A Distributed Storage Model for EHR Based on HBase

HBase is a distributed column-oriented database built on top of Hadoop Distributed File System and Integrated into the Hadoop map-reduce platform. HBase provides distributed storage on the common computer cluster. Electronic healthcare record is the research focus of health care area, effective storage of Electronic healthcare record is the key for statistics, analysis and further use. After researched on the distribution storage mechanism of Hadoop Distributed File System and the big unstructured and semi-structured data storage principle of HBase, this paper proposed a distributed storage model for electronic healthcare record based on HBase. There are two Name Nodes in this model, and an electronic healthcare record storage table was designed to organize the data. At last, the future work about this model was discussed.
