基于Web Service进行信息共享和集成的关键技术

由于Web Service是基于标准协议和规范(包括HTTP、SOAP、XML、WSDL、UDDI等),并且平台独立和语言独立的,因此Web Service已成为基于Internet网进行信息交换、信息共享、信息集成和互操作的主流技术,在电子商务和电子政务中被广泛应用.详细介绍了基于Web Service进行信息共享和集成的关键技术--Web Service异步调用技术和动态调用技术.通过Web Service异步调用技术,实现了Web Service的分布式并行执行,提高了计算的效率.通过Web Service动态调用技术,使整个软件系统具有可扩充性,并且易于维护,能满足Internet环境动态性的要求.

Key technologies of information share and integration based on web service

Web services standards including HTTP,SOAP,XML,WSDL and UDDI,provide a high level of interoperability across platforms,programming languages and applications,enabling customers to solve information share and information integration problems easily.Therefore,web service has become a kind of main technology for information exchange,information share,information integration and interoperability in internet.It is generally used by E-business and E-government applications.The key technologies of information is shared and integration based on web service in detail: Asynchronous invocation of web service,dynamic invocation of web service.By using asynchronous invocation of web service,parallel executing of many web services implement distributed is,which reside in different computers in different positions.By using dynamic invocation of web service,it can make software system be expanded and be maintained easily.It can also make software system meet the requirement of dynamic of internet environment.
