Vast quantities of data are generated through the health care process. While many studies to analyze the multiple database are being tried in the business area, a few studies have been done in medical area. We tried to study the seasonal variation of tests using two hospital data on mass screening. We received 79772 data from Seoul Joongang Hospital and 12330 data from Ajou University Hospital, and changed from text file to DBF. Inpromptu and Powerplay were used as the tools of data warehousing. The modeling and analysis was done effectively through the tools. The tests of seasonal variation were 6 items.
