**Figure 5.7: Result of a Theta-Outerjoin**

The table illustrates the result of a theta-outerjoin operation, with columns labeled \(A\), \(U.B\), \(U.C\), \(V.B\), \(V.C\), and \(D\). The data is organized as follows:

- Row 1: 4, 5, 6, 2, 3, 10
- Row 2: 4, 5, 6, 2, 3, 11
- Row 3: 7, 8, 9, 2, 3, 10
- Row 4: 7, 8, 9, 2, 3, 11
- Row 5: 1, 2, 3, ⊥, ⊥, ⊥
- Row 6: ⊥, ⊥, ⊥, 6, 7, 12
