-----BEGIN PGP SIGNED MESSAGE-----
Current version: 1.42.6
Release date: Mon Nov 27 11:46:58 EST 1995
Where: ftp.ms.uky.edu:/pub/unix/qddb/qddb-1.42.6.tar.gz
qddb-1.42.6.tar.gz fully supports Tk4.0. Read the WHATSNEW
file in that distribution for more verbose info about what
changed. The new INSTALL file should help you install Qddb.
What's new since 1.42.5pl3?
- ---------------------------
o New "expert search" query-builder (integrated).
Allows specification of fully parenthesized
expressions, possibly mixed with ad-hoc queries.
o Many bug fixes and manual page/guide updates
o Many new bindings
o Config file operations are now restricted by
the Schema and type of file (i.e. search results
configurations are all you will see if you try
to read in a search results config).
o New "HashType = 1" Schema option; uses a new
hash function that performs well with numeric
data, Web URL's, etc.
o Windows now fit reasonably on a laptop screen if you
configure the fonts properly. You can still have Schemas
that overflow the width of a laptop screen; I use a virtual
screen to get around this.
o INSTALL file now documents things we know about compiling
on various architectures.
o Lots of other stuff.
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 fashion.
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 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
(Doc/Manual).
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. Full
support for Tcl 7.4 and Tk 4.0 is available in Qddb 1.42.6.
Read the INSTALL and README files; the user's manual in Doc/Manual
has a nice chapter to get you started.
