摘　　要：提出了公共数据交换系统 (PublicDataExchangeSystem ,PDES) ,旨在为同属于一个大型机构 ,物理上却分离的异构、异型、异地的应用提供透明的信息交换机制。着重阐述公共数据交换系统的应用背景、体系结构以及大型分布式环境下的应用举例 。Brings forward a new idea about integrating applications and information in distributed application environment with,Public Data Exchange System(PDES)aims at enabling the applications that belong to one large company or organization to exchange information transparently have different network connections, and work on different operating systems,with different hardware architectures and in different application environments.Discusses the problems to be solved by PDES. After that, the architecture of PDES is discussed and the design of PDES for a nationwide organization is given as an example.Finally gives the implementation strategy of PDES.
