information managers from tedious work. Easy maintenance and security of data can be realized. In addition, people have entered the information age, so the promotion and management of information is very important. Therefore, the information management mode is also the current management trend. For fixed asset information management, if the old method is still used, its competitiveness in the industry will be affected, and it will be easily eliminated by the times. Therefore, it is necessary to computerize and systematize fixed asset information management. Designing and developing a fixed asset management system will not only save manpower and management costs, but also safely save a huge amount of data. It does not take a lot of time to maintain and retrieve fixed asset information, which is very convenient.
1.2 Significance of topic selection
In the actual application of the fixed asset management system, it is also helpful to improve the overall quality of the administrator. Because the fixed asset management system not only reduces the workload of fixed asset information managers, but also allows them to use the time saved to enrich themselves and improve their personal capabilities, so that they can give full play to the services provided by the fixed asset management system. While allowing the fixed asset management system to display data information, it can also quickly complete data processing and improve service levels. Moreover, the cost of investment in the development of the fixed asset management system is low, but in the later application, it will generate a lot of benefits, especially when the fixed asset management system is in high-load operation, it can also ensure the quality and data security of data processing. The optimization of the work process can save the manpower and capital invested in the traditional mode, thereby reducing the cost of information management. In addition, while the fixed asset management system standardizes the fixed asset information, it can also detect wrong data in a timely manner through the validity rules of data input, so that the data entry can achieve the purpose of accuracy, thereby improving the data provided by the fixed asset management system. Reliability, to minimize the error rate of system data.
1.3 Research content
To describe the system according to the common process of designing and developing a system, the system can be divided into analysis phase, design phase, implementation phase, and testing phase. Therefore, when writing the description document of the system, describe the content of the system according to the stage of the system.

System testing: This is to test the compiled system. Including functional testing and other content to make an introduction.
2 System Development Technology
This part mainly introduces the technology used in this system, including the tools used, programming language and so on.
2.1 Java language
The Java language has been used for more than 25 years since 1995, and it still has a large market share in software development. Back then, Sun invented Java to develop a cross-platform high-level programming language, allowing program developers to focus on the program development process without paying attention to which platform the server belongs to, because the cross-platform feature makes the language develop rapidly. The development of Java has absorbed the advantages of languages such as C++, because new things generally solve some pain points of old things. Although Java also has many shortcomings, it is at least a development direction. Learning Java does not require too many concepts of pointers, nor does it need to learn too complicated data structure theories, such as stack concepts, unless some special industries have strict requirements for these, generally developing programs in Java does not need to consider various various data structures. Because Java is a strongly typed language, various corresponding types have been defined for various data. Java defines two types of data types, one is the basic type, which contains 8 basic attributes, and the other is the wrapper class. There is a clear distinction between the basic class and the wrapper class in terms of fundamental definitions, and the computer operation will also have obvious differences. If you use it wrong, it will cause compilation errors and affect the running effect. The various advantages of Java only need to be done step by step. You can use it for learning.
2.2 SSM framework
The framework technology mainly used in the application program developed in this project is SSM, which is the abbreviation of a set of frameworks in the Java language. At present, there are two main branches in the Java language. One is to focus on the Java language. After learning the basics of Java, you will There are many Java advanced frameworks to learn, mainly for the development and design of the application background, and on the other hand, to switch to learn the Android language, mainly for the front-end design of Android, although it is also the Java language, but mainly to learn the Android platform Various architectures and frameworks too. But regardless of the front-end application, the SSM framework is mainly a collection of mainstream frameworks developed for the server side. Aiming at the bloat and cumbersome configuration of the traditional SSH framework, both development and secondary development will cause a lot of waste of time, and the learning above cannot be effectively connected. It is necessary to adapt to various designs of the framework, and the framework design is relatively rigid. Error-prone. The SSM framework is currently the most popular. It bid farewell to the cumbersome configuration, makes the configuration more flexible, and makes the data operation more convenient. It feels very appropriate to choose the SSM framework for development.
2.3 MYSQL database
The relational database design, the design of the database field type and the design of the field length, all the time affect the operation efficiency of a large number of data operations after the subsequent program development. Relational databases have explanations for different field types. Based on the application development required by the subject, finding the most suitable relational database is basically considered. Relational databases have been developed for decades. Survival of the fittest leads to the fact that there are not many relational databases that still exist, and they can basically meet the functional needs of applications. Therefore, it is necessary to consider databases from other aspects. choose. From the perspective of installation and maintenance, the SQL Server database has several G installation packages, and many unnecessary functions will be installed during the installation process, which consumes a lot of resources. The Oracle database is not smaller than the SQL Server installation package, and there will be many problems in the installation. For the needs of the project, it is not necessary to be so troublesome, and the installation also requires various activations. Only the MySQL database is completely suitable, and the installation package is tens of megabytes in size. , it is not stressful to run. After all, there are many other useful things on the development computer, and it is completely free, so I chose the MySQL database as the preferred database.
