Hi Dan,
I've edited the firebird glossary entry and removed the database keyword, so the term "database" should now link to a glossary entry with the same name. Volunteers for the role of glossary moderator (approving new entries and editing existing entries) are always welcome!

I'm curious about the discussion you refer to, as it seems it no longer exists.
Edited to add: The term "database" now seems to link to the
SQL glossary entry, so I've just edited that too...
