Health insurance outpatient clinic big data extraction system and method based on hadoop platform

The invention discloses a health insurance outpatient clinic big data extraction system and method based on a hadoop platform. The system comprises a data acquisition module, a data storage module, a data cleaning module, a data analyzing and processing module, an Hbase distributed database and a data display module. The data acquisition module is connected with the data storage module, the data storage module is connected with the data analyzing and processing module through the data cleaning module, and a data query and analysis module is respectively connected with the Hbase distributed database and the data display module. The system and method have the advantages that a Hadoop cluster can be formed by thousands of cheap servers, a distributed file system cluster is constructed on large-scale cheap machines, data extraction and analysis cost is reduced to a large extent, and parallel processing can be carried out on outpatient clinic big data. Meanwhile, reliability and security of the data are well guaranteed by means of a transcript storage strategy of an HDFS.