3 System Analysis
Although this part is at the beginning of the development process, it plays an important role in the subsequent design and implementation, because the quality of the system analysis results will directly affect the development of the subsequent links.
3.1 Feasibility study
There are many factors that affect system development. For example, the development cost is high and it is not suitable for development, or the development time exceeds expectations and it is not suitable for development. Therefore, before formally making a development decision, study the feasibility of the system, and demonstrate whether the system can be developed from the perspectives of economy, time, and operation.
3.1.1 Economic feasibility
The fixed asset management system can simplify the workflow, provide information processing functions, and save data for a long time. It consumes less time in later data query and editing, improves the efficiency of information management, and brings considerable benefits. For the development of this system, no matter the computer needed for development or the development tools, the investment cost is very low. The computer is the computer in the computer room, and the development tools are downloaded and installed from the Internet, and no fees are charged.
3.1.2 Time Feasibility
The fixed asset management system is a work of my final project. The college also fully reserved the production time, and arranged corresponding tasks in each time period. Therefore, it is possible to carry out work on this system according to this schedule. Design is done.
3.1.3 Operation Feasibility
With the popularity of computers, many people can operate computers independently. This system runs on a computer equipped with a running environment. Its functions are simple and save a lot of cumbersome operation logic. Users can directly enter the functional operation area through page navigation, so anyone who knows a little bit about computers can easily Complete the use of the system.
In summary, the system can carry out the next work.
3.2 System performance analysis
In order to reduce the error rate of the system in actual use, it is necessary to analyze the performance of the system. Common indicators that can evaluate system performance include security, usability, and robustness.
3.2.1 Ease of use of the system
The information and services provided by the system have specific user groups. Therefore, users prefer an easy-to-use system to an inconvenient one. So it is very important that the system is easy to use.
3.2.2 System Robustness
In the process of interacting with the user, the system should have a corresponding feedback mechanism to deal with the user's misoperation behavior, instead of entering a system crash state. There are many functions set up in the system. When an abnormal situation occurs in a certain function of the system, other functions of the system can still be used by users. This is the embodiment of the robustness of the system.
3.2.3 System security
The data stored in the system are relatively important system resources. Once these resources are leaked, not only will there be property losses, but many customers will also be lost. Therefore, the data in the system must be in a safe environment at all times, so measures need to be taken to ensure data security, such as setting the login function, using security verification technology to guide conditional users to enter the specified page, and let non-conditional users stay on the login page. Unable to access the system.
3.3 System flow analysis
The idea of software development and design runs through this system, and its development process is shown in the figure below. In the early stage, functional analysis, functional design, and the design of the system's back-end support database are required. The designed system is implemented using coding technology, and then tested and improved.
Figure 3.1 System Development Flowchart
The premise of the visitor's operating system is that identity verification is required, and the setting of the login function is to guide the users of the system into the background operation area and keep out the users who are not the system. Its process is shown in the figure below.
Figure 3.2 Login flow chart
3.4 System function analysis
After clarifying the purpose of the system and the target user group of the system, the functions of the system can be set, the requirements of the research users for the functions can be obtained, and the functions of the system can be obtained by analyzing and summarizing similar systems in the market.
The fixed asset management system has set administrator rights, and its use case diagram is shown in the figure below. After the administrator logs in to his background, he can manage assets, asset depreciation, asset maintenance, asset scrapping and other information.
Figure 3.4 Administrator use case diagram
The fixed asset management system has set employee permissions, and the use case diagram is shown in the figure below. Employees query assets, query asset depreciation, asset maintenance, asset retirement information.
Figure 3.5 Employee Use Case Diagram
At present, there are many types of systems. Judging from the content presented by the system, the types of systems include social, business, government, and news. Then, among the many types of systems, the primary task of system design is to first clarify the type of system to be designed, and then specify the user group, functions, etc. of the system on this basis, and design a system with unique experience and vision based on this information . Only in this way can the system be more distinctive, and it can also leave a deep impression on users among many similar systems.
4.1 System Objectives
In terms of function formulation, the system strictly refers to the requirements of users, but when designing this system, it must also meet the design requirements of easy operation and convenient use. Therefore, to design a system that is standardized and meets user needs, the following system goals must be achieved.
