| 電子病歷中重疊時態(tài)數(shù)據(jù)的分析與消除 黃雄波[1] 陳章[2] 岳喜順[1] [1]華南理工大學(xué)自動化科學(xué)與工程學(xué)院,廣東廣州510641 [2]廣東商學(xué)院信息學(xué)院,廣東廣州510320 摘 要:隨著醫(yī)療數(shù)字化的發(fā)展，傳統(tǒng)的紙張書寫病歷正逐漸向電子病歷轉(zhuǎn)變。在醫(yī)院的現(xiàn)代化管理過程中，電子病歷作為醫(yī)療活動信息的主要載體而成為了醫(yī)院信息系統(tǒng)的核心，同時，它的設(shè)計也是醫(yī)院信息系統(tǒng)中最為關(guān)鍵的技術(shù)。文中用M.A.Roth等學(xué)者提出的嵌套關(guān)系數(shù)據(jù)庫模型在非時態(tài)DBMS上設(shè)計了電子病歷的時態(tài)數(shù)據(jù)庫，分析了該模型下產(chǎn)生重疊時態(tài)數(shù)據(jù)的原因，并在Delphi中詳細討論了重疊時態(tài)數(shù)據(jù)的消除原理及編程方法。 關(guān)鍵詞:嵌套關(guān)系數(shù)據(jù)庫模型 重疊時態(tài)數(shù)據(jù) 電子病歷 Delphi 分類號: TP311.11 文獻標識碼：A 文章編號：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 Automation Sci. and Eng., South China Univ. of Tech. ,Guangzhou 510641 ,China; 2. 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 |
