INTRODUCTION Since 1978, the Computer Center of the Kanazawa Institute of Technology (KIT) has been engaged in the task of disseminating machine-readable astronomical data to the astronomical COI1UlIunity in Japan. The basis of the data service is a collection of data files (star catalogues) supplied by the Strasbourg Stellar Data Center (CDS), but locally produced data files are also being added. The current holdings at KIT is about 200 catalogs (about 300 data files if subfiles are counted). The main task so far has been to supply the user with duplicates (on magnetic tapes) of files, or with their printed versions.

Output data files user workspace Figure 1. Structure of the Astronomical Data Management System. on-line, only about half of them are currently resident on disks, for the reason of economy. Nevertheless, files on off-l~ne tapes can still be accessed in the same fashion, though, in this case, assistance from the computer operator is required. 3. FILE ProcESS~ LANGUAGES While almost any computer language can be used to process high-volume data files such as star catalogs, the amount of programming effort for a given task varies depending on what language one should choose.

Functions of ADMS are sumnarized in Figure 1. When the user wishes to work on a data file(s), he feeds in the file number through an on-line terminal. The system then retrieves the relevant storage information for the file from DO (Step 1) and incorporates the corresponding COD (Step 2). The user then types in EASYTRIEVE instructions, consulting the printed version of HOD and using the field names defined there (Step 3). Normally this amounts to only a few lines of input, since only procedural specifications are necessary.
