1 Introduction

1.1 Research background and significance

Since its launch in the second half of 2016, WeChat mini programs have still received unanimous praise from the majority of WeChat users until today. Compared with traditional APPs, mini programs still have bright future prospects. For today's booming economy, especially for small and medium-sized Internet companies, WeChat mini programs will reduce R&D expenses and cycles and improve development efficiency. After several years of development, mini programs have continued to grow and mature, and have been making bold attempts in new fields.

Mini programs depend on WeChat, which has a vast user base. Based on the advantages and characteristics of mini programs, mini programs will eventually have an extremely large user base. In today's society, the economy is booming and the pace of life is accelerating. People spend less time reading and less time reading and communicating. But if people want to make progress and improve themselves, they have to study. Nowadays, most people like to read and are willing to squeeze in time to read. Whether it is novels or literary works, online reading seems to be a new trend. The developers took a fancy to this user demand and aimed to serve the majority of online bookworms, determined to develop an online bookstore mini program based on the WeChat mini program and give them a better user experience.

1.2 Research status at home and abroad

In China, because the Internet entered China relatively late, domestic bookstores are the only channel for buying and reading books in everyone's traditional concept. However, with the entry of the Internet into China and its rapid popularity in the country, everyone's concepts have also changed. , began to recognize the existence of online bookstores, and began to purchase and read books online, and this trend has not slowed down. To this day, people are more inclined to purchase books online. However, most of the ways to buy books online are by downloading mobile APPs and shopping on a specific mobile APP, such as Taobao, Dangdang and other software. But in recent years, a new way of shopping has emerged, which is shopping on WeChat, that is, buying books through the WeChat applet in WeChat. Although this method is not yet popular, it is better than shopping in a bookstore in the traditional sense. Shopping has certain advantages even over buying books through mobile apps. So now many mobile apps have begun to develop their own WeChat mini-programs, through which you can log in to your own software for shopping.

In foreign countries, the Internet developed relatively early, and people accepted shopping online earlier. Therefore, people also feel that buying books online is also very common. There are also many business companies abroad. Many of them buy books and enter to other pages to complete a perfect transition. However, because there are not many people using WeChat abroad, most bookstore systems based on WeChat mini programs are developed domestically. of.

1.3 Contents of system development

(1) First, determine the topic, determine the system to be built, and conduct a preliminary systematic confirmation of the background of the system and some of the problems currently faced.

(2) After the system is confirmed, the technology used in system development is confirmed based on the system development needs. The Springboot framework is used for the development of the online bookstore applet and the database is built and developed. The technology used is confirmed for technical analysis. Whether the technology used can complete the implementation of the system.

(3) Determine the technology used by the system, confirm online the user roles divided by the system, and determine the functional modules to be designed based on the user role division. The design of the online bookstore mini-program is mainly divided into administrator and user roles, and the platform Users are mainly targeted at users. After logging in, they can carry out book information and book purchases at any time according to their own needs. For platform management staff, they can process and operate online information according to their own content. Administrators can obtain the details of all users. Data information and be processed and solved as soon as possible according to needs.

(4) After the functional modules of the system are confirmed, the program and interface are designed. After the design is completed, tests are conducted to determine whether the program is perfect. For system testing, different users are required to edit and submit different content, and use different The testing method finds out the loopholes in the program and solves the loopholes in the program online. If there are no problems with the test system, the system can be uploaded for formal operation.

Chapter 6: Summary.

1.5 Introduction to the applet framework and directory structure

The entire applet framework system is divided into two parts: the logic layer and the view layer . The goal of the mini program development framework is to allow developers to develop services with native mini program experience in WeChat in the simplest and most efficient way possible. The mini program provides data transmission and event systems between the view layer and the logic layer, and provides its own view layer and logic layer framework, allowing developers to focus on data and logic. At the core of the framework is a reactive data binding system that makes it very simple to keep data in sync with views. If data is modified in the logic layer, corresponding updates will be made in the view layer. The framework provides a set of basic components, which come with WeChat-style styles and special logic. Developers can create powerful WeChat mini programs by combining basic components.

2 Analysis of the online bookstore mini program system

This chapter summarizes the feasibility analysis, functional analysis and use case analysis of the online bookstore applet.

2.1 Feasibility analysis

2.1.1 Technical feasibility analysis

After analyzing the real needs of the online bookstore applet, the roles required by the online bookstore applet were divided into Figures 2-1 and 2-2 below.

From the perspective of development tools, since the online bookstore applet is developed based on Java, it can be developed with all the development tools currently on the market. These powerful development tools can bring great convenience to me in designing the graduation design.

