For a discussion of .NET Framework version and its relationship to previous versions of the .NET Framework, see .NET Framework Architecture. Inter Information Services () Inter Information Services (IIS ) is Microsoft’s latest version of their web server. IIS has been included with Windows Server since Windows 2020 Server as a Windows Component and since Windows NT as an option. IIS is available with Windows Vista and Windows Server 2020, which is scheduled for release in Q1 2020. IIS has gone through a major overhaul and has been pletely redesigned from scratch. This has been done to make the most flexible and secure platform for web and application hosting. Based On B/S Architecture In the B / S system structure of the system, the user through the browser on the work to the distribution of many of the server request and then the server on the browser to process the request. The user information needed to return to the browser. B / S structure, simplify the work of the client and the client only need to configure a small number of clientside software. Server will assume more work and access to the database and application server implementation will be pleted. Browser making the request, while the other requests such as data processing, results are returned and dynamic web page generation, etc. all pleted by the Web Server. In fact , B / S architecture is to layer C / S structure of the transaction processing logic tasks from the client module to separate from the Web server is a separate ponent of its mandate to cover the floor, so that the client is alleviated, the load distribution to the Web server. This threetier architecture as shown : Threetier architecture Browse Web server Database HYIT – GENETIC SINGAPORE COMPUTER SCHOOL GROUP 9 OBS For HYIT Page 14 BASIC KNOWLEDGE This structure not only clients from the heavy burden and continue to improve the performance of its liberation of the requirements, but also the technical maintenance personnel from the heavy maintenance and upgrade work in earnest. As the client part of the transaction processing logic points to the function of the server to the client all of a sudden, slim, a lot, no longer responsible for dealing with plex puting and data access to key services, for display only part of the program is no longer so maintenance personnel maintenance of shuttling between each client, but to focus on functional update of the server program. This threetier structure in between the layers are independent of any level of change will not affect the functions of other layers. AJAX AJAX is Asynchronous JavaScript and XML (asynchronous JavaScript and XML), Ajax is a group of interrelated web development techniques used for creating interactive web applications. A primary characteristic is the increased responsiveness and interactivity of web pages achieved by exchanging small amounts of data with the server behind the scenes so that entire web pages do not have to be reloaded each time there is a need to fetch data from the server. This is intended to increase the web page39。s online bookstore develops well. 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 in
