Hyper Suprime-Cam (HSC) is the optical and near-infrared wide-field camera equipped on the Subaru Telescope. Its huge field of view (1.5 degree diameter) with 104 CCDs and the large mirror (8.2m) of the telescope will make us to study the Universe more efficiently. The analysis pipeline for HSC data produces processed images, and object catalogs of each CCD and stacked images. For survey in next 5 years, the number of rows in the object catalog table will reach to at least 5 x 10 9 . We show the outline of the database systems of HSC data to store those huge data.
