The Research And Implement Of Campus Online Mall Based On The Asp.NET And B/S Three Structure

With rapid development of various technologies in electronic commerce and increasing perfection of relevant law, e-commerce is promoting the global economic with a strong power. As an emerging business mode, it is adopted by an increasing number of consumers and enjoyed more popularity. Therefore, as a significant applied field of e-commerce, campus e-commerce also receives the extensive concern day by day.

Meanwhile, the advantages and significance of developing campus e-commerce is analyzed by starting with the generally e-commerce system. Then detailed analysis about the campus e-commerce project of the Hunan Institute of Science and Technology (HIST) has been made, which includes project advantages, safety requirements, technical feasibility, functional requirements, the data flow and so on. Besides, modeling with case has been made to the system and the system structure as well as database system have been designed. Based on them, the online mall is designed which is the core applications of the campus e-commerce in HIST and includes the website system, the user login with permissions recognition module, the shopping and paying module, the information retrieval system and the credit evaluating model. The problems existed in the evaluation model of current e-commerce sites are analyzed in detail.
