If C and D are two non-empty sets, then the cartesian product, C × D is the set of all ordered pairs (a, b) with the first element from C and the second element from D. Similar to the other product operations, we use the same multiplication sign × to represent the cartesian ...
In this section, the Cartesian product of two sets with generic few elements is going to be provided. Consider two sets A = {a1, a2, a3} and B = {b1, b2, b3, b4}. The Cartesian product A × B, as seen previously, is the set of all ordered pairs, meaning that the first ...
This chapter describes the Cartesian products of sets, relations, and functions as relations. The set of all ordered pairs (x, y) such that x ∈ X and y ∈ Y is called the Cartesian product of the sets X and Y and is denoted by X × Y. Cartesian products of sets occur very often...

Cross product Definition Given two relation instancesR1, over set of attributesU1, andR2, over set of attributesU2– withU1andU2disjoint – the Cartesian productR1×R2returns a new relation, over set of attributesU1∪U2, consisting of tuples {t|t(U1) ∈R1andt(U2) ∈R2}. Here t(U) de...
