Explanation Given: SQL uses the FROM clause to identify the n-ary relation the query is applied to, the WHERE clause to specify the condition of the selection operation, and the SELECT clause to specify the projection operation that is to be applied. The SQL statement: SELECT Supplier, Project FROM Part_needs, Parts_inventory WHERE Quantity ≤ 10 Is used to find the P 1 , 3 (on the Supplier and Project attribute) of the selection of the 5-tuples in the Part_needs and Parts_inventory databases in tables that are given that satisfy the condition: Quantity ≤ 10. TABLE 11 Part_needs Supplier Part_number Project 23 1092 1 23 1101 3 23 9048 4 31 4975 3 31 3477 2 32 6984 4 32 9191 2 33 1001 1 TABL To determine (b) What is the output of this query given the databases in Tables 9 and 10 as input?
