摘要: XML is a more desirable format for modeling and storing clinical data in EMR (Electronic medical record) applications its extendibility; however, existing systems either are built on top of RDBMS or file lack support complex large scale healthcare applications, such as treatment effectiveness analysis procedure optimization. SAP Technology Lab, China developing clouds-enabled information appliance, Xbase, Hadoop, which the first XML-based appliance designed specifically applications. presents different set challenges query processing, indexing, parallelism, distributed computing using Hadoop's APIs well HDFS storage infrastructure MapReduce framework. In this paper, we describe system architecture internal designs Xbase how indexing mapped to Hadoop. We also discuss why select Hadoop over other candidates, Hbase, Google's Bigtable, Hive.