From the perspective of the technology of the online bookstore applet, it is not troublesome for me to develop an online bookstore applet. The development of the online bookstore applet can be simply divided into front-end module development, back-end module development and database development. Most of the technical difficulties have been used when I was in school, and there are many technical points on the Internet that I can learn from. The web backend management is developed using Java, and the database uses mysql. Therefore, it saves me a lot of redundant code in developing the online bookstore applet, which brings great convenience to my writing project.

2.1.2 Economic feasibility analysis

Judging from the development cost of the online bookstore applet, I completed the design and development of the online bookstore applet myself, and there were no other costs.

Judging from the maintenance cost of the online bookstore applet, the development of the online bookstore applet follows a complete set of coding standards, and the structural design of the online bookstore applet is very flexible and follows the principle of high cohesion and low coupling, so it is easy to maintain and Iterative development.

After the online bookstore mini program is launched, I will investigate based on real needs in the early stage of the launch and develop a set of appropriate usage fees for the use of the online bookstore mini program I developed. After the system is running stably, I will extend the promotion scope to other communities. They can register and use my online bookstore applet by themselves. They only need to pay a small deposit, and I will introduce advertising investment and self-operated business to them.

Based on the above analysis, the economic benefits brought by the online bookstore mini-program will bring great benefits. And with my promotion, the market for using the online bookstore applet I developed will become larger and larger. Therefore, from an economic perspective, it is feasible to develop an online bookstore mini program.

2.1.3 Operation feasibility analysis

The main service targets of the online bookstore applet are people who need to borrow books. Generally speaking, the use of the online bookstore applet is relatively simple. Generally, there are no difficulties in operation. The managers of the online bookstore applet need to use the online bookstore applet. You have a certain understanding of the bookstore applet, such as order list, book mall, book information and other operations. If you don't know how to do it, you can just get some simple training.

2.2 System function analysis

2.2.1 Functional analysis

I divided the online bookstore applet into two parts: the user management module and the administrator module.

Front-end user management module:

(1) User registration and login: The user registers as an official user and logs in to the online bookstore applet; the user adds, deletes, modifies and checks personal information, such as personal information and password changes.

(2) Users view news information: Users view information and can like and comment.

(3) My collection: Users can view their past collections of books and remove their favorites.

(4) Announcement information: Users can click the "Announcement Information" column to jump to the announcement information list and view the announcement information.

(5) Book mall: In the book mall, users can search and click on a book to view the details of the book and add it to the shopping cart or purchase it immediately.

(6) Orders: Users can view paid order list information.

(7) Shopping cart: Users can view the details of books added to the shopping cart.

Backend administrator management module:

(1) Carousel chart management: Administrators can add, delete, modify and check the system carousel chart.

(2) Member users: Administrators can control the registered user information on the front desk and manage the administrator's information at the same time.

(3) Announcement information management: Administrators can publish the latest announcement information of the system.

(4) Information classification management: Administrators can classify and manage information information.

(5) Book information: Administrators can maintain and manage book information.

(6) Book mall: The administrator performs addition and other maintenance management on the book mall.

(7) Order list: The administrator can manage the user's order information.

(8) Classification list: The steward can classify and manage books.

2.2.2 Non-functional analysis

The non-functional requirements of the online bookstore applet include the security, reliability, performance, scalability, etc. of the online bookstore applet. The details can be expressed in the following 3-1 table:

Table 3-1 Non-functional requirements table for online bookstore mini program

safety	Mainly refers to the installation of the online bookstore applet database, the use of the database and the setting of passwords must comply with standards.
reliability	Reliability means that the online bookstore applet can install and operate according to the user's instructions. After testing, the reliability is over 90%.
performance	Performance is a necessary condition for the online bookstore applet to occupy the market, so it is best to have good performance.
Scalability	For example, the database reserves multiple attributes, such as the use of interfaces, to ensure the non-functional requirements of the system.
Ease of use	Users only need to follow the content displayed on the page of the online bookstore applet, and that's it.
maintainability	The maintainability of the online bookstore applet development is very important. After testing, there is no problem with the maintainability.

2.3 System use case analysis

The complete UML use case diagrams of the online bookstore applet are Figure 2-1 and Figure 2-2 respectively. Include users as well as administrators on participants. User role use cases on the front desk include users who have registered as our members, user login, announcement information, book mall, news information, orders, shopping carts, basic information (personal information, password modification, collection), user role use cases are shown in the figure As shown in 2-1.

Figure 2-1 Use case diagram of online bookstore applet user role

The administrator on the web background management maintains all data information in the entire online bookstore applet. The administrator can perform login, carousel image management, announcement information management, administrator, member user, resource management (book information, information classification list ), mall management (book mall, category list, order list). An example of the administrator role is shown in Figure 2-2.

3.4 Summary of this chapter

This chapter mainly determines the functions to be realized by the entire online bookstore applet through feasibility analysis, functional requirements analysis, and system use case analysis. At the same time, it also provides standards for code implementation and testing of online bookstore mini-programs.

