The Design and Implement of the System of Trade and Management of Products based on Online Supermarket
Abstract
As the close link of Internet with our lives, the online trading has been accepted by people gradually. So the online integrating system of trade and management becomes very important and useful. Therefore, this project designs the system of trade and management of products based on online supermarket. At the beginning, the paper introduces the origin, development and the current situation of the system of trade and management of products briefly. Then it describes some key technologies simply being used by the system. Finally, the system has been analyzed from several aspects, such as the analysis of requirement, designs of the whole system, database design and the implementation of system by using the methods of software engineering. Meanwhile, this project implements the functions which the system requires, including the catalogs, user registration, user login, shopping cart, order inquiry, maintenance and management of system and so on. The system builds this online shopping system based on
HTML,
JSP and SQL Server database. In the process of designing system, the thinking of modularization of pages and three-layer structure is adopted in the project. The operation of database is made by using
JavaBean. Servlets are used to achieve some parts of the system, such as the trade management and system maintenance. But lots of improvements should be made for this system, especially the security issue which is not solved properly.
