Concatenation example

This workflow demonstrates the concatenation of two or more tables. It also shows how to treat the missing columns by selecting either the union or intersection of columns.

Three datasets containing sales records are used. Two of them, for the years 2010-2011 and 2012-2013, contain exclusive column "card". Another data set has an exclusive column "insurance".
