分布式信息系统中数据交换平台设计与实现

摘要

To adapt to exchange and share information between different region and different applications in the large distributed information system and improve the performance of the large distributed information system, a data exchange platform is designed and realized. Based on some solutions and the research of some technology such as JMS, A new data exchange platform is designed and realized. The data exchange platform is implemented by JMS information model and open source message middleware based on a SOA platform. The framework, transferring process, data encapsulation format of the data exchange platform is introduced. Some pieces of key technique such as the exchange interface and repeating query technology in this platform is described. The zero configuration and persistent, stable data exchange platform in large distributed information system is completed%为了提高分布式信息系统的性能,加快系统间的数据流通实现信息的共享和集成,需要为分布式信息系统建立数据交换平台.通过对数据交换平台现有的一些解决方案分析,在研究JMS (Java message service)等技术基础上,设计并实现了新的数据交换平台.利用JMS消息模式实现消息持久化,以开源消息中间件为交换中心,在SOA (service-oriented architecture)平台技术上完成了分布式信息系统的数据变换平台.详细介绍了平台设计架构、信息交换过程、数据封装格式,重点描述了发送接口、轮循器以及发送接收功能等关键技术的实现工作,完成了大型分布信息系统中消息持久化、零配置以及快速、稳定消息传送的数据交换平台.
