## 介绍 ​ Hi,My Name is JackLin,I'm from class 1809, software engineering. This is my powerpoint, my team's topic is `Technology in the field of electronic commerce`. ​ All right, let's start with my speech. ## 电子商务领域技术简介 ​ In order to better understand the `Technology in the field of electronic commerce`, I first to introduce what is the electronic commerce. ​ (为了更好的理解电子商务领域技术,我首先介绍一下什么是电子商务) ----- ​ **Electronic Commerce is the use of computer technology, network technology and remote communication technology to achieve the whole business (business) process of electronic, digital and networked. The value of e-commerce is to let consumers buy and pay online through the network, which saves time and space between customers and enterprises, greatly improves transaction efficiency, especially for busy workers, and also saves precious time. In the 21st century when consumer information is diversified, it has become a habit for consumers to know the commodity information of local shopping malls through network channels such as Baidu Weishou, Taobao, New Eggs and so on, and then enjoy on-site shopping. E-commerce is the direct product of the explosive development of the Internet and a new development direction of the application of network technology.** ----- ​ The `Technology in the field of electronic commerce` can not leave the Internet, it has a close relationship with the Internet. ----- ​ **Internet itself has the characteristics of openness, globality, low cost and high efficiency. It has also become the intrinsic feature of e-commerce, and has greatly exceeded the value of e-commerce as a new form of trade. It will not only change the production, operation and management activities of enterprises themselves, but also affect the economic operation and structure of the whole society. The "electronic" technology platform based on the Internet provides a vast space for the development of traditional business activities. Its outstanding advantages are incomparable with traditional media means.** ## 目录 ​ OK, this is the contents of PPT. I will talk about e-commerce technology from the following eight chapters. ---- ## Chapter 01 Defination ​ The Chapter 01, is about the defination of `electronic commerce`. Here, I will give a detailed definition of e-commerce. ​ **E-commerce refers to business activities that use information network technology as the center and commodity exchange as the center; it can also be understood as the activities of conducting transaction activities and related services through electronic transactions on the Internet, intranets and value-added networks, and is traditional business activities. Electronic, network, and informatization of all links; business activities using the Internet as a medium all belong to the category of e-commerce.** ---- ### 1.1 Summary——小结 ​ Well, here, I will make a brief summary of the definition of `electornic-commerce`. ​ **With the rapid development of the Internet, the surging websites have turned to pragmatism one after another after they have fully exploited the concept. One of the distinctive features of pragmatism is that most websites are trying to do real e-commerce. The two most commonly used services in e-commerce are Web services and e-mail services.** ### 1.2 Constute—— 组成 ​ Electronic Commerce mainly consists of the following two parts. ​ First, **The so-called technology of electronic commerce is to use computer technology, network technology and remote communication technology to realize the electronic, digital and network in the whole business process.** ​ And the Second, **People are no longer face-to-face, looking at real goods, trading on paper documents (including cash). But through the network, we can browse a wide range of commodity information, perfect logistics distribution system and convenient and safe fund settlement system for trading (buying and selling).** ---- ## Chapter 02 History ​ The next Chapter, Chapter 02 History. It's about the history about `electronic-commerce` . ​ **Research on e-commerce in the world began in the late 1970s.** **The implementation of e-commerce can be divided into two steps,** **of which EDI commerce started in the mid-1980s and Internet commerce started in the early 1990s.**   **Generally speaking,** **e-commerce has experienced two stages of development:** **(1) EDI-based e-commerce (1960s to 1990s).** **(2) E-commerce based on the Internet (from the 1990s to the present)** ----- ### 2.1 EDI-based e-commerce 2.2 based on the Internet ​ The development of e-commerce has experienced the following two stages. ​ The first stage, is the EDI-based `electronic commerce`. ​ **EDI was produced in the United States in the late 1960s. When traders used computers to process various business documents, they found that 70% of the data manually input into one computer was derived from the output file of another computer. Due to excessive human factors, which affected the accuracy of data and the improvement of work efficiency, people began to try to automatically convert the data on the computers between trading partners, and EDI came into being.** ​ The second stage, is the based on the Internet. ​ **After the mid-1990s, the Internet became rapidly popularized, gradually moving from universities and scientific research institutions to enterprises and people’s families, and its functions have evolved from information sharing to Popular information dissemination.