Investigation And Implement Of A Distributed TP System Based On WWW

This text is about the investigation of a Distributed TP system based on WWW, which combines the XML (Extensible Markup Language) with the Middleware technology. Conventional LTP systems are mostly of host/terminal Client/Server model. The shortage of the model is the platitude of user interface and the inconvenience operation. But the Distributed TP system based on WWW will cover the shortage. And on the base, an implemented system is completed, which is BizWeb/OLTP.A TP system based on WWW, BizWeb/OLTP, is carried out by adding a middleware based of XML between client and TP servers. As to this system, the key to integrate the convetional TP servers with WWW is the middleware on WEB server. So this paper focuses on the design and realization of the middleware.Firstly, this text discusses the 3-tier Client/Server model and some basic models used in Enterprise Application Integration mode on WWW and gives some important problems of the design and implementation of Distributed TP system based on WWW. Then it discusses some important technologies, such as XML, JAVA Servlet, SOAP and so on. Finally, it gives the functions and their implementations of the system.
