Chapter One Introduction

1.1 Background and significance

System management will also be carried out through computers for overall intelligent operation. The Huagu flower science system involves a lot of management and data storage, which brings huge challenges to the work of managers. Faced with a large amount of information, Traditional management systems collect detailed information through notes. Later, computers appeared, and paper-based information was transferred to the computer through computer input software. This method is more traditional, and it is more troublesome to collect statistical information. It is also affected by time and space, so the Huagu Flower Science Popularization System was developed for this purpose; it provides users with a convenient management platform for administrators to view and maintain, and can edit and maintain device information content according to needs; for users In other words, Huagu flower and plant information can be viewed at any time. Administrators can obtain system data information without leaving home, and it can also save users a lot of time. Therefore, the development of Huagu flower science popularization system has brought great benefits to managers. It is convenient and also convenient for administrators to process user information.

This paper's Huagu flower science popularization system mainly involves programs, databases and computer technology. Covering a wide range of knowledge can greatly improve the work efficiency of system personnel.

1.2 Overview of research at home and abroad

With the continuous development of the domestic economic situation, China's Internet has entered a rare period of peak development, which has caused Chinese and foreign capitalists to turn to the Internet market. However, the unreasonable structure, shortage of personnel and the increase in market management needs in many management fields have made more people aware of Internet management.

In today's highly developed information, information management reform has become a more extensive and comprehensive trend. "Huagu Flower Science Popularization System" is based on Mysql database and implemented on the basis of springboot framework design. In order to ensure the sustainable development of China's economy, the information age is increasingly updated, and the service industry is still booming. At the same time, with the rapid development of the information society, various management systems are faced with more and more data that need to be processed. How to enable managers to query, store, manage and share effective data in the vast data ocean in a convenient and fast way? Information has important practical significance for our study, work and life. Therefore, academic circles at home and abroad have conducted in-depth and extensive research on this, and a new research field-Huagu Flower Science Popularization System was born.

1.3 Contents of the study

At present, many people still use traditional paper tools as the main tool for information management, and the application of network technology only plays a supporting role. In terms of awareness of network tools, more traditional office software is still the main tool used by people, while relatively comprehensive and professional information management software is still not understood or recognized by most people. This topic aims to realize the various functions of the Huagu flower science popularization system through label classification management and other methods, so as to achieve the management of the Huagu flower science popularization system.

The detailed introduction will be elaborated in the following six chapters:

Chapter 5, the implementation of system design, demonstrates the structure of the system through a detailed description of the system functional design.

Chapter 6: Overall test of the system to determine whether the system can be run online.

Chapter 2 Research on Key Technologies

2.1 Development technology

The front-end framework of this system uses the popular progressive JavaScript framework Vue.js. Use Vue-Router and Vuex to realize dynamic routing and global state management, Ajax to realize front-end and back-end communication, and Element UI component library to quickly prototype the page. Back-end part: Use springboot as the development framework, and integrate MyBatis, Redis and other related technologies.

2.2 MVVM pattern

MVVM is the abbreviation of Model-View-ViewModel. It is essentially an improved version of MVC. MVVM abstracts the state and behavior of the View, allowing us to separate the view UI and business logic. Of course, ViewModel has already done these things for us. It can take out the data of the Model and help handle the business logic involved in the View due to the need to display content. Microsoft's WPF brings new technical experiences, such as Silverlight, audio , video , 3D , animation ..., which results in the software UI layer being more detailed and customizable. At the same time, at the technical level, WPF also brings new features such as Binding, Dependency Property, Routed Events, Command, DataTemplate, ControlTemplate and so on. The origin of the MVVM (Model-View-ViewModel) framework is a new architectural framework that evolved from the application method of combining the MVP (Model-View-Presenter) pattern with WPF . It is based on the original MVP framework and incorporates the new features of WPF to cope with increasingly complex changes in customer needs.

