The R&D Of Online Shopping System Based On Windows DNA

Windows DNA is a scheme which is put forward by Microsoft and aims at developing strong,steady,extendible,distributed application on Windows platform.lt integrates all kinds of techniques such as NT,IE,nS,SQL Server and MTS etc.Its goal is establishing distributed application frame based on client/server architecture and Web technique .It provides the basic service for this application. Online Shopping System is the most representative and influential B to C electronic commerce system.Using Windows DNA as a design plan, Online Shopping System can be designed as three tiers network distributed application system including foreground processing module and background managing module.The foreground processing module is the end interface used by customers,from which the customers may choose goods,shop and pay.The background managing module,which includes the four subsystems such as users manage,goods manage,orders manage and report statistics, is the managing and maintaining environment for system developers and managers.After analyzing the information security of electronic commerce.this paper studies the architecture of Windows DNA .explains the design and relization of Online Shopping System,discusses the design method of Online Shopping System based on Windows DNA techniquesAt last ,this paper gives an instance of this model.
