At the same time, it provides real and credible real-time and historic data for decision-making layer, scientific and exact performance index for enterprise to promote whole efficiency and competing advantages of compete price on the web.The paper analyses .NET Framework related technologies and web services firstly. We design an industry process real-time supervisory system using web service based on its system structure, and realize the conformity of web service and SQL SERVER 2000.Secondly, this paper analyzes the advantage in Real-time Supervisory under B/S architecture, supplying a solution on how to design a speedy, extensible, easy to using and full functional software with friendly UI in NET platform, and discussing the primary structure and principle. At last, it realizes user management, data-source management, publish produce processing graph, statistic table analyzing and alarming display and so on. The Key technologies have database connection pool, vml, and safe strategy using role management, system function authority control and database access authority.
