We have a need for a database that can handle binary data of arbitrary length. We've looked at Oracle, Ingres, Sybase, Informix, and Unify, and Unify is the only suitable one we've found thus far. We've recently learned that Empress may have the capabilities that we require and we're in the process of obtaining literature on it. Are there any RDBMSs other than Unify and (possibly) Empress that can handle binary data of arbitrary length (in addition to doing all the other good stuff you typically expect from a RDBMS)? -------------------------------------------------------------------- Bill Mitchell whm@sunquest.com Sunquest Information Systems sunquest!whm@arizona.edu Tucson, AZ {arizona,uunet}!sunquest!whm 602-885-7700

I'm not sure what you mean arbitrary length, but we're using Informix on Plexus computers to store compressed image data. This is of varying length. -- Bob Breedlove SYSOP: BOBsBBS (916/929-7511) pacbell!sactoh0!bfbreedl

The data size (length) will be up to 2 gigabytes. Hope this helps. If you have any further questions, email me. -b Fodder

I dont know what your hardware requirements are, but we use an RDBMS called InterBase on the Apollo platform. InterBase has a data type called a BLOB(Basic Large OBject) that is of arbitrary length and can contain either textual or binary data. InterBase is available on Apollo, Sun, and Vax hardware from: Interbase Software Corporation 209 Burlington Road Bedford, MA 01730 617-275-3222 Stephen Peterson UUCP: {decwrl!decvax, mit-eddie, attunix}!apollo!peterson_s ARPA: peterson_s@apollo.com

Except ours stands for Binary Large OBject. Of course, ours isn't shipping yet...

Sybase will have this capability in version 4.0, which should be in beta release soon (sorry I can't be more specific than that). I will forward your message to our sales department. -- Jeff Lichtman at Sybase {mtxinu,pacbell}!sybase!jeffl "Saints should always be judged guilty until they are proved innocent..."

We've looked at Oracle, Ingres, Sybase, Informix, and Unify, Rdb/VMS for the VAX can handle this. We use segmented strings. Each segmented string is made up of an arbitrary number of vectors which are linked together. Each vector can contain up to 64K of unformatted data. This discussion assumes that you have a lnaguage which can perform operations on binary data of arbitrary length. Is that true? - Barry L. Wallis - Digital Equipment Corporation - Irvine, CA

I have heard that a new release of Informix is due out that will include binary data types. I do not have any of the details though. I would suggest that you give them a call to verify this and also the release date for the new version. -- J.

Is anybody familiar with the DEC Conver/merge utility? I have 2 fixed-length record indexed files (about 179,000 disk blocks large, 1 file). I am doing daily convert/merge of fixed record-length seqeuential records to these indexed files. The first file has a record length of 72, and the 2nd file, 127. My problem is that the first convert/merge only takes 10 minutes,whereas the second one takes 2 hours, even though the number of records in the second one is less than the first. The second indexed files is structured with duplicate keys. Any ideas? thanx in advance. :wq . :wq! ZZ
