Research on the distributed electronic medical records storage model

The traditional electronic medical records storage pattern has became the bottleneck of its rapid development, this paper introduce the cloud storage mechanism for electronic medical records, HBase is a distributed column-oriented database built on top of Hadoop Distributed File System based on the common computer cluster. After researched on the distribution storage mechanism of Hadoop Distributed File System and the big unstructured and semi-structured data storage principle of HBase, the paper proposed a distributed storage model for electronic medical records based on HBase according to HL7, there are two NameNodes in this model, and a big storage table was designed to organize the data. This storage model is not limited with storage capacity, and provides fastly read and write performance and highly fault-tolerant.
