Abstract

Before describing OUR SOLUTION, we will first define some key terms. Definition: TRANSITIVE CLOSURE: In the following SQL query SELECT T1.C1 FROM T1, T2 WHERE T1.C1=T2.C1 AND T1.C1 '0328' one can infer that T2.C1 ='0328' must also be true because T1.C1 T2.C1. This is referred to as transitive closure.
