| 电子病历中重叠时态数据的分析与消除 黄雄波[1] 陈章[2] 岳喜顺[1] [1]华南理工大学自动化科学与工程学院,广东广州510641 [2]广东商学院信息学院,广东广州510320 摘 要:随着医疗数字化的发展，传统的纸张书写病历正逐渐向电子病历转变。在医院的现代化管理过程中，电子病历作为医疗活动信息的主要载体而成为了医院信息系统的核心，同时，它的设计也是医院信息系统中最为关键的技术。文中用M.A.Roth等学者提出的嵌套关系数据库模型在非时态DBMS上设计了电子病历的时态数据库，分析了该模型下产生重叠时态数据的原因，并在Delphi中详细讨论了重叠时态数据的消除原理及编程方法。 关键词:嵌套关系数据库模型 重叠时态数据 电子病历 Delphi 分类号: TP311.11 文献标识码：A 文章编号：1673-629X（2009）03-0235-04 Analysis and Elimination of Overlapping Temporal Data in Electronic Medical Record HUANG Xiong-bo, CHEN Zhang, YUE Xi-shun 1.

School of Information, Guangdong Univ. of Business Studies,Guangzhou 510320,China Abstract:With the development in medical treatment digitization, paper medical record changes to electronic medical record（EMR）. As the main carrier of the medical activity information,EMR is the core of the hospital information system in the process of modem manage- ment of the hospital,mad the design of EMR is the key technique of HIS. Using nested relational DB model introduced by M. A. Roth, constructs a kind of temporal database of electronic medical record which is based on none-temporary DBMS. But since information in electronic medical record changes as time passes by, the problem of overlapping temporal data may easily turn up. Analyzes the reason of the problem, discusses the main principle to solve it, and introduces the programming method in Delphi. Key words:nested relational DB model;overlapping temporal data; electronic medical retard;Delphi |
