Three modes of inter enterprise e-commerce implementation

according to the different technologies adopted, there are three types of e-commerce modes implemented by enterprises at present: the first is the closed e-commerce mode based on value-added network and intranet. Under this mode, enterprises selectively receive information and control the users connected with enterprises. The activities of e-commerce among enterprises mainly support the information exchange and document transmission in the pre transaction and in the transaction stages. As for the post transaction stage, it must rely on traditional methods; The second is the inter enterprise e-commerce model based on the extranet of EDI. In this mode, the Internet technology is used to allow the units with close business relationship with the enterprise to realize the interconnection with the enterprise through the Internet, and prohibit the non associated units or individuals from connecting through the firewall to ensure the security of the network. The network can realize the transaction between enterprises; The third is the inter enterprise e-commerce model based on the Web Internet. This is the most commonly used mode at present, because the web-based inter enterprise e-commerce mode adopts standardized networks, standardized e-commerce protocols, and standardized general network commerce software to make the development and maintenance of e-commerce more standardized

closed e-commerce mode based on ERP

closed e-commerce mode is mainly based on value-added network and intranet. With the further development of the market competition pattern and the further acceleration of changes in market demand, In the 1980s, MRP II (Manufacturing Resources Planning) was mainly oriented to the comprehensive planning of internal resources of enterprises. Therefore, the result was that the product was a management idea that would continuously enhance customer satisfaction. The draft also stipulated that it wanted to gradually develop into the idea of how to effectively utilize and manage resources facing the whole society in the 1990s, ERP (Enterprise Resources Planning) came into being under this background. In the ERP system design, considering that it is impossible to effectively participate in the market competition only by relying on the resources of its own enterprise, it is also necessary to integrate the relevant parties in the business process, such as suppliers, manufacturing plants, distribution networks and customers, into a close supply chain, so as to effectively promote the smooth development of the production, supply and marketing activities of the enterprise, so that the enterprise can quickly and efficiently integrate the market resources of the whole society to meet the production and operation needs of the enterprise, Further improve the efficiency of enterprise management and gain competitive advantage in the market

EDI based e-commerce model

extranet applies the group technology of the Internet to the inter enterprise interconnection. It overcomes the shortcomings of the specificity and complexity of the special value-added network in the past, and uses standardized protocols and general software to realize the interconnection between enterprises. At the same time, it also blocks the information exchange between the extranet and other non business transactions through the firewall. Generally, in outreach, internal access to external mutual inspection electromagnetic clutch information is allowed, but illegal and anonymous visitors are not allowed to enter the network. Therefore, this mode is a semi closed inter enterprise e-commerce mode. Because the external connection of enterprises is close, the transmission of internal information is relatively safe. At the same time, because the enterprises of Lianhe are business cooperation units and partners, they realize the purpose of information sharing and common development through Lianhe. For example, Wal Mart in the United States connects its internal retail management network with its suppliers, allowing suppliers to timely understand Wal Mart's inventory and supply goods in a timely manner

edi (electronic data exchange) is an earlier and more common form of e-commerce among enterprises. It has developed from a special closed type to an open standard protocol. The transmission of EDI has also shifted from a special value-added network to an open interconnected network. In order to standardize and unify the format, the international Internet standard (rfc1767) defines the mine format as the transmission EDI message format. At present, the format of EDI message mainly follows the EDI standard format protocol un/edifact (United nations/electronic data interchange for administration, communication and transportation) formulated by the United Nations. EDI technology is relatively mature, the use cost is also very low, and the system installation and use are relatively simple. Therefore, EDI is the most widely used. It can not only carry out e-commerce transactions between enterprises, but also carry out data transmission with government agencies, such as customs declaration, government procurement and bidding. The disadvantage is that the data transmitted through EDI is limited, and it is not competent to conduct a large number of information inquiries before the transaction, provide post transaction settlement, and provide after-sales service. Therefore, EDI is generally used for the transmission of business letters during the transaction process, and the amount of data is not large

web based Internet e-commerce mode

this mode is through the construction of WWW stations, and Internet visitors can access enterprise sites through standardized browsers that support hypertext multimedia within the specified permissions of the sites. Access is interactive. On the one hand, you can obtain the required information from the station, and on the other hand, you can directly send information (such as orders and requirements) to the station. Because this mode has a standard software support platform, it has very low requirements for users, but puts forward high requirements for enterprises. The stations built by enterprises must have rich product information and provide relevant support services. Therefore, it needs to invest a lot of money to build a fully functional enterprise station supporting e-commerce. At present, the e-commerce models among enterprises based on Web include online store, professional service, hybrid and intermediary

(1) online store type. This method is often used by some large enterprises, because it has a large investment, but the cost savings and sales revenue expansion of the enterprise are also very considerable. If Dell makes its product catalog, types, specifications and relevant information of too high and too low voltage public on its website, customers can query and order according to their needs. There are two types of enterprises that conduct inter enterprise e-commerce. One is large enterprises. They generally query information, order information and technical support on the site, but do not order through e-orders; At present, small and medium-sized enterprises and consumers are still the most direct users of online ordering, which may be related to the different procurement procedures of different types of enterprises. Generally, the procurement of large enterprises requires collective discussion and decision-making, while small and medium-sized enterprises directly entrust individuals to complete the procurement
