dependent on the candidate key. So this table satisfies the third paradigm.And we'll look at the main attribute: (wno,pno)->eno; Eno->wno. Obviously Wno has a transitive dependency on the candidate key (Wno,pno), so it does not conform to BCNF.The solution to this problem is to split into two tables: Management Table EP (ENO,PNO,QNT); sheet ew (ENO,WNO). But doing so causes the function dependency (wno,pno)->eno to be lost.Although, not satisfying th
