I'm pleased to announce the 0.92 release of Ratcl.
(This is a Tcl-specific announcement - if you're interested in other
languages, you may still want to read on, as more bindings will
follow later.)
Ratcl is a completely new development which implements Relational
Algebra in Tcl. Take that with a grain of salt though: the Ratcl
design also deals with set- and vector operators, and bridges the gap
with databases and persistence by adopting a Metakit-compatible file
format. Ratcl aims to provide new persistence solutions for
scripting languages.
Being a bit of everything, there is a lot still left to explore, as I
try to find a balance which will make it easy to efficiently deal
with a wide range of data requirements. This release allows you to
see what Ratcl is today, and where it's headed.
For information about this release, see http://www.vlerq.org/vlerq/250
Ratcl was recently presented at the Tcl 2005 Europe conference in
Bergisch Gladbach - the paper and slides ar available at http://
www.equi4.com/docs/tcl2005e/ and form a good introduction, but keep
in mind that the syntax described in the paper has already evolved
further. The most up-to-date documentation is in the ratcl.kit
starkit and the ratcl.pdf docs.
The Ratcl development is part of a larger project called "Vlerq", see
http://www.vlerq.org to get more information about the scope and
goals of this long-term research project, including other language
bindings.
I welcome all feedback and suggestions, preferably on the wiki-based
discussion forum on the Vlerq website.
Enjoy,
Jean-Claude
