摘要
本文介绍了在建设出入境人员健康状况实时监测网络采用的基于Web Services的全相联异构数据集成方案,该方案利用Web Services的跨平台等特点,综合了数据仓库和虚拟数据库在异构数据集成中的优点,通过设计领域字典表及字段、量纲等映射表,有效地解决了异构数据集成中的环境异构和数据异构等问题,并从异构数据转化、全局查询等方面阐述了该方案的实现过程。实践表明,该方案对了分布式异构数据的共享问题解决具有可行性和高效性。
The article introduces a new scheme to integrate heterogeneous data based on Web Services which is proposed when building a real-time network for monitoring international traveler’s physical condition. This scheme using cross-platform characteristics of Web Services and the advantages of data warehouse and virtual database on data integration, through the design field dictionary tables, columns mapping table and dimensional mapping table etc, effectively solves the problems of environment heterogeneity and data heterogeneity, and discusses the feasibility of the solution from the aspect of heterogeneous data transformation and global query. Practice shows that the scheme of the distributed, heterogeneous data sharing problem solving with feasibility and efficiency.
