基于DDS的异构系统数据交换技术研究

摘要

为满足日益增长的异构信息系统数据交换需求,研究了可扩展标记语言技术和数据分发系统发布/订阅模型,设计了一个实时、可靠的数据交换系统,降低了各交换节点之间的时空耦合性,有效地解决了异构系统之间的数据交换问题.%In order to meet the growing demand for heterogeneous information system data exchange , it uses XML ( Extensible Markup Language ) technology and DDS ( Data Distribution System ) publish/subscribe model to de-sign a real-time, reliable data exchange system .The system reduces the space -time coupling between switc-hing nodes effectively , solves the problem of heterogeneous system data exchange .
