【正文】 ded users with the following functions: membership registration、 shopping car management、 goods search、 information modify etc. It has also provided managers with goods management、 customer information management、 news management 、 ad management and so on. It has been designed with B/S mode of threetier structure, JSP technology in dynamic page design. Considering from the security and reusing code of the system, key codes has been secured by JavaBean technology. MySQL database has been used as the background database. The paper mainly introduced this, detailed introduced some thoughts and method of system analysis,system design and database ,in the chapter of system design,author listed the detailed algorithm of how to implement online system rely on Web server and client’s broswer,making use of the electronic instrument’s characteristics of highefficiency and lowcost,providing a trading flat for client,release bussiness information in the Inter,enable the user to look up, search,subscribe the client with fulltime,better,faster space of mercial activity.
