We devised a data format of a "Quick Look Information File (QLIF)" which carries various information extracted from observational data, and have developed a QLIF creation/browsing system, named "GYOJI", for the evaluation of data obtained with Subaru Telescope. A QLIF accomodates a two-dimensional image, typical profiles sampled from the image, one-dimensional traces of spectra, and various pixel statistics. All observational data of the telescope have a corresponding QLIF, and an observer or a user of the archive system is able to inspect the scientific information and the data quality from the QLIF without accessing the original data of complex structure and a huge size. Compared with the preview systems implemented in the astronomical archive systems in the world, GYOJI is superior in providing much information required for the data evaluation. This system has already become an indispensable part of the archive system of Subaru Telescope, and we think that this system has a great potential for the promotion of database astronomy.
