Research on key technology of data mining based on hospital information system

At present, the processing of medical information is mostly based on the level of the operation of database technology, it is the specific application service. Hospital information system is a branch of medical informatics, which has accumulated a lot of management information and clinical information resources in hospital information system. How to excavate the deep level, implicit and valuable knowledge in the large amount of data resources is a difficult problem that we face. Data mining has the ability to solve this problem. Using data mining technology to carry out scientific research, improve the level of medical technology and hospital management is very necessary.
