The Design Of The Enterprise After-Sales Server System Based On Web And Research Of The Encrypt Technology

In the process of informationalization, it's necessary for the informationalization of enterprise to establish an enterprise information system. An excellent information system can make enterprise more competitive and expedite the informationalization of enterprise. Now enterprises have been in more demand for the managing information by internet since the rapid development of internet and the improvement of economy globalization. Most of management information systems are upgrading from desktop application to net application. The structure of system is upgrading from C/S to B/S. The design based on Web is becoming the common standard of Management Information System Utilizing more Scientific and advanced technology to develop the new generation of management information system that satisfies the demand of enterprises now has been an emergent question.This thesis takes enterprise information system as a study object and makes a deep and systematic study of some key technologies into enterprise information system based on Web.Based on the analysis and summarization on lots of involved references,the paper expatiates the developments of the enterprise information system of our country and foreign country and development direction in future; explains the basic developing technology of Web, then brings forward to design the enterprise information system based on Web with .NET technology which is the most new technology,Based on analysis the DPAD's real business procedure and sofyware function demand, this paper provides the overall designing scheme of the system,and explains the design principle and aim of the system, network frame design, database design and framework design in detail.And puts forward safety design of this system.For solving data transfer safely, the paper bring forward mixed encrypt arithmetic based on DES&RSA, after introducing and analysing DES and RSA encrypt arithmetic;And the paper recommends the realization means and process design of this mixed encrypt arithmetic in detail.