2.3 MySQL database

The advancement of science and technology has brought many conveniences to daily life: classroom projectors use virtual imaging technology, and digital cameras use photoelectric detection technology. For example, the records of supermarket goods entering and leaving the warehouse require an information warehouse. This information warehouse is the database, and this time the Huagu flower science popularization system also needs the support of this technology.

The software MySQL is used because it can accept access from multiple users, and Archive etc. exist in it. It will first classify the data and then save it in tables respectively. Such special operations will improve the speed of the data management system itself and allow the database to be used flexibly. MySQL's code is public and allows others to compile and upgrade it again. This feature can reduce user costs and form a good website system when paired with appropriate software. Although it has shortcomings, in all aspects, it is the mainstream application object of users.

2.4 B/S structure

B/S (Browser/Server) is a more trouble-free architecture than its predecessor. It uses Web server to complete data transmission and exchange. You only need to download the browser as the client, and your work will be "slimmed down" without having to consider the issue of constantly installing software.

2.5 Introduction to spring boot framework

The Spring framework is an open source application framework on the Java platform that provides a container with control inversion characteristics. Although the Spring framework itself has no restrictions on the programming model, its frequent use in Java applications made it so popular that it was later used as a supplement or even a substitute for the EJB (Enterprise JavaBeans) model. The Spring framework provides a series of solutions for development, such as utilizing the core features of inversion of control and implementing inversion of control through dependency injection to implement containerization of the managed object life cycle, using aspect-oriented programming for declarative transaction management, and integration A variety of persistence technologies manage data access, provide a large number of excellent web frameworks to facilitate development, and so on. The Spring framework has the Inversion of Control (IOC) feature. IOC is designed to facilitate project maintenance and testing. It provides a method for unified configuration and management of Java objects through Java's reflection mechanism. The Spring framework uses containers to manage the life cycle of objects. The container can configure objects by scanning XML files or specific Java annotations on classes. Developers can obtain objects through dependency lookup or dependency injection. The Spring framework has an aspect-oriented programming (AOP) framework. The Spring AOP framework is based on the proxy mode and is configurable at runtime; the AOP framework mainly modularizes cross-concerns between modules. The AOP framework of the Spring framework only provides basic AOP features. Although it cannot be compared with the AspectJ framework, it can also meet basic needs through integration with AspectJ. Transaction management, remote access and other functions under the Spring framework can be realized by using Spring AOP technology. Spring's transaction management framework brings an abstraction mechanism to the Java platform that enables local and global transactions, as well as nested transactions, to work with savepoints and in almost any environment on the Java platform. Spring integrates a variety of transaction templates. The system can configure transactions through transaction templates, XML or Java annotations, and the transaction framework integrates functions such as messaging and caching. Spring's data access framework solves common difficulties developers encounter when using databases in their applications. It not only provides support for all popular data access frameworks such as Java: JDBC, iBATS/MyBATIs, Hibernate, Java Data Objects (JDO), ApacheOJB and ApacheCayne, but can also be used with Spring's transaction management to provide data access. Flexible abstraction. The Spring framework did not initially intend to build its own Web MVC framework . During the development process, its developers believed that the separation between the presentation layer and the request processing layer of the existing StrutsWeb framework, as well as between the request processing layer and the model, was not enough, so they created SpringMVC.

2.6 Vue.js main functions

Vue.js is a progressive framework for building user interfaces. Unlike other heavyweight frameworks, Vue adopts a bottom-up incremental development design. Vue's core library only focuses on the view layer, and is very easy to learn and integrate with other libraries or existing projects. Vue, on the other hand, is fully capable of driving complex single-page applications developed using single-file components and libraries supported by the Vue ecosystem.

The goal of Vue.js is to implement responsive data binding and composed view components through the simplest possible API.

Vue.js itself is not a full-featured framework - it only focuses on the view layer. Therefore it is very easy to learn and very easy to integrate with other libraries or existing projects. On the other hand, Vue.js can also power complex single-page applications when used with related tools and supporting libraries.

