Design And Implementation Of E-Shopping System Based On .Net

As Internet technology develops, people's daily life has been inseparable from the network. Future society, people's life and work will be increasingly dependent on digital technology, more and more digital, network, electronic, virtualization. E-commerce growing in tandem with the development of networks and close to people's lives. Internet, the application development process and the current status and development trend, we can fully believe that network technology will greatly change the way we live and work, and even society as a change can occur.E-shopping is based on information technology-based e-commerce activity, which through the Internet so that the parties are dealing in goods trade, because both sides from time and space limitations, thus not only greatly expanded its network of consumers and the commodity trading business opportunities, but also greatly reduce the cost of commodities trading.This system is subject to Shanghai Jia Mao's principal business for the commercial development of a set of characteristics of its system of online shopping, so that not every customer will be able to go out at home through the Internet to easily shop. The system used in the design of B/S three-tier structure, the use of ASP.NET technology for dynamic page design, the background based on the SQL Server database, is part of small and medium e-commerce system.This paper describes an E-shopping system status and development background, and then discusses the system design objectives, system requirements and design plan, a more detailed discussion of the system's detailed design and implementation. The system in the user information management security technology and online payment technology had its major tasks. For the user information management, security design, the system handled hashing function to hash design. At the same time, with non-symmetric encryption to ensure the privacy of their information. In the online payment function module design, the system design focuses on the preparation of IPN and PDT ports, and use. Php file to ensure payment of the state is unique.Finally, the paper made the system detect the problem and need to improve.
