Research on the EMR Storage Model

摘要：

Effective storage of EMR data is the foundation of the rapid development of EMR. This paper analyses and compares the three traditional storage pattern of EMR data firstly, and then proposes a combination storage plan using ralational databse and native XML database with fine-grained structure granularity of EMR data and according to the HL7 CDA, which is the international de facto standard of EMR. We refined and evaluated this solution by experiments, and it is proved that this storage plan not only could reduce the EMR data storage space and the query time complexity effectively, but also could facilitate the clinicians and researcher to use EMR data for statistical medical information, clinical diagnosis and other areas in the later period.
