3.1 Technical Feasibility: Technical Background
1 System Overview
1.1 Overview
With the rapid development of society, the impact of computers is comprehensive and profound. With the continuous improvement of people's living standards, people's requirements for the management of children's vaccine reservation information in daily life are also constantly increasing, and the number of people who need children's vaccine reservations is constantly increasing, making the development of children's vaccine reservation management a necessary and urgent matter. Children's vaccine reservation management mainly uses computers to manage the information required for children's vaccine reservation management to increase user choices. It also facilitates timely query and modification of user information and timely understanding of user information. Children's vaccine appointment management brings more convenience to users. The system cooperates with the database management system software to meet the needs of users.
1.2 Significance of the topic
With the development of global informatization, people's life pace is getting faster and faster, and people pay more and more attention to the timeliness of information. Traditional media based on traditional propaganda methods have long been unable to meet people's needs for access to information and convenience. Therefore, children's vaccine appointment management has gradually become the focus of people's attention. First of all, in the management of children's vaccine appointments, the real-time and convenient nature of obtaining information online is much higher than that of traditional media. Once the system is online, no matter where in the world the user is, as long as they can connect to the Internet, they can get the information they want as soon as possible.
The application of computer technology in modern management has made computers an important tool for people to apply modern technology. It can effectively solve the problem of convenient and comprehensive acquisition of information and improve efficiency.
1.3 Main content
Children's vaccine appointment management needs to be analyzed from the aspects of functions, data processes, feasibility, operating environment, etc. The database and functions of children's vaccine appointment management were designed in detail. The main interface design and related component design are analyzed, and the specific implementation of children's vaccine appointment management is introduced.
Java technology is used to obtain data from the database and write data to the database, so that the system can directly perform various operations on the database and add dynamic content to the web page, thus realizing various basic functions required for children's vaccine appointment management.
2 System development environment
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.
2.1 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.
2.2 Introduction to JAVA
Java mainly uses CORBA technology and security model to protect data in Internet applications. It also provides full support for EJB (Enterprise JavaBeans), java servlet API, SPRINGBOOT (java server pages), and XML technology. Java is a computer programming language with three main features: encapsulation, inheritance, and polymorphism. It is widely used in enterprise web application development and mobile application development. The difference between the Java language and general compilers and literal translation is that Java first converts the source code into bytecode and then converts it into an executable file for the JVM, which can run on a variety of different JVMs. Therefore, its cross-platform nature is achieved. While this made Java very slow in its early days, it has improved as Java has developed.
2.3 Implementation method of accessing database
(1) First, introduce the basic steps of web database search on the network:
Step 1: Check the consumer’s data,
Step 2: You must establish a connection to the database;
Step 3: Search the database;
Step 4: Structure of data;
Step 5: The user's results are shown.
(2) System until my MYSQL5.0 PHP integrated development environment, such as using WAMP server is turned on, and it is easier to access the database report development environment:
A connection to the MySQL database server Mysql_connect-;
Syntax: resource mysql_connect(host, username, password);
Please select the database: mysql_select_db (the name of the database link identifier);
Close the database: mysql_close();
2.4 Two connection methods of the system to the MySQL database
Active MySQL/MySQL library, or using the ODBC interface, the MySQL database is a two-way link. Permanent and non-permanent connections.
(1) Permanent connection: The biggest advantage of a more permanent connection request is that it can be very effective for the client to stand in close contact, even better when connecting to the MySQL server. The page is drafted every time a child is connected in the process, not just at any time, only during the lifetime of the connection request to the MySQL server, once connected. This sub-process is to establish a separate connection to the server which can be permanent.
(2) Non-permanent connection: it is a short circuit. The submission goes down to the web server, the server handles the request and sends the requested page to the browser you want to send to the client, and then the connection drops. For most websites it is often efficient in relation to the connections used but in most cases it is a full time to avoid any problems and to increase the capacity the server is hosting.
2.5 MySql database
The language of Mysql is unstructured and users can work on the data. Because Mysql's language and structure are relatively simple, but its functions and amount of stored information are powerful, its speed, reliability and adaptability have attracted much attention and have been widely used. The role of Mysql database in the programming process is very extensive, bringing convenience to users for data query. The application characteristics of Mysql database: strong flexibility, powerful functions, and the language is relatively simple.
Data process analysis is primarily a repository of data storage, which is performed on a computer rather than a real-life repository. Database management mainly includes data storage, modification and addition, and the establishment of data tables. 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. Due to the powerful functions of the database, the development of this system mainly uses Mysql for data management.
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.
3.1 Technical Feasibility: Technical Background
Children's vaccine appointment management is developed and used in the Windows operating system, and the current performance of PCs can already be used as web servers for ordinary websites. The technology used in system development is also owned by itself, and it is also one of the widely used technologies today.
The development environment and configuration of the system can be installed by yourself. The system uses Java development tools and the relatively mature Mysql database to interact with the system's front-end and back-end data. The database is modified and maintained according to the technical language and combined with the needs, which can make the website The operation is more stable and secure, thereby completing the development of the website.