** ## Chapter 03 ---- Characteristic ​ `Electronic-commerce` has the following three characteristics. Wider Enviroment, Broader Market, Circulation and Price. ​ The frist characteristic, Wider Enviroment. ​ **People are not limited by time, space and traditional shopping. They can trade online anytime and anywhere. Through spanning time and space, we can reach more customers in a specific time, and provide us with a broader development environment.** ​ The Second Characteristic, Broader market. ​ **On the Internet, the world will become very small, a business can face the global consumers, and a consumer can shop in any business in the world. A merchant can challenge different regions and different types of buyer customer groups, and collect abundant buyer information on the Internet for data analysis.** ​ The last characteristic of `electronic-commerce`, Circulation and Price. ​ **E-commerce reduces the intermediate link of commodity circulation, saves a lot of expenses, and thus greatly reduces the cost of commodity circulation and transaction. Through e-commerce, enterprises can match buyers more quickly, realize real integration of production, supply and marketing, save resources and reduce unnecessary production waste.** ------ ## Chapter 04 ---Examples ​ Ok, this is the chapter 04, I will give some examples about `electronic commerce`. ​ Online shopping, Mobile phone order electronic newspaper, International tourism and travel service . Web workstations and work outlets, and Manufacturers of computer, network, data communication software and hardware. ​ First, the online shopping. ​ **With the rapid development of the Internet, people's lives and transactions have become simple, and a new dao-style shopping method has entered our lives. This is online shopping. Online shopping is to retrieve product information through the Internet. And send the demand through the electronic order, then fill in the information, the manufacturer sends the goods according to your information. Shopping sites such as Taobao, JD, and Amazon are all types of online shopping.** ​ Second, services. ​ **industries of various countries, such as hotel, restaurant, airport, station booking, rooms booking, information release and other services.** ## Chapter05 Technology involved ​ The next chapter is chapter 05, This chapter is about some of the technologies involved in `electronic-commerce`. ​ Here are six major technologies, which are network technique, Web browsing technology, Safety technology, Database Technology, Electronic Payment Technology, and the Classification. ---- ## Chapter06--- Technical requirements ​ This chapter is about technical requirements of `elecronic-commerce`. ​ The first technical requiremet is safety. ​ **To ensure the security of data transmission is to ensure that data information transmitted on Internet is not monitored and stolen by third parties. Generally, the protection of data information security is achieved by using data encryption technology.** ​ The second technical requriement is data integrity. ​ **To ensure the integrity of data is to ensure that the data information transmitted on Intemet is not tampered with. In e-commerce application environment, data integrity is guaranteed by using secure hash function (Hash function, also known as hash function) and digital signature technology.** ​ Then, the next technical requirement is identy authentication. ​ **In e-commerce activities, the two or more parties often need to exchange some sensitive information (such as credit card number, password, etc.). At this time, they need to confirm the real identity of the other party. If Payment-based e-commerce is involved, it is also necessary to confirm whether the other party's account is genuine and valid. Identity authentication in e-commerce usually uses public key encryption technology, digital signature technology, digital certificate technology and password technology.** ​ The last technical requirement is Non-repudiation. ​ **When transmitting data and information in electronic commerce, each party must carry its own unique information that cannot be duplicated by others, so as to prevent the sender from denying that the message has been sent or the receiver from denying that the information has been received, so as to ensure that the transaction is recorded when it occurs. Non-repudiation of transactions is achieved by digital signature technology and digital certificate technology.** ## Chapter 07 Advantage and Disadvantage ​ In this chapter,I will introduce the advantage and disadvantage of `elecronic-commerce`. ​ First of all, the advantage of `electronic-commerce`. ​ **electronic commerce digitizes and digitizes traditional business processes.On the one hand, electronic flow replaces physical logistics, which can greatly reduce manpower, material resources, and cost. On the other hand, it breaks through the limitations of time and space, making transaction activities possible. It is carried out at any time and any place, which greatly improves efficiency.** ​ 。。。。。。(还有5点,看PPT念就ok) ------ ​ However,there are some disadvantage in `electronic-commerce`. ​ The network itself has limitations: in this mode, only rely on the production of the website and the web designer to grasp the web page better model, to show consumers the goods. ​ 。。。。。。(还有5点,看PPT念就ok) ## Chapter 08 Futuer Development ​ 照着PPT念 ​ Ok, that's all for my powerpoint.
