摘要： 提出了信息空间3层结构模型,并根据此模型设计并实现了铁路信息集成系统体系结构。当信息源数据库模式变更时,铁路信息集成系统只需在线自动调整映射并且不需修改使用此系统的应用程序。与现有铁路综合统计信息系统相比,铁路信息集成系统具有动态变更适应性。

Abstract: The paper proposes a three-layer structure model for information space. Based on the model, the paper designs the architecture for the railway information integration system. When the database schema evolves, the system can make adaptation online without modifying the applications. Compared with the current railway information statistic system, the railway information integration system outperforms.