Chapter 3 System Analysis

3.1 System design goals

The Huagu flower science system is mainly for the convenience of users to view Huagu flower and plant information, etc., and also to better allow administrators to better store all data information and provide quick and convenient retrieval functions. Each module of the system is passed through many today's The developed system makes a reasonable analysis to determine the operability considering the user, follows the principles of system optimization developed, and undergoes comprehensive investigation and research.

Analysis of the functions to be achieved by the system. For the convenient management of the current network, the system should enable users to directly view the website homepage, communication forums, questionnaires, announcements, flower culture, flower encyclopedia, flower cultivation, flower mall, etc. on the platform homepage. , according to your own needs, you can view Huagu flower information or Huagu flower products, etc. This can not only save users' time, but also eliminate the need to query in the traditional way. Due to the time constraints of many users, it is difficult to meet the user's various needs. kind of demand. Therefore, the development of the Huagu flower science system can not only meet the needs of users, but also improve the work efficiency of administrators and reduce the original unnecessary workload.

3.2 System feasibility analysis

The development environment and configuration of the system can be installed by yourself. The system uses spring boot development tools and the relatively mature Mysql database to interact with relevant data between system users and administrators. The database is modified according to technical language and needs. Maintenance can make the system operation more stable and safe, thereby completing the development of the system.

(1) Hardware feasibility analysis

The design of Huagu Flower Science Popularization System and Information Analysis does not have any rigid requirements for the computer used. As long as the computer can be used normally for code writing and page design, it is feasible. The main requirements are for the server and the uploading of the platform after completion. The server has certain requirements. The server must be chosen with relatively high security, and then opening the system must be smooth and cannot be paused for too long; it must be cost-effective and secure.

(2) Software feasibility analysis

The entire system is developed using cloud computing. The advantages of cloud computing are the scalability of traffic and intelligent adjustment based on traffic, ensuring the security of the system and the timely backup of data information.

Therefore, we conducted a feasibility study from two aspects and it can be seen that there is no problem in the development of the system.

第六章系统测试

6.1测试定义及目的

关于系统实现的测试，英文名称是System TEST，简称ST，ST是使用完整其系统的各种功能多次、多案例、多环境测试，这是ST的简单描述。ST可以证明该功能对系统的要求是否得到满足以及是否有效。

对于系统开发的实现，不管开发过程多么努力，在系统运行的时候多少都会出现一些错误信息，所以为了系统的安全性及提高系统的使用率及给用户带来更好的体验，系统在完成之前，一定要进行一遍系统的测试，再完美的程序也会有漏洞，再细心的技术开发员也会有疏忽的时候，所以对于程序的测试是必须要做的一步。通过系统测试找到系统存在的问题，并根据问题的原因进行在线解决问题，如果找不到解决问题的办法可以进行通过咨询指导老师或者通过同学帮忙，一定将问题找出，否则将会出现更多的错误。所以程序出现错误时不可避免，系统测试虽然耗时费力，但是为了确保后期系统的长期使用，必须要进行系统测试，问题解决完成后还要再一步测试，直到没有任何问题后方可进行使用。

6.2性能测试

任何一款程序开发成功后都必须通过软件测试，它是保障软件稳定运行的前提。测试最主要的一步就是性能测试，性能测试内容如下：

(1)对于测试的速度有一定的要求，速度必须快，而且对于测试出来的错误问题一定以最快的速度进行处理解决，并且进行再次测试，保证整个系统运行的安全性。

(2)在系统测试的时候要将测试所用到的测试计划和测试报告保管好，方便后期系统的运行使用后的整体维护操作。

(3)软件测试整个过程中的聚类现象应优先考虑。

(4)对于整体系统测试，不要用自己的思想去认可整个系统，而是从公正的角度的进行对系统进行认可，是否符系统的整合应用。

6.3测试模块

测试需求	测试重点	是否达成需求	结果
用户登录	输入账号密码	需求达成	通过
用户注册	创建新的账号密码	需求达成	通过
登录失败	输入错误账号密码	需求达成	通过
修改信息	修改成功	需求达成	通过
添加信息管理	增删查改	需求达成	通过
评论管理	增删查改	需求达成	通过
回复管理	增删查改	需求达成	通过
搜索查询管理	增删查改	需求达成	通过

