Data is typically produced by multiple systems and certain systems may produce similar data that needs to be combined vertically. That is, the rows need to be stacked on top of one another. A use case we'll use in this recipe is combining sales data from two different sales systems, in order to get the total sales dataset prepared. This is a typical scenario you may encounter when your organization is operating multiple systems, is migrating from one system to another, is maintaining legacy systems, or is integrating systems from a partner or acquired company. In this recipe, we'll combine multiple datasets using Union.
