Consider the given relational schema:
Suppliers(sid:integer, sname:string, city:string, street:string)
Parts(pid:integer, pname:string, color:string)
Catalog(sid:integer, pid:integer, cost:real)
Assume that, in the supplier's relation above, each supplier and each street within a city has a
unique name, and (sname, city) forms a candidate key.
No other functional dependencies are implied other than those implied by primary and
candidate keys.
Which one of the following is TRUE about the above schema?
O The schema is in 2NF but not in 3NF
O The schema is in 3NF but not in BCNF
O The schema is in BCNF
Save Answer
Q2 Normal form
The relational schema for Student Performance of a course (s_name, c_No, s_id, grade) has the
following functional dependencies:
s_name, c_No + grade
s_id, c_No + grade
s_name - s_id
s_id +s_name
The highest normal form of this relation scheme is
O BCNF
O 2NF
O 3NF