(1) Hardware feasibility analysis
The design of system management 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. The server to be uploaded after the platform is built is If there are certain requirements, the server must be chosen with relatively high security, and then opening the website 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, which ensures that data information can be backed up in a timely manner, and the entire system can Safe and effective operation.
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.
3.2 Economic feasibility
The market research conducted before the development of children's vaccine appointment management and other management systems related to it are free of charge. All investigations and research are done by the developers themselves, and all work is done by themselves. When encountering problems that are difficult to solve by themselves, most of them solve related problems with the help of their instructors and classmates. Therefore, the development of children's vaccine appointment management is completely economically feasible without any expenses.
Using relatively mature technology, the system is developed based on Java and uses Mysql database. Therefore, the system does not require high development manpower and financial resources and is economically feasible.
3.3 Operational feasibility:
Operability is mainly about the user experience after the design of children's vaccine appointment management is completed, and the administrator can manage relevant data information at any time through the system, and both administrator and user roles can be entered simply and clearly Go to your own system interface, and you can operate function modules simply and clearly through the interface navigation menu, which facilitates user information operation needs and administrators to manage data information. For the operation of the system, no professional is required to directly operate and manage the functional modules, so the operability of children's vaccine appointment management is completely possible. The operation of this system also uses the interface window to log in, so as long as the operator knows simple computer operations, it is completely fine.
3.4 System design rules
This children's vaccine appointment management is developed using Java technology and Mysql database, which fully ensures the stability and integrity of the system.
The design ideas and implementation of children's vaccine appointment management are as follows:
The operation is simple and convenient, and the system interface is safe and good: the simple and clear page layout makes it easy to query relevant information about children's vaccine appointment management.
2. Instant visibility: The processing of children's vaccine appointment management information will be immediately available for query at the corresponding location, thereby realizing the system function of "instant release and immediate effect".
3. Complete functions: can manage home page, site management (carousel chart, bulletin board) user management (administrator, system user) content management (information list, category list) more management (reservation orders, vaccine information, cancellation) Appointment, vaccine purchase, vaccine return) module modification and maintenance operations.

6 系统测试
6.1系统测试的目的
程序设计不能保证没有错误，这是一个开发过程，在错误或错误的过程中都是难以避免的。虽然这是不可避免的，但我们不能使这些错误始终存在于系统中，错误可能会造成无法估量的后果，如系统崩溃，安全信息泄露，系统无法正常启动等，为了避免这些问题我们需要测试程序，在测试过程中发现问题并纠正它们，从而使系统更长时间稳定成熟。
本章的作用是发现这些问题，并对其进行修改，虽然耗时费力，但对于长期使用而言是非常重要和必要系统的开发。
软件在设计后必须进行测试，调试过程中使用的方法是软件测试方法。在开发新软件时，系统测试是检查软件是否合格的关键步骤，以及是否符合设计目标的参考。测试主要是查看软件中数据的准确性，正确的操作与否，以及操作的结果，还有哪些方面需要改进。
儿童疫苗预约管理的实现，对于系统中功能模块的实现及操作都必须通过测试进行来评判系统是否可以准确的实现。在儿童疫苗预约管理正式上传使用之前必须做的一步就是系统测试，对于测试发现的错误及时修改处理，保证系统准确无误的供给用户使用。
6.2系统测试方法
在对儿童疫苗预约管理进行测试的时候在找到问题的情况下必须在第一时间找到解决问题的办法，不要存在侥幸的心理，这样才能让儿童疫苗预约管理开发的质量可以过关，并且开发的周期会大大缩短，还有就是在测试时，不要出现重复性的错误，遇到一个错误问题，要将整个儿童疫苗预约管理开发所牵扯的该问题都必须一一解决，提高儿童疫苗预约管理平台的安全性、稳定性。
白盒测试与黑盒测试是测试中比较常用的两种方法。
①结构测试俗称白盒测试：这种测试是在对程序的处理过程与结构都有详尽谅解的前提下，顺从程序内部的逻辑而完成的系统测试，以确定系统中所有的通路都能够遵照设计要求正常工作，不出现任何偏差。
②功能测试又成黑盒测试：主要是针对程序功能能够按照设计正常实现的一种检测，在程序接口处进行，检测程序手法数据是否正常，与外部信息的交换是否完整。
6.3测试过程
在软件的测试过程中，通常测试人员需要针对不同的功能模块设计多种测试用例。通过测试用例能够及时发现代码业务逻辑上是否与真实的业务逻辑相对应，及时发现代码上或逻辑上的缺陷，以此来来完善系统，提高软件产品的质量，使软件具有良好的用户体验。

6.4 测试结果
经过对一系列测试结果的有效分析，本平台开发系统符合用户的要求和需求。所有的基本功能相对齐全，操作起来简单方便，测试系统性能良好，作为大众化系统使用是比较值得推广宣传的。
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儿童疫苗预约管理的可行性，本文结论及研究成果如下：实现了java与Mysql相结合构建的儿童疫苗预约管理，网站可以响应式展示。通过本次儿童疫苗预约管理的研究与实现，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。
通过这次儿童疫苗预约管理的开发，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，儿童疫苗预约管理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。
致 谢
