Set Operation: Union - Concept

Concept Concept (1)

A set operation is the collection of two data sets. Two data sets can be added together, which is called a union set operation. For example, the union of data set A with the data set B (A U B) is the set of all things which are members of either A or B. Set operations include union, intersections and complements.
