Design And Implementation Of Electronic Commerce System Based On ASP.NET

Electronic commerce is usually refers to a wide range of business around the world trade activities, in the Internet open network environment, based on browser/server applications, buyers and sellers not met for various business activities, realize consumer online shopping, online transactions between merchants and online electronic payment and various business activities, trading activities, financial activities and related comprehensive service activities of a new type of commercial operation mode. E-commerce system is the guarantee on the basis of the electronic commerce online trading system. This thesis developed system USES ASP.NET voice to development, database using SQL SERVER2008, architecture is simple, relatively website interface style is concise and clear, to provide customers with a better user experience, convenience of customers shopping at the same time also brought great convenience to system administrator. Through reasonable database structure design, web site scalability brought great improvement.The main function of this thesis introduces the shopping system is described, and through ASP.NET program and SQL database connection to process online registered users, through the realization of the online shopping website of conventional basic functions, will be able to start operations in the network. This system adopts B/S mode, the development uses ASP.NET, the backstage database adopts SQL Server and implementation of network electronic shopping system combined with the development of Web technology. The electronic commerce system is realized based on the ADO.NET technology, webpage implementation using ASP.NET technology, through the SQL language to realize with the operation of the database and the connection, mainly introduces the realization of the system function and the realization method, and the system technical difficult points were described in detail, such as the development of the Shopping Cart module is important in e-commerce website. The design of the database in this system is also very important, need according to the specific environment of electronic commerce website, construct the most appropriate and most excellent database model, but also can create database and the database table structure based on the model above, can more easily manage data, to meet the needs of the website each function module. If the database design is not appropriate, the biggest problem is the system, will lead directly to the design and implementation of electronic commerce website is unable to meet the expected demand.Methods the thesis strictly follow the software engineering and the thought of writing, from the e-commerce system demand analysis stage, to the overall design, system design, system realization main function modules in each stage of scheme, system function test and performance test of the whole life cycle of the electronic commerce system. In the demand analysis using the use case diagram model, are analyzed in detail the system design stage; in the overall design and function modules of the system, the database design to complete the design of the foundation of the whole system, in the implementation phase the function description, the program flow chart and code combined method are elaborated; at last system test module, are the function test and performance test of each function module, and finally through the test, verify the availability of the system, and to meet all the needs of system.