系统测试方面，我们通常运用的是白盒测试以及黑盒测试这两种方法。白盒测试是指在了解系统内部工作流程的前提下，可以根据需求规范验证系统内部操作是否能够正常运行的测试；而黑盒测试指的是，倘若知道了这个系统的全部功能，可以进行测试检测系统中的每一个功能是否满足正常使用。

为了方便用户使用“花谷花卉科普系统”，以及尽可能少的减少系统测试错误的发生，我们对该系统进行了相对应的测试。

对该系统的全部的功能界面进行测试，简单来说，就是我们输入一些数据并且对其进行提交，之后我们查看每个页面的反馈，检测页面的相关功能可不可以完全实现。

6.4测试结果

测试评估的结果是花谷花卉科普系统满足要求中的所有功能，处理大多数错误条件，修复大多数错误并通过测试。花谷花卉科普系统的基本功能都是可行的，不管是系统里面的功能还是界面的设计都是可值得推广宣传的。

总结

花谷花卉科普系统的整体功能模块的实现，主要是对自己在大学这几年时间所学内容的一个测试，对于系统，主要是通过现在智能化的花谷花卉科普系统进行开始系统的实现，管理员根据问题信息进行科研成果信息及留言信息管理等操作，并且可以根据需求进行数据信息的增加修改删除等操作，完美的解决了当下花谷花卉科普系统中所遇到的问题。

After a semester of implementation of the graduation project, it is nearing completion. So far, when I look back on the system development day throughout the semester, I have gained a lot. The main task of the graduation project is to establish an intelligent Huagu Flower Science Popularization System information system. It mainly uses the development tools of spring boot and Mysql database to perform corresponding operations on each functional module of the system. Finally, the system debugging results show that the system Basically can meet the functional requirements.

The development of the Huagu Flower Science Popularization System has been of great help in improving my university studies. It enables me to learn the technical aspects of computer knowledge and the communication aspects of interacting with people. It makes me realize that no matter what we do, we need to persevere and work hard. Only by trying and persisting in doing it, we Only then can you succeed and get the joy of success. If you don’t try and just think, you won’t even have a chance of success. Only by doing the actual operation will you get closer and closer to success. As the road moves forward, the future will The road is beautiful.

The implementation of the Huagu flower science popularization system is the first time I have completed the design of a management system. During the design process of the project, I overcame various difficulties, and in the face of these difficulties, I actively faced them, found ways to solve the problems, and better mastered the theoretical knowledge and hands-on practical ability, from the development of the system By the time the design was completed, I had completed a more comprehensive, complete, and secure platform management system, which also gave me a great sense of accomplishment and made me more confident in my future life.

Thanks

Time flies like an arrow, and the sun is like a boat. The immediate end of my graduation thesis also means that my four-year college life is coming to an end. Thesis writing is tedious and challenging. The guidance of the instructor, the support and encouragement of students and parents are the reasons why I persisted in completing the thesis. First of all, I would like to thank my supervisor for providing valuable opinions on the beginning, first draft, and design of the thesis. Without the teacher’s hard work and strict requirements, I would not have been able to successfully complete my thesis. Here, I would also like to thank my mother and father. I want to say many words of gratitude to you. I want to repay you through my learning achievements. I wish you health and happiness forever! Finally, I would like to thank all the teachers, classmates and friends who have helped me and spent many happy and unforgettable days. I wish you happiness forever.

Four years is hardly a short time in my long journey of life, but these short four years are the most sincere youth; the purest years; and the most beautiful university life. I will remember every bit of college and every lovely person in college.
