Hello.

I was wondering where I could find a formal definition of the relational
algebra grammar.

You can find a grammar for Tutorial D at the following URL; although,
it's not quite you want:
http://www.hughdarwen.freeola.com/Th...esto.web/D.GRM

One can invent any number of formal definitions of the relational
algebra depending on which operations one chooses as primitives.

Indeed, Darwen's relational algebra is called A... I think it
appears at _TTM_, but not formally.
