摘　　要：针对电子病历系统中病人数据如何格式化处理、信息如何交换与共享等问题,展开了基于XML的电子病历数据存储研究。该研究以病人为根的树状结构化的数据结构为分析对象,并借助DTD(文档类型定义)标准定义该数据结构,克服了为适应病历中不同内容结构的变化,而改动程序的传统做法。该文选取DB2作为电子病历的数据管理平台,利用其兼具处理关系数据和XML数据的特点,实现了病历信息的结构化存储及交互,为分布异构系统之间临床信息集成奠定了基础。According to the problems as how to deal with patients data formatting, and how to transfer and share information in electronic medical record system, the data modeling method based on XML was raised by this paper. By means of data structure defined by DTD, this method analyzed the data structure rooted by the patient,which to overcome modifying code when someplace needed to change in electronic medical record system. DB2 was selected to be data management platform for the electronic medical record system. By adopting the characteristics of DB2 with relationship data and XML data processing, the medical records are structured stored in DB2, which also lays a foundation of clinical information integration in distributed and heterogeneous system.
