Besides the more academic question, whether a B-tree plus SQL interface is a relational DB, the more interesting point for me is the fact, that this SQL interface is incomplete. It e.g. does not tell me, on which volume a specific backup copy of a file is lying. (It tells me all the volumes that contain a backup copy of that file; but which volume contains the active copy?)
I assume, that the SHOW command would give me that information (I did not try it), so the SHOW command is native interface to that DB. -- Reinhard Mersch Westfaelische Wilhelms-Universitaet Zentrum fuer Informationsverarbeitung - ehemals Universitaetsrechenzentrum Roentgenstrasse 9-13, D-48149 Muenster, Germany Tel: +49(251)83-31583 E-Mail: [EMAIL PROTECTED] Fax: +49(251)83-31653
