Application of Data Warehousing and Data Mining in HIS

Objective To discover the basic principle of hospital operation and predict the hospital developing trends through analysis of massive data involved in the hospital information system(HIS),with a view of providing better services to patients.Methods The Oracle Warehouse Builder was used as technical platform of date warehouse building in the process of modeling the HIS by using relational database and modeling the data warehouse by using the star model of the multi-dimensional database models.Data Miner,a data mining tool,is also applied to analyze information in the hospital related to inpatient structure and mobility,expenses structure,medical workload and economic benefits.Results Support was provided to management and decision making in hospital.Conclusion Wide applications of data warehousing and data mining are observed in HIS,resulting in remarkable economic and management benefits.
