5.1 Relational Operations on Bags

5.1 Relational Operations on Bags. Bags or multisets (See Fig. 5.1) 5.1.1 Why Bags? Some relational operations are considerably more efficient if we use the bag model; e.g., union or projection. (See Fig. 5.1 and Fig. 5.2) 5.1.2 Union, Intersection, and Difference of Bags
