Medical data exchange and sharing system and method based on big data technology

The invention belongs to the technical field of big data and data exchange and sharing, and discloses a medical data exchange and sharing system and method based on a big data technology. The medicaldata exchange and sharing method based on the big data technology comprises the following steps: carrying out data analysis, statistics and cleaning operations based on a spark sql calculation engine;configuring parameters in a mapred-site.xml file, setting a MapReduce execution engine, configuring a spark-defaults.conf file and hive parameters, and establishing a basic-level hadoop environment;writing a method for dynamic analysis of configuration files; and performing integrated scheduling on kettle based on mule, and performing transmission and sub-packaging of the parameters to the configuration files. According to the method, batch automatic processing of data can be realized, and a data exchange and sharing rate is high; a compression technology is adopted in the acquisition process, so the pressure of a net
