All,

I am pleased to announce the release of Muldis::DB version 0.2.0 for Perl 5 on CPAN. You can see it now, with nicely HTMLized documentation, at:

  http://search.cpan.org/dist/Muldis-DB/

This is a semi-major release, though I am not announcing it too widely, but just to the Muldis-DB and TTM and DBIx-Class lists (others can just notice it on CPAN).

The main reason I am bringing this release to your attention is that it is the first one where the documentation has significantly fleshed out what the system-defined operators of Muldis D are.

In particular, it is the first release to define a significant fraction of relational algebra or calculus operators, which are absolutely necessary to work with relational databases and/or to substitute for SQL.

See http://search.cpan.org/dist/Muldis-DB/lib/Muldis/DB/Language/Core.pod specifically to read about the operators, and the data types they apply to.

This release, and the prior one, saw various other significant changes, including renamed and split up files, but no significant additions of functionality to the code itself (which should be coming soon).

See the "Changes" file for more details of what changed in the last few releases.

Generally speaking, I am trying to have a new release about once every week, so today's shows my progress part-way through defining the Muldis D operators and defining the system catalog / meta-model.

Thank you. -- Darren Duncan
