Asp.net-based E-commerce System Design And Realization

With the international development of the information technology, especially the international popularization of Internet, global business activities has been influenced by the emerging electronic information technology. E-commerce begins to become a hot topic in business. In recent years, the application of the Internet has been promoting the development of electronic commerce. At present, the development environment of B2B e-commerce in our country is being perfected gradually, the country is gradually perfecting the laws, policies, and regulations, which provides safeguard and thrust for the regulations of the high-speed development of the Chinese B2B e-commerce.The e-commerce system can be divided into three subsystems, they are respectively: information management subsystem, background management subsystem, and business center subsystem. Among them, the business center subsystem is not only the core of the electronic commerce system, but also the key point during its process of development, which includes six major modules: systematic development of key, including users center, procurement center, marketing center, trading center, contract center and order center.The electronic commerce system looks on realizing network, integration, and individuation as the goal, and the Rational unified process (RUP) as a software development methods, unified modeling (UML) as analyzing and designing description language, uses SQL Server 2005 to build database on the basis of specific implementation technology, and realizes data security connection and access to achieve system of database with ADO.NET technology. It uses ASP.NET to build the user interface and program structure, with C# as development language, using Visual Studio language 2005 as a development tool, adopts B/S-based Three-Tier structure. And uses Ajax, Web Service technology etc, to complete the architecture of a system design and detailed design. And at last to fulfils a Cross-Platform and Cross-Area e-commerce system. And ensure the consistency, standardization and function integrity, operability, scalability, and maintainability of the system. This dissertation makes a deep analysis of the e-commerce system and conducts a systematic design, realization and testing. It firstly analyzes the present situation and development meaning of B2B e-commerce system, and then carries on the detailed analysis of requirement on the basis of the enterprise research and customer demand. Next it analyzes and determines the system structure and key technologies according to the electronic commerce system characteristics, and then carries on the system design and determines the frame structure, Database design, functional structure, etc. And at last realizes parts of the core function of the system and makes a test of it on the basis of detailed design.
