According to the trend that the health and medical treatment data are gradually open to the public in the world, the integrated medical information system is required for the patients. By implementation of the medical expert system, representatives of the analytical results are average treatment expenses per medical center per disease, medical institutions frequently treating patients per disease, diseases susceptibility in the age group, number of patients per disease by region, and number of the medical clinics per department and district. The expert system makes the big data helpful for the medical centers, patients, governments, the medicine importers, pharmacists and insurance agencies etc. Overall, the expert system deals with not only the fundamental analysis of the diseases per age or per gender but also the practically beneficial information for all the interested parties with analysis of the public medical treatment big data. Furthermore, the expert system can easily be extended with increasing public medical big data open. Keywords: Big data, Expert system, Medical expense, Insurance agency, Medical center 1. INTRODUCTION to research articles in medical journals. [10, 12, 13, 14] The biomedical data have explosively produced Big data threw one of the major challenges in the hospital as well as on the mobile internet. The of information technology and statistics and has heterogeneous biomedical data are created from brought a great revolution from the algorithmic various types of data sources, which include the viewpoint and statistical framework.

Recently some statistical methods These health big data play an important role in the have been adapted to process big data, like linear data processing and analysis useful for the patients. regression models, bootstrapping schemes and [16, 17, 18, 19] In addition, the health big data also clustering schemes.

According to the available in the websites of Public Big Data Center trend that the health and medical treatment data are of Seoul City [26], Institute of Health Insurance gradually open to the public in the world, the Policy [27], National Cancer Information Center, integrated medical information system is required [28], Korea Breast Cancer Cyber Center [31], and for the patients.

Thus, with integration of public medical 3. THE SYSTEM MODEL AND ANALYSES big data it is necessary to implement the expert system for health and medical treatment. People 3.1 Entity-Relationship Diagram of the System would use the expert system to rationally select the The research system embraces an entity- medical centers, check the medical expenses and relationship model. In the entity-relationship model, decide better treatment method, etc. The expert an entity represents one theme or topic restricted to system creates various information through public things that can be conveyed by a single table and a medical big data and makes the big data helpful for relation consists of rows and columns that have the medical centers, patients, governments, the specific characteristics. In this system, the main medicine importers, pharmacists and insurance characteristics of the relation are that cells of the agencies.
