Consider relation SUPPLY (S#, Sname, P#, Qty) with supplier names unique such that: F: fd1: S# Sname; fd2: Sname S#; {S#, P#}

Consider relation SUPPLY (S#, Sname, P#, Qty) with supplier names unique such that:
F: fd1: S#  Sname; fd2: Sname  S#; {S#, P#}  Qty
S# represents a supplier number, Sname represents a supplier name, P# represents a part number, and Qty represents the quantity of a specific part supplied by a specific supplier.

a. Is there a 3NF violation in SUPPLY? If yes, explain. If no, is there a BCNF violation in SUPPLY? Explain.
b. Decompose SUPPLY if necessary so that the resulting relational schema is in BCNF. Is your design attribute-preserving, dependency-preserving, and a lossless-join decomposition? Explain.
