UNIFY/ACCELL would do the job nicely since it currently does support databases in the area you are talking about. If you will be developing and running under Unix platform, it is probably the best product for the job. It has access methods built it to support hashing (on keys); B-trees; Links; and Sequential. Let me know the platform and we can talk further. Tom

Could this be the SAME Tom R. Stilz who is employed by Unify Corp. ?? (Just wondering.) We have used Unify here for serveral years and I have a few stories to tell about why Unify may not be the product to use in a large database. Send me e-mail for details. By the way *I am not associated with Unify Corp, except as a customer*. -- Kevin Brighton UUCP: {geac,utzoo,utgpu}!syntron!jtsv16!kevin JTS Computer Systems Ltd. or: suncan!jtsv16!kevin Toronto, Ontario, CANADA or: uunet!jtsv16!kevin +1 416 665-8910 Internet: kevin@jtsv16.jts.com Or just forget it

I am looking for any information on large (>10GB) real-world databases on Unix, using Oracle/Ingres/Informix/Sybase... Thanks in advance. Tony Scott