The first system goal: the operation mode between the user and the system is based on man-machine dialogue, and the design of the visual interface is not only beautiful, but also friendly. All kinds of information provided by the visual interface meet the requirements of accuracy and reliability, and can be viewed flexibly by users.
The second system goal: the data generated by the interaction between the user and the system must be stored in the database in a strict and standardized manner, and the data security must be ensured whether it is searched and managed by the management personnel in the later stage.
The third system goal: to realize the functions required by users. Complete the design and implementation of the fixed asset management system according to the functional requirements obtained from the user survey.
The fourth system goal: In the necessary link, check the data registered by the user, including the length of the data, and the type of data input, etc., and timely feedback when errors are found, and guide the user to standardize the registration data. Common data verification includes password modification, registration and login, and user information filling.
The fifth system goal: To design and develop this system, we need to do our best. In addition to the characteristics of easy operation of the system, it is also required that the system is easy to maintain during later use, so that the system has the characteristics of easy maintenance.
The sixth system goal: when the system is delivered to users, it can achieve the goal of stable operation. In addition, the system is safe and meets the requirements of reliability, so users can use it with confidence.
4.2 Functional structure design
The function analysis done above is only a general function of the system, and this part needs to carry out the detailed design of each module on this basis.
The detailed functions of the designed administrator are shown in the figure below. After the administrator logs in to his background, he can manage assets, asset depreciation, asset maintenance, asset scrapping and other information.
Figure 4.1 Administrator function structure diagram
The detailed functions of the designed employees are shown in the figure below. Employees query assets, query asset depreciation, asset maintenance, and asset retirement information.
Figure 4.2 Employee function structure diagram
4.3 Database design
Compared with non-relational databases, the most widely used and easy-to-maintain databases in the market are relational databases. This database is mainly based on the relational model to organize data information. That is, the common two-dimensional table model. It can be said that the relationship between two-dimensional tables and two-dimensional tables constitutes a relational database.
4.3.1 Database ER Diagram
In order to better save the data generated by the fixed asset management system, it is necessary to establish the ER model in the database design phase and complete the creation of the table structure in the database. The main reasons for the design of the database are as follows:
The first point: prevent code redundancy;
The second point: prevent excessive memory consumption;
The third point: improve the overall performance of the database to facilitate program development and data update;
The fourth point: to ensure the integrity of the data;
The content of this part is mainly to establish the ER model of this system. It is necessary to collect data first, and then analyze the needs of users according to the idea of database implementation. During this period, it is necessary to identify entities, attributes, and relationships to draw the ER model. Well prepared. At the same time, in the drawing, we must also pay attention to the drawing specifications and pay attention to the correct use of each symbol.
(1) The properties of the designed asset depreciation entity are shown in the figure below.
Figure 4.4 Asset depreciation entity attribute diagram
(2) The attributes of the designed administrator entity are shown in the figure below.
Figure 4.5 Administrator entity property diagram
(3) The attributes of the designed employee entity are shown in the figure below.
Figure 4.6 Employee Entity Attribute Diagram
(4) The properties of the designed asset maintenance entity are shown in the figure below.
Figure 4.7 Asset Maintenance Entity Attribute Diagram
(5) The relationship between the designed entities is shown in the figure below.
Figure 4.8 ER diagram of relationship between entities
4. 3 .2 Database table structure
In order to design a database with reasonable structure and excellent performance, three paradigms need to be followed when designing the database:
First normal form: ensure that the field values represented by each column in the data table can no longer be decomposed;
The second normal form: on the basis of satisfying the first normal form, let each column in the data table be related to the primary key;
Third normal form: On the basis of satisfying the second normal form, ensure that each column of data is directly related to the primary key, not indirectly.
It can be seen from the above statement that these three paradigms are differentiated in terms of levels. The lowest level is the first normal form, the highest level is the third normal form, and the one that tends to be in the middle is the second normal form. In short, database design is carried out according to these three paradigms, which can simplify the design process and reduce data redundancy, which is also very helpful for improving the efficiency of data retrieval.

