【摘要】：隨著社會信息化的飛速發(fā)展，，國家衛(wèi)生部就推進醫(yī)療衛(wèi)生行業(yè)信息化建設作出專門的強調。本文則以省衛(wèi)生廳的“區(qū)域醫(yī)療監(jiān)管平臺”課題為研究基礎，針對醫(yī)療衛(wèi)生行業(yè)的信息孤島、信息協(xié)同共享及監(jiān)管困難等難題，提出構建醫(yī)療衛(wèi)生信息數據中心，并把所有醫(yī)療行業(yè)的數據同步到數據中心的設計思想來解決這些難題。在此過程中就需要解決醫(yī)療衛(wèi)生數據中心的構建、異構關系數據庫到數據中心的同步和數據中心效率問題就構成本文研究內容。 通過深入的研究分析醫(yī)療衛(wèi)生信息數據中心規(guī)模及相關需求問題。在對比和分析關系數據庫與新型的NoSQL數據庫的差異后提出運用NoSQL數據庫來構建，通過分析幾種NoSQL數據庫特點確定以HBase構建醫(yī)療衛(wèi)生信息數據中心。為確定數據模型，提出以關系數據庫的E-R建�；A提出HBase的C-O-R建模思想，然后綜合分析衛(wèi)生部頒布醫(yī)療衛(wèi)生元數據標準和部分醫(yī)療衛(wèi)生機構的實際情況，實現醫(yī)療衛(wèi)生信息的HBase數據中心構建。 為實現把各醫(yī)療機構的異構關系數據庫中的數據透明無差異的同步到數據中心，提出以下方案。首先，在數據格式上提出異構數據庫產生的異構數據進行標準化的XML和JSON通用數據格式封裝實現屏蔽異構數據庫的數據差異；其次是傳輸協(xié)議簡單及通用，采用SOA架構設計思想，提出運用Web Service方法實現數據同步傳輸；在異構數據庫的增量數據獲取方面揉合時間戳、觸發(fā)器及日志法為一體的方法；最后，提出通用前置機設計實現對所有異構數據庫的讀取，實現采用XML文件對異構數據庫的差異配置。 在構建好HBase中心并擁有數據后，由于HBase對于數據訪問只有Row Key的定位及全表掃描兩種，為了提高復雜查找效率而提出HBase的列索引構建。本文提出兩種索引設計方式：運用Row Key優(yōu)勢和構建索引表。本文索引表的構建是采用MySQL數據庫與HBase數據庫相結合的雙索引體系結構。 最后經過模擬測試分析，并同MySQL的相關測試性能進行對比，驗證出本文的設計方法可以較好的完成醫(yī)療衛(wèi)生信息中心的構建和異構數據庫到數據中心的同步，實現醫(yī)療衛(wèi)生數據共享、監(jiān)管及業(yè)務協(xié)同。
[Abstract]:With the rapid development of social informatization, the Ministry of Health has made a special emphasis on promoting the construction of medical and health industry informatization. On the basis of the research of "Regional Medical Supervision platform" of the provincial health department, aiming at the problems of information isolated island, information sharing and supervision difficulties in the medical and health industry, this paper puts forward the construction of the medical and health information data center. And all medical industry data synchronization to the data center design ideas to solve these problems. In this process, it is necessary to solve the construction of medical and health data center. The synchronization between heterogeneous relational database and data center and the efficiency of data center constitute the content of this paper. Through in-depth research and analysis of medical and health information data center size and related needs. After comparing and analyzing the difference between the relational database and the new NoSQL database, the author put forward to use the NoSQL database to construct the medical and health information data center by analyzing the characteristics of several NoSQL databases. In order to determine the data model, this paper puts forward the C-O-R modeling idea of HBase based on E-R modeling of relational database, and then synthetically analyzes the actual situation of medical and health metadata standard promulgated by the Ministry of Health and some medical and health institutions. Construction of HBase data center for medical and health information. In order to synchronize the data in heterogeneous relational database of medical institutions to the data center transparently, the following scheme is put forward. First of all, in the data format, the paper puts forward the standard XML and JSON universal data format encapsulation of heterogeneous data generated by heterogeneous database to mask the data difference of heterogeneous database, and secondly, the transmission protocol is simple and universal. Adopting the idea of SOA architecture design, this paper puts forward the method of synchronizing data transmission using Web Service method, combining time stamp, trigger and log method in the incremental data acquisition of heterogeneous database. Finally, In this paper, a universal front computer is designed to read all heterogeneous databases, and the differential configuration of heterogeneous databases is realized by using XML file. After constructing the HBase center and having the data, the column index construction of HBase is proposed in order to improve the efficiency of complex lookup because HBase has only Row Key positioning and full table scanning for data access. This paper presents two methods of index design: using the advantage of Row Key and constructing index table. In this paper, the construction of index table is based on the combination of MySQL database and HBase database. Finally, through the simulation test analysis, and compared with the related test performance of MySQL, it is verified that the design method of this paper can better complete the construction of medical and health information center and the synchronization of heterogeneous database to data center. Achieve medical and health data sharing, supervision and business collaboration.
