摘　　要：当今企业的信息化发展不断加快,迫切需要研究出一种代价低、效率高、复用性高的分布式异构数据库透明访问系统。结合当前数据集成与访问方面的技术,本文提出一种使用中间件基本架构、虚拟数据库策略、XML作为异构数据库数据交换手段的分布式异构数据库透明访问系统构建策略,旨在开发一种简单易用、效率高、可移植可复用的异构数据库透明访问系统。将该系统应用于高速列车数字化仿真平台中,结果表明该方案是一个较优的解决方案。With the quickly development of enterprise informationized, it is urgently required to study a distributed heterogeneous database transparent access system with low price, high efficiency and high reusability. Conbing with the current data integration and access to technology, this paper proposes a way to establish the distributed heterogeneous database transparent access system by using middleware architecture, virtual database strategy and XML as a means of data interchange, aiming to develop a database transparent access system that is easy-to-use, high efficiency, and transplanted reusable. The system has been used in the digital simulation platform of high-speed trains, and the experimental results show that the scheme is an optimal solution.