3 Overall design of online bookstore mini program

The main contents discussed in this chapter include the functional module design and database system design of the online bookstore applet.

3.1 System architecture design

This online bookstore applet is architecturally divided into three layers: presentation layer (UI), business logic layer (BLL) and data layer (DL).

Figure 3-1 Online bookstore applet system architecture design diagram

Presentation layer (UI): Also known as the UI layer, it mainly completes the UI interaction function of this online bookstore applet. A good UI can improve the user experience and enhance the user's comfort when using this online bookstore applet. The UI interface design must also adapt to different versions of the online bookstore applet and different size resolutions to achieve good compatibility. The UI interaction function requirements are reasonable, and users must obtain consistent interaction results when performing interactive operations. This requires the presentation layer to be well connected with the business logic layer.

Business Logic Layer (BLL): Mainly completes the data processing function of this online bookstore applet. The data transmitted by the user from the presentation layer is processed by the business logic layer and delivered to the data layer. The data read by the system from the data layer is processed by the business logic layer and delivered to the presentation layer.

Data layer (DL): Since the data of this online bookstore applet is placed in the mysql database on the server side, the parts that belong to the service layer can be directly integrated into the business logic layer. Therefore, there is only the database in the data layer, which mainly completes this task. Data storage and management functions of the online bookstore applet.

3.2 System module design

In the previous chapter, the functional requirements and non-functional requirements of the system were mainly analyzed, and the use cases in this online bookstore applet were analyzed based on the requirements. Then the next step is to start designing the architecture, main functions and database of this online bookstore applet. The online bookstore applet is derived based on the demand analysis in the previous chapter, and its overall design module diagram is shown in Figure 3-2.

Figure 3-2 Function module diagram of the online bookstore mini program

3.3 Database design

Database design generally includes three major processes: demand analysis, conceptual model design, and database table creation. The demand analysis has been explained in the previous chapter, and the conceptual model design has two parts: conceptual model and logical structure design.

3.3.1 Database conceptual structure design

The following is the ER entity relationship diagram of the main database tables in the entire online bookstore applet.

Figure 3-2 Total ER relationship diagram of the online bookstore mini program

3.3.2 Database logical structure design

From the total ER relationship diagram in the online bookstore applet in the previous section, it can be concluded that a total of many data tables need to be created. Here I mainly list several major database table structure designs.

5.2 系统测试结果

通过编写网上书城小程序的测试用例，已经检测完毕用户登录模块、用户注册模块、分类列表模块、书籍商城模块功能测试，通过这4大模块为网上书城小程序的后期推广运营提供了强力的技术支撑。

结论

至此，网上书城小程序已经结束，在开发前做了许多的准备，在本系统的设计和开发过程中阅览和学习了许多文献资料，从中我也收获了很多宝贵的方法和设计思路，对系统的开发也起到了很重要的作用，系统的开发技术选用的都是自己比较熟悉的，比如Web、Java技术、MYSQL，这些技术都是在以前的学习中学到了，其中许多的设计思路和方法都是在以前不断地学习中摸索出来的经验，其实对于我们来说工作量还是比较大的，但是正是由于之前的积累与准备，才能顺利的完成这个项目，由此看来，积累经验跟做好准备是十分重要的事情。

当然在该系统的设计与实现的过程中也离不开老师以及同学们的帮助，正是因为他们的指导与帮助，我才能够成功的在预期内完成了这个系统。同时在这个过程当中我也收获了很多东西，此系统也有需要改进的地方，但是由于专业知识的浅薄，并不能做到十分完美，希望以后有机会可以让其真正的投入到使用之中。

致谢

网上书城小程序的完成，标志着我即将结束在XXX大学的校园生活并跨入社会。在即将毕业的此刻，我想对所有帮助过我的师长、同学和亲人表达我发自内心的谢意。

感谢学校这个大家庭，在这里我们总能找到自己的归属。学校始终在向我们传达着温暖和关怀，接纳和包容我们的缺点。学校给我最大的感受便是要将自己的专业知识与实践相结合，而我也正在努力的成为学校所要求的应用型人才。

Thanks to all the teachers, the college has helped me move from ignorance to maturity step by step. Every teacher here has the greatest kindness and patience to educate us big children. Various activities organized by the college gave me the opportunity to exercise myself. It is these opportunities that made me a better myself and improved my abilities in all aspects.

Secondly, I would like to thank my thesis advisor. The reason why I am attracted to teachers is because of their friendship with students and their serious attitude towards work. From topic selection to topic development to thesis writing, the teacher has been giving careful guidance and will discuss solutions with us after pointing out existing problems.

Finally, I would like to express my gratitude to all the teachers who will participate in the review and defense of this paper.
