For a database system, one needs a query language. I have this. One also needs a logical algebra to provide a starting point for query optimization. I also have this. But for actually doing query optimization, one needs a physical algebra. I still need the physical algebra.

Can you recommend any literature which tells me how to define this kind of thing and what would be a good formalism to define the physical algebra?
People have mentioned the phrase `attributed grammar' in this context...
