Abstract (in Japanese) (See Japanese page) 
(in English) Currently, a large amount of data is published on the cloud as big data. However, since it is not fit for the individual business systems, a huge cost is often necessary to prepare the business system data. On the other hand, due to security restrictions, it is difficult to directly reflect the business system data into big data. In this study, we create a standard database from big data to utilize in individual business systems efficiently; by converting the business system data to ensure security, we make it can be reflected into big data. Based on these, we propose a circulatory data model between cloud and business systems, in which the reflected data is utilized to create the standard database. We apply this model to the automatic English question creation and show that the accuracy of its difficulty can be improved with respect to the user's purpose and level.
