Solution

1)

Tuple relational calculus : T:< sid >|SSuppliersPparts CSP (P[sid] =S[sid]P[pid] =C[pid]T[sid] =S[sid] -|sid=p1)}

Domain relational calculus : (X:sid)|SNA Suppliers(X, SN, APP NL(Parts(P, P N, L)C SP(X, P, C) ^ SP[sid]/= \'p1\';

2)Tuple relaional calculus : {T:< sname > ^ T:<Add(P)>^ T:<Add(QTY) T1Suppliers(XP arts(color] =redYCatalog(Y[pid] =X[pid]Y[sid] =T1[id]))T[sname] =T1[sname]}

Domain relational calculus: Y:sname^add(parts)^add(QTY)|XZ Suppliers(X, Y, Z)PQR K SP(X, P, K))}