6系统测试
这部分内容主要是把前期编码完成的系统，当成是计算机系统的一部分，并结合一些数据，计算机硬件和支持的软件进行集成测试和确认测试。之所以要进行最后的测试步骤，原因在于检查制作的系统与需求说明书的比较中，存在的差异问题。进一步确认制作的系统在功能与性能上跟需求说明书当中的要求相符。
6.1 系统测试的类型
检测系统是否合格，需要用到很多的测试类型。接下来就对这部分内容进行描述。
功能测试：这是系统测试中，首先进行的测试内容，其属于黑盒测试。主要检验制作的系统与需求说明文档的相符程度，还有它们之间存在的差异问题。

6.4 测试结果分析
固定资产管理系统经过了编码阶段的单元测试，和最后的系统整体测试等测试后，对于用户要求的功能，本系统都进行了实现，各个模块都运行正常。在面对一些故障性问题时，本系统也有相应的应对办法，并且本系统可以保持24小时正常运转。因此，固定资产管理系统可以交付用户使用。
结 论
固定资产管理系统的开发设计并不是一件轻松事，因为毕设制作都是依照一定流程进行的。最开始是选择题目，然后通过各种方式查阅资料，以及对使用用户的需求进行调研，确定本系统的功能，为了降低系统编码的出错率，在设计阶段也需要下功夫，认真设计功能模块，使用大学所学的数据库知识，设计数据库。这样一来，对系统编码时，就会根据设计方案进行。编码完成，进行测试就能对合格的系统进行验收了。
借助身边同学还有导师提供的帮助，本人也顺利完成本系统的制作工作。对固定资产管理系统的分析与总结，发现固定资产管理系统具有如下特点：
（1）固定资产管理系统有着详细的功能设计，所以编码时，基本依照设计的功能进行开发，因此具备较完善的功能；
（2）固定资产管理系统在界面设计与布局时，参考了很多系统的界面设计风格，也从图书馆查阅了关于系统界面设计方面的资料，并把对本系统有用的知识做好笔记，有了这些知识积累，所以我在开发系统时，注重页面文字的排版，以及精确定位各页面元素，合理使用颜色搭配技巧，让本系统在不影响浏览效果的同时，让访问者产生一种简洁干净的视觉效果；
（3）固定资产管理系统为了让用户易于使用，在能够直观表达系统内容的同时，也把页面的导航放在了页面中最关键的位置，这个位置也是充分考虑了用户的浏览习惯。所以用户操作系统，可以在短时间内找到需要的内容。
由于本人并不是专门从事开发工作的技术人员，目前在校学习的开发类知识处于初级阶段，只是对开发类技术有着简单了解和使用，加上日常完成的作业，也只是局限在某个系统的某个功能模块上，因此，完成一个功能完善的整个系统，对于我来说，还是有一定的压力。所以这也确定了我开发的系统具有缺陷。
（1）对于固定资产管理系统的编码并没有完全依照编码规范，整个系统存在代码冗余的缺陷；
（2）固定资产管理系统在数据输入上，对数据有效性检测还不够严格；
（3）对固定资产管理系统的误操作提示，只是对部分功能进行了设计，还有很多功能都没有设计报错提示。
综上所述，本人仍需花费时间去学习编程知识，在后期，我将会学习代码模块化，将一些通用的函数，变量等进行单独设置，然后直接在需要的页面上进行调用，这样可以降低代码冗余率，同时也会多学习针对程序易出错地方的解决方案等知识。学习这些知识除了完善本系统之外，也是弥补自身编程能力不足的缺陷。

致 谢
伴随着毕设项目的制作完成，也就意味着我们即将离开校园。回想几年的大学时光，不由得想起身边常伴的同学，授课的老师，还有毕设指导的老师们。
大学这几年，身边的同学为我提供了很多的帮助，不管是生活上，还是学习上，每次遇到问题，这些同学们都会耐心解答，有时为了避免我再次犯错，他们也会时不时提醒我。本次毕设制作期间，这些老同学也是互相分享开发经验，还有文档编写的技巧，从开题报告，还有任务书以及最后的论文等文档上，大家都是互相提出建议，互相参考一些编写经验和技巧。如此，我们才会进展得比较顺利。此刻，真心感谢这些老同学！
唯一不能忘记的是导师，平均每个导师都带了很多个毕业生，所以能够想象他们非常忙，因为一到毕业季，他们需要指导学生们毕业，还需要正常授课。作为本届毕业生，我也能够体会导师的辛苦和不容易。毕设制作的环节有很多，但是我的导师在进行的每个环节都严格要求我认真努力对待本项目，也对我编程技术上提出了很多至关重要的建议，还对一些比较细微但是也比较关键的部分向我进行了多次强调，让我少走弯路，可以如期实现本系统。此刻，真心感谢导师！
校园里的授课老师不仅有本专业的老师，也有其他专业的老师们，他们都教过我们课程，向我们传授知识，有了这些知识积累，我在本次毕设制作中，才知道有些问题该如何运用知识处理，此刻，感谢那些授课老师。
最后时刻，我要感谢校园，祝愿校园更加强大！
