§15. Study of the Data Base Management System for Atomic and Molecular Processes in Nuclear Fusion Science Ogasawara, R. (National Astronomical Observatory) Kanada, Y. (Computer Center, Univ. of Tokyo) Takasugi, K. (Nihon Univ.) Masai, K., Kato, T. There are several databases, which have been compiled at NIFS, for atomic and molec-ular processes concerning to the nuclear fu-sion science. Those data are obtained by experimental n1ethod and theoretical calcu-lations. Some of those data are retrieved on the main host computer at NIFS, Fujitsu l\1380, during about these ten years, and there have been provided a sophisticated retrieval systen1, RIC, which has been developed by Kato,T. et al.. RIC is a synthesized system based on the FAIRS, Facom Advanced Infor-Jnation Retrieval System, a product of Fu-jitsu Co. Ltd. to retrieve document database. RIC is the extended system to enable graphi-cal output by adopting User Exit function of FAIRS for those databases, AMDIS, CHART and SPUTY. On the other hand, there are so power-ful workstations, personal computers whose power is strong enough to n1anipulate so large data as has been contained in those databases ' and the ease of use for those small comput-ers make users tending to manipulate atomic-nlolecular data on their own computers. When constructing data base, the most troublesome is caused by the non-standard data format; there is no standard format of data neither for experiment nor for theoreti-cal ones. Hulse et al. suggested that a stan-dard format for data together with a tiny re-252 trieval system, called ALA U U lN, which can be available even on a personal computer with Fortran compiler. This system is superior in its universality or portability but is not di-rectly applicable for those database supported at NIFS. Now, we plan to open a new world of database system not only in its usage but also in its management. First, we will export the database system which have been created on a main frame computer onto a UNIX-base workstation, both for housekeeping and gen-eral usage of data. After the completion of this program, almost all workstation, oper-ated on UNIX will manage whole databases. Further, it will become easier to handle the result of retrieving data in user's private en vi-ronment, e.g., in FORTRAN program to cal-culate several physical quantities in plasma., such as cooling rate. We are thinking three years of program to achieve this aim. In the fiscal year of 1993, we made devel-opments in the following points. ( 1) Creat a data manipulating system on personal computer for the database AMDIS. It is now possible to reformat data and check the consistency of the input data on PC, then transfer them to the main fra.n1e computer. This is a good sample in linkage bet ween host computer and personal computer. (2) Made a prototype for the graphical in-terface on UNIX workstation to manipulate data. for the database CHART and SPUTY. The sheetspread input is faked on the dis-play of the workstation, and the data in-put/update becomes so easy. Based on these progress, we plan to en-hance the above system available on the net-work, then provide a retrieval systern corre-sponding to the FA IRS on the main frame computer. The graphical interface for general usage will also be created.
