I'm not aware of any 'free software database' that is down to 
my level of sophistication. What such animal can you recommend 
for use with GNAT Ada 3.11p under NT?  


I just fear out of pure ignorance that many of the things that
are available in database systems but unneeded in this application
-- locking, transactions, multi-user capabilities, joins, 
set-at-a-time processing, triggers, you-name-it -- carry a 
pretty heavy cost in performance and general bulk of the 
application, ie number of things that can go wrong.  What I 
got working today -- a direct_io file with a couple of indexes 
built in memory each time the application runs -- works fine and 
appears to be able to create a few thousand records per second 
and then read and update over 1000 per second.

It's also amusing to me that after my data is refined into its final
form, I will create an Ascii text file of it to pass to the next
application.  Using direct_io with a record padded with a crlf,
the step of creating the Ascii version of the file is null,  there's
nothing to do. This random access Ascii via direct_io matches Btrieve 
in speed, and I can view and patch my database with edlin.
