What's new since 1.41.3 (in a nutshell)
---------------------------------------
1. Fancier generic interface and the interface-building "Fx toolkit."
nxqddb(1) uses the toolkit and replaces xqddb(1).
2. As a consequence of the Fx toolkit, configuring search results,
printing etc. are greatly simplified.
3. Exclude option to attributes to exclude them from indexing
4. Separators option to attributes to specify the characters that
separate words (i.e. keys).
5. Reduced attribute identifiers have been re-introduced. This
Schema option reduces the size of both the Database and Index
files by up to 60%.
6. Misc. bug fixes and manual page updates
7. The manual has been expanded significantly and includes chapters
on programming.
8. *Lots* of other nifty additions
What is it?
-----------
Qddb is a database suite that allows you to create relations,
add tuples, modify tuples, delete tuples, and search for tuples
in a fast and very flexible way. Qddb revolves around the
idea of a "tuple tree," where tuples are stored and manipulated
in an intuitive, pre-joined way.
Qddb supports the following search techniques: regular expressions,
words and word ranges, numbers and numeric ranges, and dates and date
ranges. Approximate matching is coming soon. Qddb 1.42 can use Tcl as
its configuration language, so you can build custom interfaces to your
Qddb databases with it. We provide a reasonably nice generic interface
so you can be up and running quickly. There are manual pages for all
the utilities and Tcl commands, and we include draft 1 of a manual
(qddb-1.42/Doc/Manual).
Qddb 1.42 can be obtained from:
ftp.ms.uky.edu:/pub/unix/qddb/qddb-1.42.tar.gz
If you choose to use the Tcl/Tk interface, you'll need
Tcl 7.3 and Tk 3.6p1, as well as [incr Tcl] 1.5 for the toolkit.
We highly recommend the TclX and BLT extensions as well.
Read the FAQ and README; the user's manual in qddb-1.42/Doc/Manual
has a nice chapter to get you started. A new tech-report on
Qddb algorithms/structures will be available in a few days:
ftp.ms.uky.edu:/pub/unix/qddb/papers/255-95.ps.gz
This is BETA software, but we have been happily using the underlying
stuff for years. We have tested Qddb on MIPS Ultrix, OSF/1 (Alpha),
BSD/{386,OS}, Linux, HP/UX, SunOS and Solaris. We have reports that it
works under UnixWare, FreeBSD, NetBSD, Irix, and Sony NeWS. If you have
a different operating system or architecture, we'd appreciate hearing
from you.
***** From the README *****
QDDB stands for 'Quick and Dirty DataBase' (due to the nature of its origin)
and is rapidly evolving. Most of the code has changed drastically (or has
been totally rewritten) from the original version and is now much more
stable. The program(s) are currently in BETA condition, so there are
undoubtedly numerous bugs that we would appreciate hearing about. Suggestions
and bug reports are also quite welcome.
There is a mailing list 'qddb-users@ms.uky.edu' that you can
subscribe to for general discussion/information about qddb. Send mail to:
'qddb-users-request@ms.uky.edu'
with the subject of 'subscribe' and a body containing your name/e-mail address.
I monitor this list and I will usually answer posted questions. For bug
reports, you may wish to submit them to both 'qddb-users@ms.uky.edu'
and 'qddb-bugs@ms.uky.edu' so that other qddb users may benefit from your
ill experiences.
Please note that minor Qddb versions are generally announced *only*
to the qddb-users mailing list.
