基于XML的医院信息系统数据集成方案研究

Scheme of Data Integration in Hospital Information System based on XML

针对现阶段医院各系统的数据源存在异构性但数据量大的问题,采用XML技术研究医院信息系统数据集成的方案,提出基于XML技术的医院信息系统数据集成的总体结构,具体探讨数据集成过程中的关键技术——公共数据模型、查询处理器和包装器。

Aimed to heterogeneous and vast data sources of hospital information system, a scheme using XML technology for data integration was studied. System architecture based on XML technology in hospital information system data integration was proposed. The key technology of data integration--Common Data Model, query processor and wrapper were illustrated particularly.
