Hi I need a little help with finding candidate key with FD:
given relation : R{x,y,z,s,t,u,w}
FD: {s->x , t->y , x->y ,xy->tuz}
is the candidate key {s,w} ?

Re "is this right": Show the steps of your work following your reference/textbook, with justification--not all terms/notations are standard & we don't know exactly what algorithm/method you are following & we want to check your work but not redo it & we need your choices when a process allows them & otherwise we can't tell you where you went right or wrong & we don't want to rewrite your reference.

Please provide enough code so others can better understand or reproduce the problem. – Community Jan 16 '22 at 12:46
