Reprinted from http://www.aspx.cn Web Services is the most popular enterprise-level technology today, more and more media is keen to talk about the emergence of innovation and various alliances in this field, and some manufacturers have announced them. The Web Services market, emerging companies have initiated the idea of implementing Web Services from the beginning. As the saying goes, I am not afraid. Web Services' hot is also from its business value and its commercial interests. Further, Web Services represents the major development of Internet technology, and companies have obtained all kinds of interests from Internet technology, while Web Services will make this benefit more. Gartner Group proposed in 2002: Web Services is a new way to think about how to obtain and provide business services, which brings huge benefits, including cost, shorten the system's installation time, and improve the agility and flexibility of your company. . From the perspective of IT technology, the direct factors affecting the speed of the enterprise are the flow of people, processes and information inside and outside the enterprise. People, information and processes are increasingly relying on IT means to integrate into a whole, and Web Services enhances integration along this direction, so that companies have developed to "high interconnection and automation". In other words, people, process and information integration requirements provide broad martial arts for Web Services. ● Web Services makes people, process, and information more easily, shorten business process cycles, improve response speed; at the same time, it can provide critical data for more applications and users to give companies agility And flexibility. ● Web Services simplifies the customer's self-service system, so that all functional departments within the enterprise understand customers through a "window", which makes customers contact the entire enterprise through a "window" to exposure to the company's new products and services. This helps enterprises to establish a long-lasting, loyal customer relationship. ● Web Services helps improve corporate efficiency, quality and speed of decision making. For now, only Web Services can integrate data in various systems, information. And let managers access this data in real time, while also allowing partners, channels and suppliers to access directly. Related information and services to facilitate their optimization of important value chain processes such as design, procurement, production, inventory management, sales. Web Services technology labeled mature as emerging technology, Web Services is still in development and improvement. The basic function of WebServices is to connect to each other between the computer system and the application system. Therefore, the Web Services is complicated on the technical itself. In popular, "Web Services" is a collection of technologies such as URI, UDDI, XML, WSDI, SOAP, HTTP, SSL, and more. These technologies play different roles, so people are divided into three categories according to their functions: discovery, description, delivery, so-called "3D" of Web Services. As the name suggests, the main function of "Discovery" technology is to discover Web services, such as URI and UDDI; "Description" technology implements Self-description of Web Services, such as XML and WSDI, etc .; "Delivery" technology supports construction The communication infrastructure of Web Services, including SOAP, HTTP, and SSL.
Playing a bit, if the Internet is metaphor into a street, the street is full of advertisements, when you walk on the street, you can only look at the advertisement and get some information. After the Web Services technology is applied, the streets are not only advertising on both sides, but also there will be a restaurant. That is, you can get information not only, but also you can get a service. In this case, UDDI will first help you "discover" a Chinese hotel; the menu of the hotel uses XML or WSDI "describes the situation of various dishes, that is," describes "the service of the hotel; Finally, SOAP can Help you communicate with the waiter and get the desired service, thereby completing the process of "delivery". (It should be noted that before using Web Services, it is the interactive relationship between people and machines. After using Web Services, it is the interaction between the computer and the computer.) From the perspective of development, the above technology can be divided into "core "," Core "and" expansion "technology. "Core" technical representatives have matured, stable technologies, as those listed earlier belong to this. They constitute the basis of implementing Web Services and get support from all Web Services platforms and is pushing the widespread use of Web Services. "Core standards that are forming" refers to the technical specifications that have been published by the manufacturer, including security, reliable communication and asynchronousity required for enterprise applications, and solve the problem of interoperability between different manufacturers. day. But in the same vendor environment, such as BEA WebLogic, these technologies are available and can be used to achieve security, reliable, asynchronous web services. Finally, "extended" technology refers to the technology required for specific applications. In fact, most enterprise web services does not need them, and their maturity requires a long time. From the Web Services, due to the maturity, stability of the "core" standard, Web Services is popular, especially in the integration of internal integration. At the end of March, the Wall Street Journal has issued Web Services reported in Virgin Mobile (US), reflecting the practical application of Web Services in business sectors. Virgin has the largest all-digital, all PCS wireless network, which has created a real-time communication center using BEA WebLogic Platform and Web Services, which is perfectly connected to its technical facilities, including cellular network, customer relationship management system And the background system provides customers with a wide range of content, real-time mobile services, fully reflecting its faster speed, innovation, reliability, and easy service characteristics. Not only is the telecommunications industry, but the Web Services is currently widely used in e-government, financial, retail, energy, transportation, electronic manufacturing, software, geographic information services, etc. It is believed that the use of Web Services will experience several phases such as early application, systematically deployment, and new business models. In the mid-2002 mid-term, it is the first phase, and the internal integration project is added, and the drive factor is cost effective and excavated to have an ability to invest in investment. Early applicants from financial services, high-tech manufacturing, communications, automotive and insurance, etc. From the second phase of 2002 to the beginning of 2004, the company will systematically, strategically develop and adopt Web Services to tertion existing processes. After entering the third phase, new business models driven by Web Services will appear and real dynamic business relationships.
