A useful analogy indeed, thanks.
- garmaine 6y agoIt goes a bit deeper than an analogy, but regardless I’m glad it helped! EDIT: To explain, the relational algebra IS a map-reduce functional programming language. The relational calculus IS a logical programming language. They just use tuples and sets instead of the more familiar lists and strings of LISP, Forth, Prolog, etc. And the sibling comment further up is right to point out that there are mechanical transformations to turn one into the other, just like there are automatic ways to compile Prolog into LISP (and vice-versa, though that is rarely done).
