The bookstore like the Xinhua Bookstore, the Jiangsu education bookstore, Jiangsu from tested the bookstore and so on all open the online bookstore. But in Jiangsu Province, online bookstores in the southern area are developed quicker than that in northern area. For instance in Huaian, the northern area of Jiangsu, only the largescale bookstore like Xinhua Bookstore has own online sell system. But the marketing channel of the middle and small scale bookstore like San Lian bookstore is still limited to the entity shop and the channel for online sales is waitting for develop. Infrastructure Purpose of the Online Book Sales System of Huai’an SanLian Bookshop is to set up a channel of information. Because the system runs on the Inter environment so both the suppliers and the operators must have a puter that connects directly to the Inter. Schedule of Project HYIT – GENETIC SINGAPORE COMPUTER SCHOOL GROUP 9 OBS For HYIT Page 9 BASIC KNOWLEDGE Method of Investigation The using of some methods for investigation is the first work before analyzing and designing programming. Although interviewing is the most monly used, the others are also valuable and effective techniques for requirement determination. We used the data collection method. We collected, obtained copies of the actual forms and operating documents that are currently used in the system as: information and images about products, and so on. HYIT – GENETIC SINGAPORE COMPUTER SCHOOL GROUP 9 OBS For HYIT Page 10 BASIC KNOWLEDGE CHAPTER 2 INTRODUCTION TO TECHNOLOGIES CHAPTER 2: INTRODUTION TO TECHNOLOGIES Programming Language Today, with the development of information technology, puter plays an important role in the technological science revolution. Computer brings to people interesting programs which can apply for education, entertainment and many other areas. And people can ask puter to execute something for them by creating programs. Certainly, the ability of us could not solve billions of plex digits and sort them in the particular orders, so to make HYIT – GENETIC SINGAPORE COMPUTER SCHOOL GROUP 9 OBS For HYIT Page 11 BASIC KNOWLEDGE programs more easily, more efficiently. In this project we are use some technologies include: Visual Studio 2020 Visual Studio is a plete set of development tools that are used to generate Web applications, XML Web services, desktop applications, and mobile applications. Visual Basic, Visual C ++, Visual c , and Visual J are all used for the same integrated development environment (IDE), you can share the tools and help to create mixedlanguage solutions. In addition, these languages leverage the functionality of the .NET Framework, which can be used to simplify the ASP Web applications and XML Web services technologies. In 2020, Microsoft released Visual Studio 2020. The word of .NET from a variety of language names in smears, but this version of Visual Studio is still targeting the .NET Framework (version ). It should also be able to develop crossplatform applications, such as the development of mobile operating system with Microsoft programs, etc. C C is a Microsoft released an objectoriented, run on the .NET Framework39。s success has had an enormous influence on the books sale domain. Compared to overseas, the domestic online bookstores are started late, and developed relative slowly.

When we design online book sales system, through our team members and teacher Hong to help ,After the feasibility of the system analysis, requirements analysis, outline design, detailed design and postmissioning. Finally pleted the system design and development. Here, We first want to thank our supervisor Hong, for her development of the whole process in the system give us valuable advice and guidance given to the patient. During system development, Hong at each stage in system design and development of innovative ideas and give their views, according to Hong design ideas, not only to perfect the functions of the system, but also to we are constantly learning system design exploration, gained more knowledge
