Web database application of three layered C/S mode

YIN Xü (Department of Computer Science & Automation, Beijing Institute of Machinery, Beijing 100085,China)  
In the traditional C/S mode,the data server would consume a part of the system resources to handle the connection with the client.The running of the system is inefficient.In the three layered C/S mode ,Business Service is added between User Service and Data Service ,mainly used to connect the data server with the client.The User Service is realized by Active X technology combined with HTML.In the Business Service ,ASP service program running in server access database by using ADO.The Data Service is realized by database administration system.So,the load of the data server is largely reduced, its responding speed is improved, and the running of the whole system is efficient.
