1、 E-commerce system is a technical platform supporting the whole process of enterprise business activities From the perspective of enterprise internal management, enterprise activities include daily operation, management and decision-making. The e-commerce system relies on the enterprise internal management Network construction (Intranet), which supports the internal transactions of enterprises, not only serves the inventory, order, settlement and other transactions at the daily operation level of enterprises, but also supports the decision-making process. For example, as a part of e-commerce system, BI (Business Intelligence) proposed by IBM focuses more on the decision-making analysis level of enterprises, from the perspective of business activities between enterprises. The e-commerce system, through the Internet and the private network between enterprises (or the extranet), makes the enterprises form a close and dynamic business cooperation relationship. It supports e-Collaboration of enterprises, which enables enterprises to quickly adapt to the dynamic changes of market demand, thus leading enterprises and their partners to form a virtual alliance or common market in a certain sense. Therefore, whether it is internal production, sales and supply, or external market activities of the enterprise, it can rely on the platform of e-commerce system. This is the main feature of e-commerce system, which is different from MIS, DSS and other places to fully support all aspects of business activities of enterprises. E-commerce system is a technical platform for business process reengineering and value chain appreciation of enterprises. 
2、 As we all know, E-business pursues to complete the reengineering of enterprise business processes through "business integration" and give full play to enterprise information resources.
Improve the competitive advantage of enterprises. E-commerce system is the technical support platform to achieve this goal. Its analysis and construction cannot simply be based on the realization of electronic business processes. Although the analysis and design of the management information system also emphasize the need to start from the business process reengineering, relatively speaking, e-commerce systems emphasize how to achieve BPR through information technology means, and even in a sense, whether to realize the value-added of the enterprise value chain is a sign of the success of e-commerce systems.
3、 E-commerce system has high requirements on system and application security
However, almost all information systems have requirements on security. For example, it emphasizes the security level of the operating system, the security of data, and the backup of the operating equipment. But relatively speaking, e-commerce systems have higher requirements on security. The reason is that e-commerce systems generally deal with data related to business transactions. Therefore, business data involves sensitive data of enterprises. However, the requirements for security level are very high: Second, e-commerce systems rely on the network, especially the Internet. Generally, they operate in an open and public network environment, while the Japanese TCPiIP protocol itself has an end hole, so this open environment is relatively inclusive of closed systems, and there are some unsafe factors, Therefore, it is necessary to emphasize security measures to reduce risks: alas. Traditional business activities of enterprises are carried out under legal protection. When business activities are conducted under legal protection, the key system itself has high security standards. The transaction behavior of enterprises is transformed from tangible paper contracts into electronic contracts through contracts and contracts.
4、 Technical characteristics of e-commerce system
E-commerce system involves many aspects of modern computer technology and network technology. From a technical perspective, it has the following characteristics: (1) Sichuan distributed transaction processing system: (2) from the TCP/IP protocol; (3) using the client server computing mode. Interacting with clients through browsing a; (4) Web based and using standard protocols (such as HTML. WML. XML) to organize and express data. (5) The application system needs the support of an independent C ^ center, and needs to establish an interface with C ^: (6) It can be developed using a variety of tools, but the object-oriented Java system development is in the direction of taxi flow technology. Technology and reusable component technology are the requirements of e-commerce 4_ e-commerce system in system and application security.

Technology and reusable component technology are precisely because of this feature, which requires that the design and development of e-commerce systems should not be separated from the existing information resources of enterprises and consider how to help enterprises carry out business activities through the network in isolation
