Announce: new DB-based Configuration System (beta)

[Ben Clewett]

Dear Ian,

You request some feedback.  I have looked at the schema and I was just 
wondering whether you might want to consider adding a PRIMARY KEY to all 
tables, as well as some FOREIGN KEY definitions to join the tables together?

Although the schemas will work perfectly without these, this will help 
the DBMS forming good JOINs where requested, speeding up queries.  This 
will also introduce referential integrity.  Which will stop corruption 
(miss-linked information and missing linked information) being entered 
into the system either as user error or a programatical error.

I use these ideas as standard on all work I do, in the context of OSS 
projects and my paid-work, and find this can make an enormous difference 
in the long run.

Regards, Ben Clewett.
