Research On XML And Its Distributed Application

With the rapid development of the computer software and hardware, the programmers begin to apply themselves to the distributed application program, which can integrate the applications everywhere throughout the internet, rather than integrate the local services. XML, as the format of data expression and exchange on the internet scale, has been taking place of the current component technology and become the core technology of the distributed computing.In this paper, firstly, we did an introduction of the XML document structure,parsing model and display course, especially, researched the Web Services technologies in distributed environment. Secondly, aimed at the actuality and problems in data format,transformation and exchange of the current distributed application systems" architecture, and combined with the advantage of XML in distributed environment, we proposed a framework of distributed application. Its basic thought is that XML is the format of data store and exchange among layers in the system, so we can deal with the dates in a formal format; meanwhile, SOAP(Simple Object Access Protocol) is the communication protocol between servers in application layer, which is very convenient to remote transfer between different platforms. At last, we designed an application prototype based on this framework, and gave the implementary flows of some functions in client side and server side.
